About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Metal Pipe and Pipe Fittings

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.

High-Pressure Iron and Steel Threaded Pipe Fittings

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

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.

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.

Low-Pressure Aluminum Threaded Pipe Flanges

Also known as Pressure Class 125 flanges, these are for use in low-pressure applications. Flanges are aluminum, which is lightweight with good corrosion resistance.

Aluminum Unthreaded Pipe Flanges

Use these unthreaded flanges in low-pressure applications. Also known as Pressure Class 125 flanges.

On/Off Valves

Flanged On/Off Valves for Fuel

Keep your worksite safe when working with diesel fuel, fuel oil, gasoline, and kerosene. Fire-tested to meet American Petroleum Institute (API) 607, these valves are designed to securely isolate fluid and prevent the spread of fire.

Tight-Seal Flanged Gradual On/Off Valves

A rubber-coated gate, also known as a resilient wedge, compresses against the valve seat to give these valves a tight, leakproof seal. Since they bolt onto flanges, they’re easier to install and remove than threaded and weld-on valves.

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.

Flanged Gradual On/Off Valves

Easier to install and remove than threaded or weld-on valves, these valves bolt to flanges. They open and close gradually, preventing system damage from sudden starts and stops in flow.
