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.
For technical drawings and 3-D models, click on a part number.
Barbed plugs insert into tubing and secure with a clamp.
