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.

Low-Pressure Stainless Steel Threaded Pipe Fittings

Use these corrosion-resistant fittings in a low-pressure pipe line.

Premium Low-Pressure Stainless Steel
Threaded Pipe Fittings with Certification

Unlike other stainless steel fittings, these are made in the U.S.A. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition.

Low-Pressure Stainless Steel
Threaded Pipe Fittings with Sealant

The male threads on these fittings have a sealant applied for extra leak protection.

Standard-Wall Butt-Weld Stainless
Steel Unthreaded Pipe Fittings

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Low-Pressure Socket-Connect Stainless
Steel Unthreaded Pipe Fittings

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slip the pipe into the socket and weld.

Low-Pressure Press-Connect Stainless
Steel Unthreaded Pipe Fittings

Press these fittings onto stainless steel pipe using a crimping tool for a permanent, leak-tight connection that's faster than threading or welding and doesn't require heat.

Iron and Steel Pipe and Pipe Fittings

Standard-Wall Butt-Weld Steel
Unthreaded Pipe Fittings

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Low-Pressure Press-Connect
Steel Unthreaded Pipe Fittings

Crimp these fittings onto steel pipe to form a tightly sealed connection that’s faster than threading or welding and doesn’t require heat.

Low-Pressure Iron and Steel Threaded Pipe Fittings

Use these fittings for low-pressure applications in noncorrosive environments.

Low-Pressure Iron and Steel
Threaded Pipe Fittings with Sealant

To prevent leaks in low-pressure lines, the male threads on these fittings have an acrylic sealant already applied for extra protection.

FM-Approved Low-Pressure
Cast Iron Threaded Pipe Fittings

Suitable for use in fire-protection applications, these pipe fittings are made of cast iron, so they are brittle and can be quickly opened with the strike of a sledge hammer.

Low-Pressure Galvanized Iron
and Steel Threaded Pipe Fittings

The galvanized finish on these fittings provides fair corrosion resistance. Fittings are for use in low-pressure applications.

Low-Pressure Galvanized Iron and Steel
Threaded Pipe Fittings with Sealant

The male threads on these fittings have a sealant applied for extra leak protection.

FM-Approved Iron Pipe Fittings with Flanged Ends

FM approved, these fittings are suitable for use in fire-protection systems. All have flat-surface flanged ends that only mate to another same-size flat-surface flange, pump, or valve with a gasket to create an access point in a pipeline.

Brass and Bronze Pipe and Pipe Fittings

Low-Pressure Brass and
Bronze Threaded Pipe Fittings

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

Low-Pressure Brass Threaded
Pipe Fittings with Sealant

The male threads on these brass fittings have a sealant applied for extra protection against leaks. Also known as Pressure Class 125 fittings, they are built for use in low-pressure applications.

Low-Pressure Plated Brass Threaded Pipe Fittings

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.

Bronze Unthreaded Pipe Fittings

Also known as Silbraze fittings.

Aluminum Pipe and Pipe Fittings

Standard-Wall Butt-Weld Aluminum
Unthreaded Pipe Fittings

Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings.

Low-Pressure Aluminum Threaded Pipe Fittings

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

Medium-Pressure Aluminum Threaded Pipe Fittings

Designed for medium-pressure applications, these fittings have better strength than our low-pressure aluminum pipe fittings.

Copper-Nickel Threaded Pipe Fittings

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

Plastic Pipe and Pipe Fittings

Standard-Wall Plastic Pipe Fittings for Water

Connect these fittings to Schedule 40 plastic pipe—they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.

Clear-View Standard-Wall
Plastic Pipe Fittings for Water

Watch water flow through your line. These fittings are compatible with Schedule 40 pipe, the industry standard for residential and commercial low-pressure plumbing and water supply.

UV-Resistant Standard-Wall
PVC Pipe Fittings for Water

Connect these fittings to UV-resistant PVC pipe. Designed for outdoor use, they contain an additive that protects against the damaging effects of ultraviolet light. Fittings are typically used in low-pressure residential and commercial plumbing and water supply applications up to 300 psi.

Drain, Waste, and Vent ABS
Pipe Fittings for Chemicals

These fittings are an economical option for chemical waste systems. Fittings are ABS plastic, which has excellent strength and impact resistance and good chemical resistance.

Drain, Waste, and Vent ABS
Pipe Flanges for Chemicals

Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges are an economical option for gravity-flow chemical waste systems. They are ABS plastic, which has excellent strength and impact resistance and good chemical resistance.

Gravity-Flow CPVC Pipe Fittings
for Corrosive Chemical Waste

These fittings are NSF certified for use in corrosive waste gravity-flow systems. Made of CPVC, they have better chemical resistance than ABS plastic gravity-flow fittings and can stand up to highly-corrosive acids and other harsh substances.

Gravity-Flow Polypropylene Pipe
Fittings for Corrosive Chemical Waste

Made of polypropylene, these gravity-flow fittings withstand organic solvents, such as acetone, that would dissolve CPVC pipe. They also stand up to highly corrosive acids, such as hydrochloric acid, and alkalies.

Aboveground Standard-Wall PVC Pipe
Fittings for Drain, Waste, and Vent

These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

Aboveground Standard-Wall PVC Pipe
Flanges for Drain, Waste, and Vent

Bolt two same-size flanges together with a gasket to create an access point within a line. Also known as Schedule 40 flanges, they are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

Fittings for Rigid PVC Conduit

Connectors for Rigid PVC Conduit

Join pieces of conduit.

Access Ports for Rigid PVC Conduit

Also known as conduit bodies, these ports provide access to wire and cable inside PVC conduit for pulling, splicing, and maintenance. They are also used to change the direction of a run.
