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
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.
UN/UNF (SAE Straight) threads are also known as O-ring boss threads.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
- For Use With: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Mineral Oil, Refrigerant, Water
- Specifications Met: SAE J512, SAE J513, UL Listed
Fittings that swivel until tightened rotate 360° for easy installation.

Compression Fittings for Copper Tubing
- Temperature Range: See Table
Create a strong connection without heating, flaring, or soldering. These fittings have a single sleeve (ferrule or olive) that bites into tubing as you tighten the nut. Both the nut and sleeve are included. Also known as single ferrule fittings, they are easier to install than yor-lok fittings which have two ferrules. They’re often used in low to medium pressure applications, such as plumbing and compressed air systems, which don’t require the strength of a yor-lok fitting. Compression fittings for copper tubing can withstand higher pressures than compression fittings for plastic and rubber tubing. Made of brass, they have good corrosion resistance.
To connect a compression fitting to tube, slide the nut and sleeve onto the tube. Then push the tube into the fitting until it butts against the back of the fitting. Tighten the nut onto the fitting to compress the sleeve.
Threaded connections can be taken apart as needed for maintenance and repair.

Bend-and-Stay Positioning Arms
Stronger and with greater load capacities than gooseneck-style positioning arms, these arms keep their shape even when moving or when exposed to vibration. They’re often used in robotics and conveyor applications when frequent repositioning isn’t required.
