About Measuring Fittings

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

Barbed Fittings for Plastic and Rubber Tubing—Chemicals

For Use With: Alcohol, Coolant, Mild Bases
Temperature Range: See table
Tubing: Use with firm (Durometer 75A-80A) polyurethane rubber, PVC plastic, or Viton® fluoroelastomer rubber

Minimize leaks in your line—these fittings have a single barb that creates a smooth clamping surface for extra-tight connections. Fittings are polypropylene, which has very good chemical resistance as well as impact and abrasion resistance.
