Nuts with Built-In Sleeve for Quick-Assembly
Compression Fittings for Copper Tubing
- For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil, Water
- Temperature Range: -65° to 250° F
- Tubing: Use with copper
Use these nuts with quick-assembly compression fittings to create a strong seal on copper 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 are brass for good corrosion resistance.

Nuts with Built-In Sleeve for Plastic Compression Tube Fittings for Water
- Temperature Range: -40° to 200° F
- Tubing: Use with hard (Durometer 0D-75D) nylon plastic or polypropylene plastic
Use these nuts with plastic 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. Nuts are moisture-resistant acetal, so they won't absorb water and soften, even in high-humidity environments.

Nuts with Built-In Sleeve for Plastic Compression Tube Fittings for Air
- For Use With: Air, Lubricated Air
- Temperature Range: -30° to 210° F
- Tubing: Use with firm or hard nylon plastic, polyethylene plastic or polypropylene plastic
Use these nuts with plastic 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. Nuts are polypropylene, which has excellent impact and abrasion resistance.

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. Nuts are PVDF (also known as Kynar), which has excellent strength and can handle high temperatures up to 270° F.
