ANCORP CNC Stainless Steel KF Clamp
ANCORP’s CNC Stainless Steel KF Clamp is the preferred method for fastening QF (KF) flange connections due to offering the fastest and easiest fastening method for creating a reliable ISO vacuum seal. Our clamp sets the industry standard for QF (KF) flange connections by delivering unmatched reliability, durability, and ease of use. The clamp is manufactured from a solid 300 series stainless steel billet, offering superior corrosion resistance, structural integrity, and consistent performance in demanding vacuum environments. The CNC clamp is the go-to solution for high vacuum applications where secure, leak-free connections are critical.
Trusted in applications such as:
- Semiconductor manufacturing
- Thin film deposition
- Cryogenics
- High-vacuum systems
Its robust construction and precise fit ensure long-term performance through vibration, thermal cycling, and repeated use.
Features
- CNC-machined from solid 300 series stainless steel billet to provide exceptional corrosion resistance, long-term material stability, and compatibility with UHV cleaning procedures.
- Machined with tight dimensional control to eliminate casting porosity, misalignment, and vacuum leaks commonly found in cast or stamped clamps.
- Designed with a reinforced hinge mechanism, threaded fastener, and integrated lock washer to ensure even pressure distribution and superior vibration resistance.
- Studs are treated with anti-seize compound to prevent galling and allow for smooth, repeatable fastening over time.
- Reduces the risk of fastener loosening, making it ideal for cleanroom environments and applications requiring repeatable processes. Reliable torque characteristics help protect sensitive system components.
- Fully compatible with all ISO standard vacuum flanges and fittings.
- Eliminates the need for over-pressure rings on QF16, QF25, and QF40 sizes, simplifying installation and reducing parts.
- Integrated locking handle prevents accidental opening and ensures secure closure during operation.
