Stainless Steel Push-to-Connect Fittings for Food and Beverage
- Temperature Range: 0° to 240° F
- Tubing: Use with Nylon, PFA, Polyethylene, or TPU Plastic
- Specifications Met: FDA Compliant 21 CFR 177.1380, ISO 14743
Create corrosion-resistant connections in food and beverage lines with just a push. Also known as instant fittings, these fittings have an internal gripping ring and an O-ring that hold tight to tubing. To disconnect the fittings, push the release ring and pull the tubing out of the fitting. A smooth exterior with rounded edges prevents buildup of grime and contaminants for effective cleaning. With a 316 stainless steel body, they maintain their strength even when exposed to frequent washdowns and the harshest chemicals, including bleach, chlorine, and phosphoric acid. They’re also more durable than plastic fittings. FDA compliant, these fittings are approved for direct contact with food. Use them with low pressure and with firm or hard tubing only.

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.
