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

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

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

These fittings include a nut with a built-in sleeve, so there’s no need to remove the nut for assembly.

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.

Often used in outdoor, damp, and washdown environments, these 316 stainless steel fittings will not corrode from water, salt, or chemicals. The male threaded ends mate with NPT, NPTF, BSPT, BSPP, and other universal threads, so you won’t have to worry about matching exact threads when you’re on the job.

A built-in tube support slips inside the tubing to prevent collapsing and provides a sturdy connection for an extra-tight seal.

These fittings include a nut with a built-in sleeve (ferrule), so there’s no need to remove the nut for assembly.

Lighter in weight than their metal counterparts, these compression fittings are polypropylene.

Not only are these chrome-plated brass couplings corrosion resistant, they’re also durable enough to handle pressures up to 250 psi and can be used with vacuum.

These plastic compression fittings meet NSF/ANSI Standard 51 for food contact.
