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.

Standard-Wall Galvanized Steel Pipe Nipples
and Pipe for Joining Dissimilar Metals

A plastic sleeve prevents destructive corrosion when connecting different metals.

Standard-Wall Copper-Nickel
Threaded Pipe Nipples and Pipe

Also called close nipples, these Schedule 40 nipples are threaded on both ends to the center.

Copper-Nickel Unthreaded Pipe

Also known as Pressure Class 200 pipe.

Solder-Connect Fittings for Copper Tubing

Solder these fittings to tubing for a permanent, leak-tight connection. They are also known as sweat fittings.

45° Flared Fittings for Copper and Brass Tubing

No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They are also known as refrigeration and SAE fittings.

Supported 45° Flared Fittings
for Copper and Brass Tubing

The flared end of the fitting nests inside the fitting body, providing extra support to the tubing. Fittings are also known as inverted 45° flared fittings.

37° Flared Fittings for Copper Tubing

Also known as JIC (Joint Industrial Council) fittings, these connect to tubing that is flared to 37°. They can handle higher pressures than 45° flared fittings.

Yor-Lok Fittings for Copper Tubing

A nut with two sleeves (ferrules) gives these fittings extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal.

Nickel-Plated Brass Compression
Fittings for Copper Tubing

With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings.
