Product Description:

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.

As seen above, 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.

20-0534 UNIVERSAL CHECK VALVE
In it's native form without adapter fittings, the universal check valve uses a 10AN male outlet and a 8AN female inlet.

The 20-0534-XX kits below will cover most scenarios. 

20-0534-06 UNIVERSAL CHECK VALVE KIT, 6AN
The 6AN kit includes the 20-0534 check valve body but adds all the necessary adapter fittings to convert both the inlet and the outlet to 6AN male and/or 6AN female.

Shown below are all of the adapter fitting scenarios for this check valve kit.

20-0534-08 UNIVERSAL CHECK VALVE KIT, 8AN
The 8AN kit includes the 20-0534 check valve body but adds all the necessary adapter fittings to convert both the inlet and the outlet to 8AN male and/or 8AN female.

Shown below are all of the adapter fitting scenarios for this check valve kit.

20-0534-10 UNIVERSAL CHECK VALVE KIT, 10AN
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. 

Shown below are all of the adapter fitting scenarios for this check valve kit.
