These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

Combine an adapter with a two-piece pipe flange (sold separately) to build a customized flange connection for noncorrosive environments.

Also known as Code 61 SAE hydraulic 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, 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.

These fittings are made to tighter tolerances than other stainless steel pipe fittings. They are also known as instrumentation fittings.

Also known as Code 61 SAE hydraulic flanges.

Also known as Pressure Class 150 flanges, these corrosion-resistant flanges are designed for low-pressure pipe applications.

Use these heavy duty forged flanges for high-pressure applications.

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.

Also known as Pressure Class 150 flanges, these brass flanges are designed for low-pressure applications.

Bolt these flanges to another same-size flange with a gasket to create an access point within a pipe line. They are also known as Silbraze flanges.
