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 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.
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.

Nuts for 45° Flared Fittings for Copper and Brass Tubing
Short Nut
Long Nut
- For Use With: Cutting Oil, Fuel Oil, Refrigerant, Mineral Oil, Diesel Fuel, Water, Air
- 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
Use these nuts with 45° flared tube fittings to provide a tight metal-to-metal seal on flared copper and brass tubing. Nuts are brass for good corrosion resistance. They don’t require a sleeve, which makes for a fast, convenient installation.
Long nuts support more of the tube’s surface area than short nuts for a strong grip in high-vibration applications.

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.
NPTF (Dryseal) threads are compatible with NPT threads.
