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.

High-Polish Metal Quick-Clamp Sanitary Tube Fittings
- Temperature Range: See Gaskets or O-Rings
The smooth finish inside these fittings makes it easy to remove product residue. Also known as aseptic and tri-clamp fittings, they connect with a gasket or O-ring, a clamp, and another quick-clamp fitting for a fast and easy way to access your line. The pressure rating of the fitting will vary depending on the clamp you choose, and the temperature rating will vary based on the gasket or O-ring material you choose.
Inch fittings connect to another same-sized fitting and squeeze the gasket in between for a tight seal.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.
3-A certified fittings comply with sanitary standards.
Note: To complete a connection, you’ll need two quick-clamp fittings, a clamp, and a gasket or O-ring (all sold separately).

Gaskets and O-Rings
The temperature rating of the fitting will vary depending on the gasket or O-ring material you choose. Buna-N gaskets are oil resistant. EPDM gaskets or O-rings resist water and steam and work well in humid environments. Silicone gaskets withstand high temperatures. Fluoroelastomer gaskets or O-rings stand up to fuel, oil, and acid condensates. PTFE gaskets or O-rings withstand harsh chemicals, with the exception of molten alkali metal and elemental fluorine.

Extra-Support High-Polish Metal Quick-Clamp Sanitary Tube Fittings
- For Use With: Dairy, Water
- Temperature Range: -30° to 200° F
- Tubing:
304 Stainless Steel: Use with welded 304/304L or 316/316L stainless steel that meets ASTM A269 or ASTM A270
316 Stainless Steel: Use with welded 304/304 L or 316/316L stainless steel - Specifications Met: See table
Also known as I-line fittings, these quick-clamp fittings permit easy access to your line. They have a smooth finish on the interior to prevent bacterial growth and help you remove product residue. The pressure rating of the fitting will depend on the clamp you choose.
304 stainless steel fittings have very good corrosion resistance. They’re 3-A certified to meet sanitary design standards. Note: To complete a connection, you’ll need a male and female straight adapter, a clamp, and a gasket (all sold separately).

Quick-Clamp High-Vacuum Fittings for Stainless Steel Tubing
- 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).
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).

Valves with Shut-Off
Valves (sold separately) 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.

Claw-Clamp High-Vacuum Fittings for Stainless Steel Tubing
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. To complete a connection, use a ring and four clamps (sold separately). Not for use in pressure applications.
Double-claw clamps attach to the grooves on the fittings.
Single-claw clamps have a clamp on one end and an exposed bolt on the other. Thread the bolt-end directly into the body of pumps, valves, or other high-vacuum components.
