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.
