Product Overview
Factory-Sealed ANCORP QF40-CLMP-SS KF40 Stainless Steel Vacuum Clamp
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.
Product Condition
Factory-sealed in original OEM packaging. The clamp has never been opened, installed, or handled outside its packaging.
Product Overview
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.
