Material Composition: Fittings from forged or cast pressure resistant carbon steel with a zinc-trivalent anti-corrosion coating. 304 JIC fitting interchange to the following manufacturers: SAE 070111, Aeroquip 221000, Weatherhead C5115. JIC SAE 37° and SAE ORB (O-Ring Boss) conform to SAE J514 technical specifications. 37° JIC Long Flare Nut. 304 JIC fitting interchange to the following manufacturers: SAE 070111, Aeroquip 221000, Weatherhead C5115. Material Composition: Fittings from forged or cast pressure resistant carbon steel with a zinc-trivalent anti-corrosion coating. JIC SAE 37° and SAE ORB (O-Ring Boss) conform to SAE J514 technical specifications. 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.
