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.
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.

- For Use With:
NPTF Threads: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Mineral Oil, Refrigerant, Water
BSPT Threads: Air, Cutting Oil, Diesel Fuel, Mineral Oil, Refrigerant, Water

Nuts for 45° Flared Fittings for Copper and Brass Tubing
- 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.

Low-Strength Steel Coupling Nuts
Also known as extension nuts, use these to connect and extend threaded rods. They're about half the strength of medium-strength steel coupling nuts for use in light duty fastening applications.
Zinc-plated steel coupling nuts resist corrosion in wet environments.

High-Strength Steel Coupling Nuts—Grade 8
Also known as extension nuts, use these to connect and extend threaded rods. Made from Grade 8 steel, they're about 25% stronger than medium-strength steel coupling nuts. A zinc plating provides corrosion resistance in wet environments.

Rod Alignment Couplers
Increase cylinder life by fixing alignment problems between air or hydraulic cylinders and driven components. Couplers have a threaded end that moves to compensate for the angle of misalignment, reducing wear on cylinder bearings and seals. Couplers have a male and female end.

Hitch Balls
Mount these onto a hitch insert, and connect them to a trailer with a hitch-ball coupler. Maximum trailer weight is the total weight being towed.
