JIC 37° FLARE & UNO(O RING BOSS) THREADS • JIC is JOINT INDUSTRIES COUNCIL – SAE J514, ISO 8434-2 • UN is UNIFIED NATIONAL – SAE J1926, ISO 11926-2 JIC & UNO (O Ring Boss) thread forms are the same (ASME B1.1). Method of sealing differs. JIC male has 37° flare which seals against 37° seat in female. JIC male can also seal against 37° flared tubing with JIC nut and sleeve. JIC male can also be used with RYCO S134 J-Lok Female Nut and Flareless Olive on Imperial OD tubing.
*JIC (37° Flare)The Society of Automotive Engineers (SAE) specifies a 37° angle flare or seat be used with high pressure hydraulic tubing. These are commonly called JIC couplings. The JIC 37° flare male will mate with a JIC female only.* The JIC male has straight threads and a 37° flare seat. The JIC female has straight threads and a 37° flare seat. The seal is made on the 37° flare seat. Some sizes have the same threads as the SAE 45° flare. Carefully measure the seat angle to differentiate.
