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.
PFA fittings stand up to harsh substances. They’re made through a melting process. 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.
