How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Plastic Push-to-Connect Tube Fittings for Chemicals
- For Use With: Inch: Acetic Acid, Alcohol, Arsenic Acid, Benzoic Acid, Fluoboric Acid, Hydrochloric Acid, Nitric Acid, Sodium Carbonate, Sulfuric Acid
Metric: Acetic Acid, Alcohol, Arsenic Acid, Benzoic Acid, Fluoboric Acid, Sodium Carbonate, Sulfuric Acid - Temperature Range: Inch: 0° to 270° F
Metric: 32° to 175° F - Tubing: Use with hard (Durometer 55D-60D) FEP plastic
Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push, and an internal gripping ring and fluoroelastomer O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting.
PPS fittings resist a wide variety of chemicals, although are not for use with hydrochloric acid or nitric acid. They withstand temperatures up to 175° F.
PVDF fittings offer excellent chemical resistance, and can be used with hydrochloric acid and nitric acid. They withstand temperatures up to 270° F, higher than other push-to-connect fittings for chemicals. They are produced in a clean room and are bagged individually to prevent dirt and moisture from contaminating the inside. PVDF is also known as Kynar.
NPTF (Dryseal) threads are compatible with NPT threads.

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.
