Radium Engineering 10AN ORB to 5/16in SAE Male Fitting

Product Description

The Radium threaded adapter fittings are compatible with 10AN ORB (O-ring boss) ports. Because the threads on these fittings are not used for sealing, PTFE paste or thread sealant is not required. The FKM O-ring should be lubricated with engine oil. 

ORB ports are an industry standard and found on many automotive plumbing products, including most Radium products. All fittings include FKM O-rings.
