Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
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. NPTF (Dryseal) threads are compatible with NPT threads.

Nuts for Compression Fittings for Copper Tubing
Use these nuts with compression sleeves and fittings to create a strong seal on copper tubing. They are brass for good corrosion resistance.
Long nuts support more of the tube’s surface area than short nuts for a strong grip in high-vibration applications.
Nuts with a built-in sleeve (ferrule) help ensure the sleeve is positioned correctly for installation.

- For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil, Water
- Temperature Range: -65° to 250° F, except metric fittings are -40° to 250° F
- Tubing: Use with copper
- Specifications Met: UL listed, except for metric fittings

45° Flared Fittings for Copper and Brass Tubing


(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.
NPTF (Dryseal) threads are compatible with NPT threads.
Metric and UN/UNF (Straight) threads have a gasket to protect against leaks. 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.
