Regulator assembly location on the compressor ↑
Knob turns but does not reduce pressure?
Knob cracked or broken?
Air leaking from inside or below regulator knob?
FAQ's
The knob blew off - This happens when the threads of the regulator knob have worn out. The spring causes the knob to pop off of the manifold assembly.
The pressure will not decrease - If the air pressure gauge for the regulated air (not the tank pressure) will not adjust up or down and the tank pressure gauge shows that the pump is reaching cut-out pressure and cuts off, then the knob and/or internal regulator parts are worn.
After the air compressor pumps up and cuts off, air leaks from around the regulator knob - This is due to worn o-rings in the internal portion of the regulator.
Do I need to replace the spring? - In most cases, the spring is still functional and does not need to be replaced. The common failure is in the internal regulator components and knob, which this kit addresses.
How do I know if this will fix my air compressor? - If your compressor runs but the pressure cannot be adjusted, or the knob spins without effect, this is one of the most common regulator failures on these units.
Do I need to take the entire compressor apart? - No. This repair is limited to the regulator assembly and does not require disassembly of the air compressor.
Why not just replace the whole regulator or compressor? - The entire regulator is a one piece die-cast assembly that cannot be replaced. This kit replaces all of the integral parts of the regulator which addresses all of the symptoms above. This repair is much cheaper than purchasing a new air compressor that may not be of the same quality of the one you are trying to repair.
Why this kit works:*Includes the parts that actually wear out
*Fixes the root cause, not just the symptom
*Prevents having to tear it apart twice
This addresses the internal wear that causes pressure adjustment failure.
