About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

45° Flared Fittings for Copper and Brass Tubing

Metric and UN/UNF
(SAE Straight) Male
Threads with Gasket

Temperature Range: -65° to 250° F
Tubing: Use with seamless brass and copper that meets ASTM B280

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.

Metric and UN/UNF (Straight) threads have a gasket to protect against leaks. Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
