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.
Straight Reducers, Tube Stem × Tube Stem
Fittings with tube stem insert into the push-to-connect end of another fitting in place of a length of tubing.
