The ANCORP QF40-CLMP-SS is a CNC-machined KF40 vacuum clamp made from 304 stainless steel, designed for secure, repeatable sealing of quick-flange (QF/KF) fittings. This precision component ensures leak-tight connections in laboratory and industrial vacuum systems using standard NW/KF40 flanges.
ANCORP has supplied high-quality vacuum hardware to laboratories and manufacturing facilities for decades, recognized for consistency, material integrity, and precise machining. The QF40-CLMP-SS exemplifies that standard—robustly made for reliable service in clean environments and high-vacuum setups.
Factory-sealed in original OEM packaging. The clamp has never been opened, installed, or handled outside its packaging.
This KF40 clamp is part of the quick-flange (QF) connection system commonly used in vacuum lines and chambers. Machined from 304 stainless steel, it provides corrosion resistance, mechanical strength, and dimensional stability. When paired with a centering ring and O-ring, it delivers consistent sealing performance across a wide vacuum range—from roughing lines to high-vacuum applications.
It is factory-sealed and unused, in original OEM packaging.
Machined from 304 stainless steel, providing corrosion resistance and long-term mechanical stability.
It fits standard KF40 (NW40) quick-flange connections used in vacuum systems worldwide.
No. This listing is for the KF40 clamp only.
When installed correctly, KF clamps can maintain high-vacuum integrity down to approximately 10⁻⁷ Torr.
Precision-machined from stainless steel and sealed since manufacture, this ANCORP clamp is ready to join the next assembly that demands a perfect vacuum connection.
