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.
What are SAE fittings?
Society of Automotive Engineers (SAE) fittings are commonly used in refrigeration, automotive and low-pressure applications. These include:
- SAE O RING FLANGE – CODE 61 & CODE 62 SAE J518, ISO 6162
- RYCO O RING FLANGE CODE 62C
SAE Male Connector
The SAE male connector has a flange with an O Ring groove on the face.
SAE Female Connector
The SAE 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.
Connecting SAE Fittings
The SAE 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 Threads Dimensions
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.
