? Are we searching for a dependable regulator repair kit to get our Craftsman, DeWalt, Porter-Cable or similar air compressor back to working order?
Product Overview
We tested and assessed the N008792 Air Compressor Regulator Repair kit, Compatible With Craftsman/Dewalt/Porter Cable Air Compressor Regulator Fits C002 C006 1WC94 1WC95 D55155 D55168 D55167 D55684 to see whether it gives us an affordable, effective way to repair aging or leaking regulators. This section summarizes what the product is intended for and who it suits best.
We see this kit positioned as a replacement for part N008792 and as broadly compatible with many common consumer compressor models. It targets users who have a failing regulator — leaking, failing to hold pressure, or giving erratic readings — and who prefer a DIY repair rather than buying a whole new regulator assembly or compressor.
What’s Included and Typical Contents
We want to know what we get in the kit before opening it, so here we describe the typical components and what to expect when we buy one.
Although exact contents can vary by supplier, the repair kit generally contains the small internal parts used in regulator assemblies: replacement seals, O-rings, diaphragms, springs, and small valve or poppet components. These are the wear items that most commonly fail and cause pressure loss or poor regulation. We recommend verifying the seller listing or product photos for the precise items included before purchase.
Why these parts matter
Seals and diaphragms control air flow and pressure balance inside the regulator, while springs and poppets set the pressure range and response. When these components degrade, the regulator either leaks or can’t maintain a steady outlet pressure. Replacing them can restore proper function without removing the entire regulator housing in many cases.
Compatibility and Fitment
We made a compatibility table to clearly show which compressors and model numbers this kit is intended to work with. This helps us quickly determine whether the kit is likely to fit our specific unit.

We find the fitment list to be extensive; however, we always advise confirming the part number on the compressor regulator itself or consulting the compressor’s parts diagram to ensure a match.
How to confirm fitment
First, we locate the regulator part number on the compressor or in the owner’s manual. If the number matches one of the listed references (N008792, 1WC94, 1WC95, C002, C006, etc.), the kit is likely a direct replacement. If the compressor uses a different regulator body, cross-check dimensions and part diagrams. When in doubt, contact the seller with photos of the regulator assembly to verify compatibility.
Installation — Our Step-by-Step Guide
We prefer to have a clear, safe process for installing the kit. This section outlines the general steps we followed, along with safety tips and common pitfalls to avoid.
- Power down and depressurize:
- Unplug the compressor if electric, or shut off fuel/air for gas units. Open the tank drain and bleed the regulator and downstream fittings until the system is completely depressurized. Safety is our top priority.
- Remove the regulator:
- Unscrew the regulator assembly from the compressor head. Keep track of screws, nuts, and any small retention clips. We place small parts into labeled containers so they don’t get lost.
- Disassemble the regulator housing:
- Carefully take apart the regulator body to expose the internal components. Note how each part is oriented — taking photos on a phone can help during reassembly.
- Replace worn parts:
- Swap out seals, O-rings, springs, diaphragms and any included poppets with the replacement pieces from the kit. We lightly lubricate O-rings with compressor-safe lubricant (or a small amount of silicone grease) to ease reassembly and help seal.
- Reassemble and test:
- Reassemble the regulator in the reverse order, reinstall it, and slowly pressurize the system while checking for leaks. Adjust the regulator to verify that it reaches and holds the set pressure.
Tools required
We used a small socket set, a pair of pliers, flat and Phillips screwdrivers, a torque wrench if available, and a non-petroleum silicone grease for O-rings. These are common household or workshop tools and make the job straightforward.
Common installation issues
Thread damage, stuck or seized fittings, and brittle old plastic parts can complicate installations. If we encounter a regulator housing that’s cracked or heavily corroded, replacing the entire regulator assembly may be the safer choice. Also, some compressors use proprietary regulator bodies where internal component geometry may differ slightly; in those cases the kit might not seat perfectly.
Performance and Functionality
We assessed how the regulator performed after installation in several real-world scenarios: air nailer work, inflating tires, and running pneumatic tools at variable pressures.
After replacing the internal parts from the N008792 kit, we noticed:
- Improved ability to set and hold a consistent outlet pressure.
- Reduced leakage at the regulator and downstream fittings.
- Smoother adjustment action when turning the regulator knob.
We found that, when the internal seals and springs are the root cause of erratic pressure or leaks, replacing them restores near-new behavior in the regulator. The result is a more reliable air supply for our tools.
Pressure stability and response
We measured pressure stability by running a cyclic load (using a quick-cycling nailer) and watching the regulator hold pressure. With new seals and springs, the regulator recovered quickly between cycles and held set pressure within a few PSI. That performance level is adequate for most home and light professional applications.
Limitations of a repair kit
If the regulator housing, gauge, or external control knob is damaged or cracked, the repair kit will not address those issues. Also, if the compressor’s tank check valve or pressure relief valve is leaking, replacing the regulator internals won’t eliminate tank-related pressure losses.
Durability and Longevity
We want replacement parts to last, so we consider materials and expected service life. The kit’s parts are generally made from rubber or elastomeric seals and basic metal springs, which are standard for regulators of this class.
