Nuts with Built-In Sleeve for Quick-Assembly Brass
Compression Tube Fittings for Air and Water
- Tubing: Use with firm or hard nylon plastic, polyethylene plastic or polypropylene plastic
- Temperature Range: 0° to 150° F
Use these nuts with quick-assembly brass compression fittings to create a seal on plastic tubing. They have a built-in sleeve (ferrule), so the sleeve is positioned correctly for installation. Thread the nut onto the fitting, then insert the tubing and tighten the nut. They have good corrosion resistance.
Acetal sleeves are softer than brass, so they won’t damage your tubing.

Nuts with Built-In Sleeve for High-Temperature
Compression Tube Fittings for Food and Beverage
- Temperature Range: -40° to 270° F
- Tubing: Use with firm or hard (Durometer 45D-65D) nylon plastic, polyethylene plastic, or polypropylene plastic
- Specifications Met: FDA Compliant 21 CFR 177.2510, NSF/ANSI 51, NSF/ANSI 61, USP Class VI
Use these nuts with high-temperature compression fittings for food and beverage to create a seal on plastic tubing. They have a built-in sleeve (ferrule), so the sleeve is positioned correctly for installation. Thread the nut onto the fitting, then insert the tubing and tighten the nut.
