Straight -16 ORB to -16 Male Flare Fitting – XL

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. Thread Sizes -16 > 1-5/16″-12 SAE -12 > 1-1/16″-12 SAE -10 > 7/8″-14 SAE -8 > 3/4″-16 SAE NOTE: I do offer the option of adding a bung to the blank area between the hex and the last thread on the male flare side. Helpful when trying to send or return water to/ from something.
