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.

Temperature Range: 32° to 200° F

Solder these fittings to copper tubing or the tube end of another fitting for a permanent, leak-tight connection. They are also known as sweat fittings. Fittings have good corrosion resistance. To adhere to safety standards for drinking water systems, use fittings that meet NSF/ANSI 61 or EN 1057.

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

Cleaned and Bagged Solder-Connect Fittings for Copper Tubing

For Use With: Drinking Water
Temperature Range: 32° to 200° F
Tubing: Use with K, M, L copper
Specifications Met: ASME B16.22, MSS-SP104, NSF/ANSI 61

When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination. Solder the socket end to copper tubing or the tube end of another fitting for a permanent, leak-tight connection. They are also known as sweat fittings. Fittings have good corrosion resistance. They meet NSF/ANSI 61 safety standards for use with drinking water systems.

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

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.

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
