How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Plastic Barbed Tube Fittings for Air and Water

Fittings have barbs that grip onto tubing.

Nylon fittings have excellent impact and abrasion resistance.

Barbed Fittings for Plastic and Rubber Tubing—High-Purity

For Use With: Beverage, Food
Temperature Range: -80° to 220° F
Tubing: Use with soft or firm (Durometer 50A-80A) plastic blend, polyethylene plastic, polyurethane rubber, PVC plastic, or silicone rubber
Specifications Met: FDA Compliant 21 CFR 177.2510, FDA Compliant 21 CFR 177.1520

Fittings have a single barb that creates a smooth clamping surface for extra-tight connections that minimize leaks. Designed for high-purity applications, they are produced in a clean room and are double bagged to prevent dirt and moisture from contaminating the inside. Fittings are PVDF (also known as Kynar), which has excellent strength.
