How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

For Use With:
Fittings with Gasket End: Air, Argon, Helium, Nitrogen
All Other Fittings: Air
Temperature Range: 0° to 300° F
Tubing: Use with 304/304L or 316/316L stainless steel
Specifications Met: ISO 2861

Instead of a gasket, these fittings have a special ring that is designed for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases. Also known as KF, QF, and NW fittings, they are the most common type of connection in high-vacuum systems. Connect with a clamp and another quick-clamp fitting for fast, easy access to your line. To use fittings in pressure applications, use a pressure-rated ring (sold separately).

Aluminum fittings have good corrosion resistance and are lighter than stainless steel fittings. 304 stainless steel fittings have very good corrosion resistance.

Note: To complete a connection, you’ll need two quick-clamp fittings, a ring, and a clamp (all sold separately).

Straight Adapters, Tube × Yor-Lok Tube

Fittings with Yor-Lok end connect plain-end stainless steel tubing using a nut with two sleeves that bite into the tubing to create a strong seal. Yor-Lok connections are manufactured to tight tolerances—use them for high-pressure applications such as supplying gas or liquid to a high-vacuum chamber. Also known as instrumentation fittings.

Straight Adapters, Tube × Male Gasket Tube

Fittings with gasket end connect with a stainless steel gasket (sold separately) instead of a rubber one, generating fewer particles to create a stronger high-vacuum seal. Their interior is ultra-smooth to attract fewer contaminants. These adapters are commonly used to add gases such as helium, argon, or nitrogen into high-vacuum systems. Also known as VCR fittings.

Straight Adapters, Tube × Flanged Tube

Fittings with flanged end connect to pumps, valves or gauges that have flanged connections. Also known as conflat, CF, or UHV fittings, they have a higher vacuum rating than quick-clamp fittings, so these adapters allow you to connect between different levels of vacuum within a system. A copper gasket (sold separately) creates a tight seal between the two flanges.

Straight Adapters, Tube × Claw-Clamp Tube

Fittings with claw-clamp end are often used to connect high-vacuum components with large-diameter connections, such as coating or heat-treating equipment, to components with smaller connections such as gauges, filters, or pumps. Also known as ISO-K fittings, they connect with four claw clamps and a ring (sold separately).

Valves with Shut-Off

Valves are also known as vacuum isolation valves. They connect to a vacuum system so you can install gauges, release gases, and remove air. They operate manually and have a compact body that fits easily into tight spaces.

Quick-Connect High-Vacuum Fittings for Stainless Steel Tubing

Twist these fittings onto high-vacuum tubing to quickly make sealed, high-vacuum connections without the need for clamping, welding, or tools. To connect, insert your tubing into the fitting and twist the collar on the end of the fitting; an O-ring on the inside of the fitting compresses to form the seal. Also known as quick-disconnects, they're as easy to twist off as they are to twist on. Not for use in pressure applications.

Adapters have a quick-connect fitting on one side and a quick-clamp fitting on the other. Use them to attach and remove components for one-off uses or to adapt your quick-clamp system to connect to glass tubing. Quick-clamp fittings are also known as KF, QF, and NW fittings; they require a clamp and ring (sold separately) to complete the connection.
