About Measuring Fittings

Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Plastic Push-to-Connect Tube Fittings for Chemicals

For Use With: Inch: Alcohol, 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. An internal gripping ring holds the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting. Use these fittings in low-pressure applications.

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 Tube Couplings for Chemicals

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.

Plugs, Male Threaded Pipe

For Use With: Ammonia, Ethanol, Phosphoric Acid (70%), Sodium Carbonate
Temperature Range: 32° to 160° F
