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

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

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.

These fittings have two sleeves for extra gripping power. They bite into steel tubing as you tighten the nut to form a strong seal.

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

The external hex bolt on these fittings allows for easy installation in cramped spaces.

A tube adapter sits flush against the flat face of the fitting so you can slide the steel tubing and fitting sideways to disconnect in cramped spaces. Also known as zero-clearance fittings.

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

These fittings have the highest pressure rating of all the Yor-Lok tube fittings we offer.

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

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

Individually bagged to prevent contamination, these fittings are suitable for applications that require a high level of cleanliness.

The male pipe threads on these fittings have a sealant applied for extra protection against leaks.

The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings.

Polished to at least a 15 Ra finish on the inside, these fittings have an ultra-smooth interior surface that helps prevent contamination. They are also known as ultra-high-purity fittings.

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

Also known as instrumentation fittings, these are made to tighter tolerances than standard compression fittings. They are compatible with Parker CPI fittings.

Also known as JIC (Joint Industrial Council) fittings, these connect to tubing that is flared to 37°. They can handle higher pressures than 45° flared fittings.

No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They are also known as refrigeration and SAE fittings.

These Monel fittings have the corrosion resistance to handle hydrofluoric and sulfuric acid. Also known as instrumentation fittings, they include a nut with two sleeves.

Also known as JIC (Joint Industrial Council) fittings, these provide a tight seal on tubing that is flared to 37°.
