A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications.

Connect stainless steel tubing on one end and plastic tubing on the other end.

Instead of a metal sleeve (ferrule), these fittings have a rubber sleeve that cushions tubing and absorbs vibration to maintain a tight seal, even when connected to large pumps.

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

Quickly connect low-pressure stainless steel lines with these couplings. Made of 316 stainless steel, they have excellent corrosion resistance.

Twist these fittings onto high-vacuum tubing to quickly make sealed, high-vacuum connections without the need for clamping, welding, or tools.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Also known as KF, QF, and NW fittings, these fittings are for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases.

Fittings are polished to a32 Ra and under finish on the interior.

Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth.

Choose these metal fittings when you need better durability than our plastic push-to-connect fittings.

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

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

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

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

Save time installing sleeves and nuts—these sets come oriented in the correct direction and order on a dispenser.

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.

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

Also known as JIS (Japanese Industrial Standard) fittings.

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

For use in high-vacuum systems, these fittings use a metal reinforced O-ring to create an airtight seal. Also known as KF, QF, and NW fittings, they’re used for high-vacuum applications such as vacuum coating and heat treating, leak testing, and analyzing gases.

The plating on these brass fittings creates a shiny finish and provides extra protection in corrosive environments. Fittings have the strength to handle high-pressure applications.

When you're unsure of the exact thread type you need, these fittings have universal threads that are compatible with the most common ones (NPT, NPTF, BSPP, BSPT).

Plated with nickel, these brass fittings resist rust better than steel and unfinished brass fittings. Select them when you need more strength in corrosive environments to handle higher pressures than our low-pressure fittings.