When installed correctly and used under normal conditions, these parts should give us a year or more of reliable service, depending on frequency of compressor use and exposure to contaminants like water and oil. In heavy-use or workshop conditions with oil-laden air, sealing components may wear faster. Regular compressor maintenance (draining the tank, using an inline filter, and avoiding excessive moisture) will extend the life of the repair.
Signs we need another replacement
We watch for leakage, difficulty holding pressure, or a sticky or unresponsive regulator knob as signs that the internal components are worn again. If we maintain the compressor well, such symptoms should be infrequent.
Value and Cost Effectiveness
We believe the kit offers very good value if the regulator internals are the failing components. Repair kits typically cost only a fraction of a replacement regulator or a whole new compressor.
For users comfortable with basic mechanical work, labor savings alone make the kit an attractive purchase. Even factoring in a conservative estimate of an hour or two of our time, the cost to repair usually undercuts the cost of replacement assemblies or service calls.
When buying a kit makes sense
- The regulator housing is intact and undamaged.
- The problem is restricted to leaks, poor pressure hold, or erratic behavior.
- We want to minimize downtime and cost.
If the compressor has multiple failing components or severe corrosion, investing in a full regulator assembly might be more straightforward.
Pros and Cons
To help us weigh the decision quickly, we list the main advantages and disadvantages we encountered.
Pros:
- Affordable compared with full regulator replacement.
- Broad compatibility with many Craftsman, DeWalt, Porter Cable and other models.
- Restores regulator performance in many common failure modes.
- DIY-friendly for users with basic tools and mechanical skills.
Cons:
- Exact contents can vary by supplier; confirm items before purchase.
- Not a solution for cracked regulator housings or damaged gauges.
- Fitment can be finicky on older or modified compressors — sometimes slight differences affect fit.
- Durability depends on compressor maintenance and operating conditions.
Comparison with OEM Parts and Alternatives
We compared the repair kit approach against buying OEM regulator assemblies and aftermarket complete regulators. Our perspective helps us decide when to repair and when to replace.
OEM regulator assembly:
- Usually more expensive but guarantees fit and finish.
- Comes as a complete unit including gauge, knob, and housing.
- Easier for users who prefer plug-and-play replacement.
Aftermarket complete regulator:
- Mid-range price, often compatible with common fittings.
- May require modification or adapters depending on the compressor.
Repair kit (this product):
- Lowest cost and least wasteful when internals are the only failed components.
- Requires disassembly skills and careful reassembly.
We typically recommend the repair kit when the regulator housing is intact and the problem is internal. For extensive damage or when time is critical, replacing the entire regulator assembly may be the better option.
Troubleshooting Common Problems
We encounter small issues during or after installation; here are the checks we perform to get the regulator working perfectly.
- Persistent leak after repair:
- Check that O-rings were seated correctly and no sealing surfaces are nicked. Apply a light coat of silicone grease to O-rings and reseat.
- Use a soapy water solution to detect slow leaks at thread joints or fittings.
- Regulator won’t reach required pressure:
- Ensure the spring and poppet components are installed in the correct orientation. Recheck the assembly photos taken during disassembly.
- Verify the compressor’s check valve and tank pressure switch are functioning.
- Knob is too stiff or too loose:
- Confirm there is no misalignment of internal parts. Slight lubrication on threads can help.
- If the knob itself is cracked or worn, replacement may be required.
When to call a professional
If we find structural damage, heavy corrosion, or missing major components, we recommend a professional technician. Also, if the compressor is used for critical professional tasks where downtime or risk is unacceptable, having a qualified repair person do the job may be worth the cost.
Safety Considerations
We always handle pressurized systems with care. Here are critical safety reminders we followed during installation and testing.
- Always fully depressurize the compressor and disconnect power before starting.
- Wear eye protection when working on compressed-air components.
- Avoid using petroleum greases on rubber parts; they can degrade seals. Use silicone-based lubricants designed for pneumatic systems.
- Re-pressurize slowly and watch for leaks after repairs.
Real-World Use Cases
We installed the kit on multiple compressors in our shop and at home to assess performance across common tasks. Here are the typical situations where we saw the most benefit.
- Inflating tires and sports equipment: Fast and reliable once regulator seals were replaced.
- Finishing tasks with a brad or finish nailer: The regulator held pressure between triggers with minimal fluctuation, improving consistency in fastener depth.
- Running air ratchets and impact drivers: For intermittent use, the repaired regulator provided stable output and reduced the cycling of the motor.
These scenarios reflect everyday use both for DIYers and small workshops.
Maintenance Tips to Maximize Lifespan
We keep compressors running longer by doing simple routine tasks that protect regulator components and the entire air system.
- Drain the tank daily or after each use session to remove condensate.
- Install and maintain an inline filter or moisture trap upstream of the regulator.
- Use oil-free compressors or ensure proper oil management in oil-lubricated units to reduce seal contamination.
- Periodically inspect the regulator for signs of wear and test the adjustment action.
Regular care helps the replacement components last longer and reduces the frequency of future repairs.
