Tight-Seal Brass Compression Tube Fittings for Air and Water
- Temperature Range: -65° to 250° F
- Tubing: Use with firm (Durometer 95A) EVA plastic or polyurethane rubber
- Specifications Met: SAE J512
A built-in tube support slips inside the tubing to prevent collapsing and provides a sturdy connection for an extra-tight seal. Fittings have a single sleeve (ferrule) that compresses the tubing as you tighten the nut. The nut and sleeve are included. Fittings are also known as flareless fittings. They are brass for good corrosion resistance.
