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.

Metal Barbed Hose Fittings for Chemicals and Petroleum
Made of stainless steel, these fittings stand up to a wide variety of chemicals, as well as fuels, gasoline, and oils. To connect, slide the barbed end into plastic or rubber hose and secure with a clamp.
Adapters are also known as hose nipples; they adapt a barbed end to a threaded end.

- Maximum Pressure: 300psi @ 72° F
- Temperature Range: -30° to 200° F
- Attachment Type: Use Band-and-Buckle Clamps
On/Off Valves with Push-to-Connect Fittings for Chemicals

Push to Connect
Insert tubing into the fittings on these valves—no heat, solder, or flux required. To withstand aggressive and corrosive solutions, they have a chemical-resistant fluoroelastomer seal and a plastic body.
Full-port valves do not restrict flow.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
