Quick-Clamp High-Vacuum Fittings for Stainless Steel Tubing
- For Use With:
Fittings with Gasket End: Air, Argon, Helium, Nitrogen
All Other Fittings: Air - Specifications Met: ISO 2861
Instead of a gasket, these fittings have a metal-reinforced O-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). Made of 304 stainless steel, these 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).

- Temperature Range: 0° to 300° F
- Tubing: Use with 304/304L or 316/316L stainless steel
Fittings with butt-weld end weld to tubing for a permanent connection. Fittings with butt-weld end are also known as ferrules.

Clamps for Claw-Clamp High-Vacuum Fittings for Stainless Steel Tubing
Connect claw-clamp high-vacuum fittings for an airtight seal. For a complete connection, you'll need four clamps and a ring (sold separately).
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.

Quick-Clamp High-Vacuum Fittings for Aluminum Tubing
- For Use With: Air
- Specifications Met: ISO 2861
For use in high-vacuum systems, these fittings use a metal reinforced O-ring to create an airtight seal. To form a complete connection, pair two adapters with a clamp and a ring (all sold separately). Made of aluminum, these fittings are lightweight and resist corrosion. This and the airtight seal make them a good choice for vacuum coating, heat treating, or leak testing. Also known as KF, QF, and NW fittings.
