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 Steel Threaded Pipe Flanges

These flanges are for low-pressure applications in noncorrosive environments.

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 Flanges

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

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
Steel Threaded Pipe Flanges

The galvanized finish on these Pressure Class 150 flanges provides fair corrosion resistance.

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.

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.

Aluminum Pipe and Pipe Fittings

Aluminum Unthreaded Pipe Flanges

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

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.

Low-Pressure Brass and Bronze Threaded Pipe and Pipe Fittings

Low-Pressure Brass and
Bronze Threaded Pipe Flanges

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

Low-Pressure Brass and
Bronze Threaded Pipe Fittings

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

Low-Pressure Brass Threaded
Pipe Fittings with Sealant

The male threads on these brass fittings have a sealant applied for extra protection against leaks. Also known as Pressure Class 125 fittings, they are built for use in low-pressure applications.

Low-Pressure Plated Brass Threaded Pipe Fittings

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.
