Sleeves for Quick-Assembly Brass
Compression Tube Fittings for Air and Water
- Temperature Range: 0° to 150° F
- Tubing: Acetal plastic sleeves: Use with (firm or hard) polyethylene plastic or polypropylene plastic
Brass sleeves: Use with (firm or hard) nylon plastic, polyethylene plastic or polypropylene plastic
Use these to replace a damaged sleeve (ferrule) in quick-assembly brass compression nuts.
Acetal sleeves are softer than brass, so they won’t damage your tubing.
