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.

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.

FM-Approved Low-Pressure
Cast Iron Threaded Pipe Flanges

Suitable for use in fire-protection applications, these flanges are brittle and can be quickly opened with the strike of a sledge hammer.

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.

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.

FM-Approved Low-Pressure Cast
Iron Unthreaded Pipe Flanges

FM-approved for fire protection applications, these flanges are cast iron, so they're brittle and can be quickly opened by hitting them with a sledge hammer.

Grooved-End Iron Pipe Fittings

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

Standard-Wall Grooved-End
Steel Pipe Nipples and Pipe

This steel pipe has grooved ends that connect to fittings with a clamp (sold separately) for an easy way to install piping systems.

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.

High-Purity PVDF Pipe Fittings
for Corrosive Chemicals

Made of PVDF that’s finished to a 12 Ra smoothness, these fittings handle some of the harshest chemicals without leaching contaminants into your line. Comparable to Kynar, they handle most organic solvents that would dissolve CPVC, and chlorine or nitric acid that would weaken polypropylene.

High-Purity PVDF Pipe for Corrosive Chemicals

Made of PVDF that’s finished to a 12 Ra smoothness, this pipe handles some of the harshest chemicals without leaching contaminants into your line.

On/Off Valves

Threaded On/Off Valves

Use these valves in general purpose applications, such as those with water, oil, air, and inert gas.

Flow-Indicating Threaded On/Off Valves

An easy-to-read flow-indicating handle shows the percentage the valve is open. These valves are for use with water, oil, inert gas, and steam.

Threaded On/Off Valves for Drinking Water

For use in drinking water systems, these valves meet NSF/ANSI 61.

FM-Approved Threaded Gradual On/Off Valves

FM-approved for fire suppression and protection, these valves can isolate sections of the water supply in your facility.

Flexible Joint Gradual On/Off Valves

Flexible joints keep these valves tightly sealed during pressure changes or vibrations from heavy machinery.

FM-Approved Flanged Gradual On/Off Valves

FM-approved, these valves are often used to isolate sections of your facility’s water supply for fire suppression and protection.

Solenoid On/Off Valves for Natural
Gas, Propane, and Butane

Install these valves in gas pipelines to automatically control the flow of natural gas, propane, and butane to equipment.

Fire Protection

Fire Hydrants

Fight fires in areas around your facility that city-installed hydrants don’t reach.

Fire Post Indicators

Open and close water supply valves for fire systems that are buried underground or in a wall.

Pipe Wrenches

Nonsparking Nonmarring Pipe Wrenches

Made of aluminum-bronze that is Factory Mutual approved, these wrenches inhibit sparking and are nonmagnetic and corrosion resistant. They are also known as railroad wrenches.

Nonsparking Pipe Wrenches

Made of materials that are Factory Mutual approved, these wrenches inhibit sparking and are nonmagnetic and corrosion resistant.
