PA6 check valves for the exhausts of solenoid valves, actuators and limit switch boxes: air gets out while dust, dirt and water stay out.

The exhaust check valve is screwed into the exhaust port and lets the air flow out while preventing dust, dirt and water from entering the device. It is a simple way to protect solenoid valves, pneumatic part-turn actuators and limit switch boxes.
The body is made of black PA6 and comes with two EPDM O-rings. The G1/4" version (also suitable for NPT 1/4" threads) is intended for solenoid valve and actuator outlets; the M12x1 version is designed for pneumatic limit switch boxes and other applications.
