These fittings are commonly used in refrigeration, automative and low presure applications.

SAE 45° SAE J512

SAE male has 45° flare which seals against 45° seat in female. Male can also seal against 45° flared tubing with nut and sleeve.

7/16 – 20, 1/2 – 20, 3/4 – 16 & 7/8 – 14 are the same thread form as JIC 37° flare. Some fittings in these sizes have both JIC 37° & SAE 45° seats.

Society of Automotive Engineers (SAE) fittings are commonly used in refrigeration, automotive and low-pressure applications.

SAE O RING FLANGE – CODE 61 & CODE 62 SAE J518, ISO 6162

RYCO O RING FLANGE CODE 62C

The male connector has a flange with an O Ring groove on the face.

The female can be a flange block or port with smooth face to accept the O Ring, and four threaded bolt holes in a rectangular pattern.

The connection is held together using either a split or solid flange clamp, fitted over the male flange head and drawn up to the female port using the four bolts. This compress the O Ring forming a seal between the male flange and the flat female port face.

SAE J518, DIN 20066, ISO/DIS 6162 and JIS B 8363 are all interchangeable, except for bolt sizes.

SAE 45° Flare – SAE J512

SAE male has 45° flare which seals against 45° seat in female. Male can also seal against 45° flared tubing with nut and sleeve.

7/16 – 20, 1/2 – 20, 3/4 – 16 & 7/8 – 14 are the same thread form as JIC 37° flare. Some fittings in these sizes have both JIC 37° & SAE 45° seats.
