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 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.

High-Pressure Iron and Steel Threaded Pipe Fittings

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

Medium-Pressure Iron and
Steel Threaded Pipe Fittings

For use in noncorrosive environments, these fittings have better strength than our low-pressure iron and steel pipe fittings.

Medium-Pressure Galvanized Iron
and Steel Threaded Pipe Fittings

A galvanized finish gives these fittings fair corrosion resistance. They have the strength to handle medium-pressure applications.

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.

Grooved-End Iron Pipe Fittings

The grooved ends on these iron fittings connect to pipe with a clamp to easily install piping systems.

Drain, Waste, and Vent Iron Pipe Fittings

Also known as no-hub pipe fittings and soil pipe fittings, these fittings are for use in gravity-flow applications both above and below ground.

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

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.

Conduit and Fittings

Adapters for Medium-Wall (IMC)
and Thick-Wall (Rigid) Steel Conduit

Attach conduit to a knockout in an outlet box or enclosure.

Access Ports for Metal Conduit

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

Fittings for Liquid-Tight Flexible Metal Conduit

These fittings seal out liquids when connecting liquid-tight flexible metal conduit to a knockout in an outlet box or enclosure.

Adapters for Flexible Metal Conduit

Attach conduit to a knockout in an outlet box or enclosure.
