About Pipe and Fittings

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

Chemical and Petroleum Hose Fittings

International Standard ISO Minimal-Spill
Quick-Disconnect Hose Couplings for Chemicals

To minimize fluid loss when connecting and disconnecting your line, these couplings have flat faces for a close fit and shut-off valves to stop the flow—they meet ISO 16028, which is an international standard for hose couplings.

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.

Cleaned and Bagged Metal Barbed
Hose Fittings for Chemicals

Each of these metal fittings is double bagged to prevent contamination in areas that require a high level of cleanliness.

Breakaway Hose Couplings
for Chemicals and Petroleum

Minimize chemical and petroleum spills during accidental disconnects, such as a driver pulling away during loading. These couplings have a shut-off valve on each half to stop flow when they’re separated.

Screw-On Hose Fittings for D.O.T. Hose

Create or repair D.O.T. hose assemblies in the field with just a wrench and a vise, no crimper required.

Coolant Hose Fittings

Quick-Disconnect Hose Couplings for Coolant

Couplings consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are designed for coolant applications up to 200 psi. Also known as coolant-line mold couplings.

Barbed Hose Fittings for Coolant

Designed for coolant applications up to 200 psi, these fittings have a standard barbed end that slides into hose and secures with a clamp.

Beaded Hose Fittings for Coolant

A single rounded bead grips onto hose just like a barb, but has no sharp edges that could cut or damage soft hose. Slide the beaded end into hose and secure with a clamp. Use in coolant applications up to 300 psi.

Minimal-Spill Quick-Disconnect
Hose Couplings for Coolant

Reduce the risk of spills near electronics when connecting and disconnecting liquid cooling lines. Also known as double shut-off couplings, these couplings have a shut-off valve on both sides that stops the flow of coolant if they’re separated.

Tubing and Tube Fittings

High-Flow Quick-Disconnect
Tube Couplings for Chemicals

A spring-free flow path allows more chemicals to pass through these tube couplings at lower line pressures than other quick-disconnect couplings.
