JIC37 Flare Thread

The Society of Automotive Engineers (SAE) specifies a 37ํ ํ angle flare or seat be used with high pressure hydraulic tubing.  These are commonly called JIC couplings.

The JIC37 ํ 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.
