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.

Fittings with intermittent swivel rotate 360° before and after installation as needed to allow movement in the system and to prevent kinking.
Inline tees are also known as branch tees.
Right-angle tees are also known as run tees.

Compression Fittings for Plastic Tubing—Chemicals
- For Use With: PFA Plastic: Hydrochloric Acid, Sulfuric Acid
PTFE Plastic: Alcohol, Ammonia, Benzoic Acid, Bleach, Bromine, Coolant, Fluoboric Acid, Hydrochloric Acid, Hydrofluoric Acid, Nitric Acid, Organic Solvents, Sodium Carbonate, Sulfuric Acid - Temperature Range: PFA Plastic: 0° to 350° F
PTFE Plastic: -40° to 185° F - Tubing: PFA Plastic: Use with hard (Durometer 50D-65D) PFA or PTFE plastic
PTFE Plastic: Use with hard (Durometer 60D) PFA or PTFE plastic
A sleeve (ferrule) compresses the tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. Fittings are also known as flareless fittings. Fittings that include a gripper sleeve on the tubing create an even tighter seal.
PTFE fittings are highly resistant to most acids, alcohols, detergents, and solvents. They’re made by machining. Their nut is made of PVDF, which is resistant to halogens such as chlorine and bromine, strong acids such as hydrofluoric and nitric acids, and organic solvents.
