Works on Porter Cable C2002 Type 3
Air was leaking at the compressor and the tank would not hold air. I purchased this replacement check valve and that solved the problem! Before I installed it, I sprayed the inside of the new valve with silicone spray to help keep the rubber seal soft. (I took the old check valve apart and found the rubber stopper was all dried out and would not seal.) The new check valve works perfectly!

My compressor is fixed
My pancake compressor was leaking at the check valve causing pressure fluctuation and eventually no pressure. No place local carries the parts. I am a repeat customer and another device is working because I could obtain the parts. This site is my first choice whenever I search for parts. They are reliable, efficient and not overpriced.
