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

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.

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

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.

The flared end of the fitting nests inside the fitting body, providing extra support to the tubing. Fittings are also known as inverted 45° flared fittings.

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

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

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

Make lightweight connections without the hassle of matching the exact thread type—these fittings connect to NPT, NPTF, BSPP, BSPT, and other universal threads.

These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications.

A single sleeve (ferrule) compresses the tubing as you tighten the nut on these fittings, creating a strong seal. They are brass for good corrosion resistance.

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

Made of acetal, these compression fittings are lighter in weight than metal compression fittings and won’t absorb moisture when used in wet environments.

Fittings have a sleeve that bites into tubing as you tighten the nut to form a seal in applications up to 120 psi. Also known as flareless fittings.
