Create a strong connection without heating, flaring, or soldering.

With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings.

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

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

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal.

Use these sleeves with compression nuts and fittings, sometimes called bite fittings, to create a strong seal on steel tubing. They are also known as ferrules.

Thicker walls make these fittings—sometimes called flareless or bite fittings—withstand about twice as much pressure as standard compression fittings, so they’re good for hydraulic power applications.
