Tight-Seal Moisture-Resistant Plastic Barbed Tube Fittings for Air and Water
- Temperature Range: -20° to 280° F
- Tubing: Use with firm or soft (Durometer 50A-90A) polyurethane rubber or PVC plastic
- Specifications Met: FDA Compliant 21 CFR 177.2470
Fittings have a single barb that creates a smooth clamping surface for extra-tight connections that minimize leaks. Made of acetal, they won’t absorb water and lose strength, even in high-humidity environments.
