KF50 Aluminium Alloy KF Vacuum Clamp Double Pin Three Jig With Bracket O-ring Why you need this clamp Secure, repeatable vacuum seals: Designed for the KF50 standard, this clamp provides reliable sealing between KF/NW50 flanges when used with the supplied O-ring. It reduces leaks and the need for repeated adjustments. Faster assembly and maintenance: The double pin three jig design centers and clamps evenly, making installation and removal quicker and reducing the risk of tilted flanges or damaged seals. Lightweight, corrosion-resistant construction: Aluminium alloy body keeps the clamp light for frequent handling while offering good resistance to corrosion in typical vacuum environments. Key attributes Model/Size: KF50 (compatible with standard KF/NW50 vacuum flanges) Material: Aluminium alloy body for reduced weight and ease of handling Design: Double pin three jig configuration for even pressure distribution around the flange Included: Bracket for mounting support and an O-ring for immediate use and proper sealing Functionality: Provides a robust clamping force to hold KF50 flange joints securely and align flanges during assembly What makes it unique Double pin three jig mechanism delivers uniform compression around the flange, lowering the chance of leaks and O-ring deformation compared with single-pin clamps. Bracket included for added stability during installation or when mounting the clamp to fixtures. Supplied O-ring matched for KF50 use so the clamp is ready to install on delivery. Applications and use cases Research labs and test benches: Quick, repeatable connections for vacuum chambers, instrumentation, and modular setups where frequent reconfiguration occurs. Pump and foreline connections: Securely clamp KF50 flanges between pumps, valves, and components in vacuum plumbing and service lines. Prototyping and light industrial vacuum assemblies: Convenient for small-scale vacuum systems, maintenance tasks, and equipment integration where ease of use and speed matter. Practical notes Use the included O-ring rated for KF50 flanges and inspect it for damage before installation to ensure proper sealing. Tighten evenly and avoid over-torquing; the double pin three jig design helps maintain alignment and reduces localized stress on the flange and O-ring. Aluminium alloy offers weight and handling benefits; inspect for wear on the clamp or O-ring if signs of fatigue or deformation appear.
