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.

The thick walls of these fittings can withstand more than twice the pressure of standard compression fittings.

Create airtight seals in high-vacuum systems by placing these rings between two claw-clamp (ISO-K) or bolt-together (ISO-F) fittings.

An alternative to bolt-together fittings, these handle larger tube OD sizes and have higher vacuum ratings than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.

Create access points in ultra-high-vacuum lines or chambers by bolting two same-size flanges together with a copper gasket between them. The flanges’ sharp edges dig into the copper gasket and form an extremely tight seal, which means they handle higher vacuum pressures than other high-vacuum fittings with rubber gaskets.

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

Connect claw-clamp high-vacuum fittings for an airtight seal.

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

Use at pressures up to 4,300 psi.

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

Connect quick-clamp sanitary tube fittings—also known as aseptic fittings—for a fast and easy way to access your line.

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.

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.

Create a strong seal on copper tubing when you couple these nuts with compression sleeves and fittings.

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 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.

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.

Also known as JIS (Japanese Industrial Standard) fittings.

Use these fittings in an air vacuum system to avoid the hassle of brazing and welding. Insert two fittings into a clamp and tighten to form a secure seal in steel tubing.

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

With the best corrosion resistance of any metal fitting we offer, these Hastelloy fittings will stand up to aggressive chemicals and are resistant to pitting and stress cracking. Also known as instrumentation fittings, they include a nut with two sleeves.

These brass fittings have the strength to handle high-pressure applications.

Not only do these brass fittings have the strength to handle high-pressure applications, the male threads have a sealant applied for extra protection against leaks.

Typically used with high-pressure brass and bronze threaded pipe fittings.

When space in your pipe line is limited, choose these miniature fittings that are one inch or less in length.

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.

Typically used with low-pressure brass and bronze threaded pipe fittings.

Less than an inch in length, these miniature fittings work well in low-pressure pipe lines that are tight on space.

Also known as Pressure Class 150 flanges, these brass flanges are designed for low-pressure applications.

Bolt these flanges to another same-size flange with a gasket to create an access point within a pipe line. They are also known as Silbraze flanges.

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

Also known as Pressure Class 1500 steel flanges, these have the strength to handle high pressures.
