Pair these nuts with vibration-resistant compression sleeves and fittings for a strong seal on stainless steel tubing.

Create a strong seal on copper tubing when you couple these nuts with compression sleeves and fittings.

Pair these nuts with compression sleeves and high-pressure fittings. They withstand about twice as much pressure as nuts for standard compression fittings, so they’re good for hydraulic power applications.

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.
