Quick-Disconnect Couplings for Plastic and Rubber Tubing—Chemicals
- For Use With: Ammonia, Ethanol, Phosphoric Acid (70%), Sodium Carbonate
- Temperature Range: 32° to 160° F
Couplings consist of a plug and a socket (sold separately) that join with a latch, so you can frequently connect and disconnect your line. To connect, insert the plug into the socket; to disconnect, press the latch on the socket and remove the plug. Plugs and sockets are polypropylene, which has excellent chemical, impact, and abrasion resistance.
Plugs and sockets with shut-off have a valve to stop the flow when the coupling is separated so fluid won’t spill from your line.
Note: For a complete coupling, order a plug and a socket with the same coupling size.

Barbed plugs insert into tubing and secure with a clamp.

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.

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. Attach one end to your hose and the other to a supply pipe or a second hose.
Aluminum couplings are lightweight and have good corrosion resistance.
316 stainless steel couplings have excellent corrosion resistance.
1 NPT couplings cannot be reconnected.
2 NPT and 3 NPT couplings have bolts designed to break before your hose does. They can be repaired with replacement bolt kits and replacement seal kits (both sold separately).
