JIC SAE 37° and SAE ORB (O-Ring Boss) conform to SAE J514 technical specifications

JIC Thread Sizes Sizes (SAE J514, 37° Flare)

Commonly referred to as 37° JIC, this connection is widely used in hydraulic systems. When the straight threads are engaged, the 37° male seat seals on the 37° female flare seat. Most thread sizes are identical to the 45° SAE connection as noted (*) below. Care must be taken not to confuse these two connectors, which have different seat angles.
