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
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.
NPTF (Dryseal) threads are compatible with NPT threads.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

Supported 45° Flared Fittings for Copper and Brass Tubing
- For Use With: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Mineral Oil, Refrigerant, Water
- Temperature Range: -65° to 250° F
- Tubing: Use with seamless brass and copper
- Specifications Met:
Metric: SAE J512, SAE J513, UL Listed
All other fittings: SAE J512, UL Listed; except tee connectors for 1/2" tube OD
The flared end nests inside the fitting body, providing extra support to the tubing. Fittings are also known as inverted 45° flared fittings, refrigeration fittings, and SAE fittings. To assemble, place the nut (sold separately) on the tubing, flare the end of the tubing, then insert the tubing into the fitting and tighten the nut. Fittings are brass for good corrosion resistance.
