The Radium Engineering Universal Check Valve is a 1-way valve that allows flow in one direction only. It features a lightweight anodised aluminium body, FKM seals and stainless steel hardware, and is compatible with gasoline, ethanol, methanol, diesel, water, coolant, oil and more.
The internal plunger has an aerodynamic shape for smooth laminar flow. All female AN ports accept 37-degree flare male fittings and/or ORB male fittings, and the flow direction is laser etched on the side of the valve. In native form the valve has an 8AN female inlet and a 10AN male outlet; the -06, -08 and -10 kits add adapter fittings to convert both ends.
