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. Tough enough to handle frequent use, these couplings are designed to be virtually spill free. Also known as dry disconnects and double-shut off couplings, both the plug and the socket have a shut-off valve that stops the flow of liquids when they’re separated. To connect, push the plug into the socket and lock with a quarter turn. The socket swivels, so you won’t have to twist your hose to attach the plug. It also has a rubber lip and large handles to prevent damage if it’s dropped.
A complete coupling consists of a plug and a socket (both sold separately). They’re compatible with MannTek, Avery Hardoll, Todo-matic, and other dry-disconnect couplings that meet NATO standard STANAG 3756.
Aluminum couplings are lighter in weight than stainless steel and have good corrosion resistance.
316 stainless steel couplings have excellent corrosion resistance.

High-Temperature Nickel Tubing
- Temperature Range: -320° to 1200° F
- Bending Method: Tube Bender
Also known as Inconel, this tubing has the highest temperature rating of all the non-stainless steel tubing we offer. It has excellent corrosion and chemical resistance. It’s also seamless—the smooth interior won’t restrict flow. You can flare the ends without splitting the tubing, and weld to connect. All sizes meet ASTM B163, which is an international standard for tubing dimensions.
