Push-to-Connect Tube Fittings for Drinking Water
- Temperature Range: 35° to 150° F
- Tubing: Use with firm or hard nylon or polyethylene plastic
- Specifications Met: NSF/ANSI 61
Made of moisture-resistant acetal, these fittings won't absorb water and lose strength, even in high-humidity environments. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting. All meet NSF/ANSI 61 for use in drinking water systems.

Tube supports are recommended if you want to use fittings with soft nylon, polyethylene, and PVC tubing to prevent the tube from collapsing.
Plastic Push-to-Connect Tube Fittings for Chemicals
- For Use With: Alcohol, Hydrochloric Acid, Nitric Acid, Sodium Carbonate, Sulfuric Acid
- Temperature Range: 0° to 270° F
- Tubing: Use with hard (Durometer 55D-60D) FEP plastic
Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting. Fittings are PVDF (also known as Kynar), which offers excellent chemical resistance and can handle higher temperatures 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.
