About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Push-to-Connect Tube Fittings for Drinking Water

BSPP Male Threads
with
Gasket

Temperature Range: 35° to 150° F
Tubing: See table
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.

NPTF (Dryseal) threads are compatible with NPT threads. BSPP male threads have a gasket to protect against leaks.

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.

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.

Through-Wall Straight Reducers, Tube

Through-wall fittings are also known as bulkhead couplings and panel-mount couplings; they mount through your wall or panel to create an inlet or outlet.
