About this part
A 1-way check valve permits flow in 1 direction only. The Radium Engineering universal check valve features a lightweight anodized aluminum body with FKM seals and stainless steel hardware. As shown below, the internal plunger's aerodynamic shape warrants a smooth laminar stream.
All female -AN ports can accept 37 degree flare male fittings and/or ORB (O-ring boss) male fittings. As depicted below, the flow direction is laser etched on the side of the part.
The check valve is compatible in multiple applications including gasoline, ethanol, methanol, diesel, water, coolant, oil, etc.
The 10AN kit includes the 20-0534 check valve body but adds all the necessary adapter fittings to convert both the inlet and the outlet to 10AN male and/or 10AN female.
