How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

45° Flared Fittings for Copper and Brass Tubing
- Temperature Range: -65° to 250° F
- Tubing: Use with seamless brass and copper that meets ASTM B280
- Specifications Met: SAE J512, SAE J513, UL Listed, except socket-connect fittings and fittings with BSPT thread meet SAE J512 and SAE J513 only
No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They require a nut (sold separately) for each tube end. Fittings are also known as refrigeration and SAE fittings. They are brass for good corrosion resistance.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
