139-0009 - Check Valve
Description:

OEM check valve (ball & spring included) for 3/8" size tube. Replace if unit struggles to re-start or air leaks constantly around pressure switch.

This is obsolete, but you can use our CTRD3812-PLUG Check Valve as a replacement (click the part# to order).

Does your air compressor fill up the tank and when it tries to restart, it stalls and then “kicks” the electrical breaker? Does your on/off pressure switch leak from the small unloader valve (on the side or bottom of the switch) after it cuts off, and then continues to cycle on/off? The check valve is one of the most common parts that fails on a compressor and replacing it should rectify these problems. It is a one-way valve that lets air in (but not out), of the tank. Usually there is a diaphragm or a ball and spring inside the valve, and it’s easy for debris and rust to form build-up which will cause the valve to stick open. A new check valve can solve multiple problems at once.
