Connect quick-clamp fittings in high-vacuum applications.

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.

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

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

Originally used on satellites, rocket propulsion systems, and even Mars rovers, these fittings will handle your most challenging industrial environments. They're designed to withstand high vibration and high vacuum without generating particles that could disrupt your operation.

For high-vacuum systems with tube sizes too large for quick-clamp (KF) fittings, choose these bolt-together fittings.

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.
