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.

Medium-Pressure Pipe Fittings
for Joining Dissimilar Metals

Use these unions to connect different metals in a piping or plumbing system. They have a gasket with a plastic sleeve that inhibits destructive corrosion.

Copper-Nickel Threaded Pipe Fittings

These fittings have excellent resistance to stress cracking and have better corrosion resistance than most stainless steel alloys.

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 Butt-Weld Pipe Fittings

Also known as Pressure Class 200 fittings.

Copper-Nickel Unthreaded Pipe

Also known as Pressure Class 200 pipe.

Thick-Wall Plastic Pipe Fittings for Water

Connect these fittings to thick-wall plastic pipe—they have thicker, stronger walls than standard-wall fittings, so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. They can withstand pressures up to 900 psi.

Low-Pressure Clamp-On Connectors

Low-Pressure Clamp-On Connectors
for Drain, Waste, and Vent

To make installing and maintaining systems easy, these connectors come with clamps that form a strong seal on pipe and fittings once tightened.

Low-Pressure Clamp-On Connectors for Water

Also known as no-hub couplings, these have a one-piece sleeve with a stop in the center, so you know your pipe is always aligned correctly.

Low-Pressure Quick-Lock
Clamp-On Connectors for Air

A turn of the T-handle will tighten and loosen these connectors, so you can quickly disassemble and reassemble your lines without tools.

Low-Pressure Clamp-On Connectors for Air

These connectors are for use in low-pressure air and vacuum conveying systems, as well as in gravity-flow systems.

Pipe Repair Clamps

Low-Pressure Pipe Repair Clamps

Use in low-pressure applications up to 150 psi.

Medium-Pressure Pipe Repair Clamps

Use in medium-pressure applications up to 600 psi.

Pipe Joint Repair Clamps

Stop leaks where a fitting and a pipe join without turning off your line.

High-Pressure Pipe Repair Clamps

Use in high-pressure applications up to 1,000 psi.

Low-Pressure Easy-Install Pipe Repair Clamps

Snap these clamps around leaking pipe with only your hands. No tools required.

Tube Fittings for Copper and Brass Tubing

Solder-Connect Fittings for Copper Tubing

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

Cleaned and Bagged Solder-Connect
Fittings for Copper Tubing

When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination.

Press-Connect Fittings for Copper Tubing

Crimp these fittings to copper tubing with a crimping tool for a leak-tight connection that doesn’t require heat or soldering. They are comparable to Viega ProPress fittings.

Crimping Tools for Press-Connect
Fittings for Copper Tubing

Create a leak-tight seal without using heat or solder. Slide copper tubing into a press-connect fitting and use these tools to crimp the connection.

Compression Fittings for Copper Tubing

Nickel-Plated Brass Compression
Fittings for Copper Tubing

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

Precision Compression Fittings for Copper Tubing

Also known as instrumentation fittings, these are made to tighter tolerances than standard compression fittings. They are compatible with Parker CPI fittings.

Sleeves for Precision Compression
Fittings for Copper Tubing

Quick-Assembly Compression
Fittings for Copper Tubing

These fittings include a nut with a built-in sleeve, so there’s no need to remove the nut for assembly.

Vibration-Resistant Compression
Fittings for Copper Tubing

The sleeve in these fittings is rubber instead of metal, so it cushions the tubing and absorbs vibration while creating a tight seal.

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.

Brass Push-to-Connect Fittings for Copper Tubing

Choose these metal fittings when you need better durability than our plastic push-to-connect fittings.

Plastic Push-to-Connect Fittings for Copper Tubing

Made of plastic, these fittings are lightweight compared to our brass push-to-connect fittings.

Yor-Lok Fittings for Copper Tubing

Repair Clamps for Copper Tubing

Repair leaks in copper tubing.
