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.

Stainless Steel Bleed Rings

Create an access point in systems where corrosion is a concern. Made of stainless steel, these bleed rings resist rusting.

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.

Steel Bleed Rings

Access the inside of lines, so you can vent pressure, drain liquid, or take samples. Made of black-coated steel, these bleed rings should be used in dry environments to prevent rusting.

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.

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.

Low-Pressure Galvanized
Steel Threaded Pipe Flanges

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

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 Aluminum Threaded Pipe Fittings

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

Medium-Pressure Aluminum Threaded Pipe Fittings

Designed for medium-pressure applications, these fittings have better strength than our low-pressure aluminum 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.

Expansion Joint Reducers with Flanged Ends

Connect different pipe sizes in your line while adding a point of flexibility between them. These expansion joints absorb movement between two connected pipes to reduce stress, vibration, and noise.

Quick-Clamp High-Vacuum
Fittings for Aluminum Tubing

For use in high-vacuum systems, these fittings use a metal reinforced O-ring to create an airtight seal. Also known as KF, QF, and NW fittings, they’re used for high-vacuum applications such as vacuum coating and heat treating, leak testing, and analyzing gases.

Metal Cam-and-Groove Hose
Couplings for Chemicals and Petroleum

Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

Minimal-Spill Push-and-Turn
Hose Couplings for Chemicals

Quickly connect and disconnect hose lines used with a variety of chemicals, from adhesives to isopropyl alcohol and ink. Any part of these couplings that contacts fluid is made from 316 stainless steel, C-276 Hastelloy, PTFE, or fluoroelastomer to withstand the chemicals in your line.

Metal Cam-and-Groove Hose Couplings for Water

Metal cam-and-groove couplings have better durability than plastic cam-and-groove couplings.
