Radium Engineering Check Valve - Universal - 6AN ORB to 10mm Barb
Radium Engineering builds fittings and fluid management hardware trusted by professional race teams, and this check valve is a straightforward, no-nonsense solution for anyone who needs guaranteed one-way flow in a fuel or fluid system. It's a small part, but getting backflow control wrong can cause real headaches in a catch can or fuel system setup.
This listing covers the 6AN ORB to 10mm Barb version of the check valve, suited to universal fitment across fuel systems, catch cans, AOS setups, coolant overflow lines, oil system protection and vacuum or boost reference lines. As a universal component, it's up to the installer to confirm the ORB and barb sizing matches your existing hose and fitting setup.
Note: Flow direction matters. This valve only allows flow one way, so check orientation and pressure requirements for your specific application before installing.
