Straight ORB to Male Flare Fittings

Description

ORB stands for “O-Ring-Boss” which is an SAE straight cut thread that seals by the use of an o-ring. -16 is the most common size found in my cooling system parts. The opposite end of the ORB fitting is a 37° JIC flare and seals via a matching 37° seat on the hose-end. No thread sealant is necessary or recommended with these fittings.
