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.

FM-Approved Low-Pressure
Cast Iron Threaded Pipe Fittings

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.

Thick-Wall Galvanized Iron and Steel
Threaded Pipe Nipples and Pipe

Typically used with medium-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 80.

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.

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.

Iron and Steel Pipe Fittings with Flanged Ends

Bolt the flanged end of these fittings to another same-size flange, pump, or valve with a gasket to create an access point in a pipe line.

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.

Clamps for Easy-Access CPVC Pipe Fittings for Chemicals

Clamps for Easy-Access CPVC
Pipe Fittings for Chemicals

Use these clamps to connect easy-access CPVC pipe fittings and pipe.

Power Transmission

Base Mounting Plates for Right-Angle Speed Reducers

Mount right-angle speed reducers to machinery or other surfaces where access from the bottom is not possible.

Set Screw Flexible Shaft Couplings

Each hub includes a set screw (unless noted), which bites into your shaft to hold the coupling in place.

Machinable-Bore Flexible Shaft Couplings

Customize the bore of these flexible couplings to align uncommon shaft sizes as well as shafts that have become undersized from wear or oversized from coatings.

High-Speed Vibration-Damping Flexible Shaft Couplings

Use these gear-shaped couplings for high-speed and high-torque applications.

Vibration-Damping Flexible Shaft Couplings

A flexible tire on these couplings safeguards components on your shafts by reducing vibration and shock.

Splined-to-Keyed Flexible Shaft Couplings

Connect splined shafts to keyed shafts. These couplings are commonly used to connect hydraulic pumps, compressors, and other heavy duty equipment, which often have splined shafts, to electric motors and other components that often have keyed shafts.

Splined Flexible Shaft Couplings

For use with splined shafts, which are commonly found in gearboxes and pumps, these couplings are capable of transmitting more torque than couplings for round and keyed shafts.

Two-Piece Shaft Coupling Bridges

When your shafts are not close enough to use standard couplings, these have the length to bridge the gap.
