Couplings are plastic, which is lighter in weight than metal 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.

Made of plastic, these fittings are lighter in weight than metal barbed fittings, yet have the chemical and corrosion resistance to stand up to harsh substances. Slide the barbed end into plastic or rubber hose and secure with a clamp.

To stand up to the harsh chemicals used to clean food-processing lines, these fittings are made of PVDF, also known as Kynar.

No need for a gasket—this hose’s PTFE liner flares out as it passes through the flanges, so your line’s contents never touch the fittings.

Adjust the flow while dispensing liquid chemicals.

Quick-disconnect couplings consist of a plug and a socket that join with a latch so you can easily connect and disconnect your line.

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on stainless steel tubing that is flared to 37°.

The male pipe threads on these fittings have a sealant applied for extra protection against leaks.

Also known as manifold flange fittings, these have a clamp-together design that lets you access your line for routine maintenance. Fittings resist acids, solvents, and other harsh chemicals. They won’t deteriorate when exposed to the damaging effects of ultraviolet light, so they’re suitable for outdoor use.
