*SAE (45° Flare)
A term usually applied to fittings having a 45° angle flare or seat. Soft copper tubing is generally used in such applications as it is easily flared to the 45° angle. These are for low pressure applications - such as for fuel lines and refrigerant lines.
The SAE 45° flare male will mate with an SAE 45° flare
female only.
The SAE male has straight threads and a 45° flare seat.
The SAE female has straight threads and a 45° flare seat.
The seal is made on the 45° flare seat.
All sizes have the same threads as the SAE 45° flare except
-6 and -12. Carefully measure the seat angle to differentiate.
*Note: Some C5, C5E and Lock-On couplings may have
*Note: dual machined seats (both 37° and 45° seats).
