Made of plastic, these sleeves create a strong seal without damaging tubing.

When used with high-pressure compression fittings and nuts, these sleeves bite into stainless steel tubing to form a strong seal.

Use these sleeves with compression nuts and fittings to create a strong seal on copper tubing.

Use these sleeves with Yor-Lok nuts and fittings to create an extra-strong seal on copper tubing.

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

Use these sleeves with a nut and fitting to provide a tight metal-to-metal seal on steel tubing that is flared to 37°.
