4 Pcs KF50 Aluminum Vacuum Clamp + KF Stainless steel Centering Ring with O-ring

EastVAC KF25 Clamp: Reliable Sealing For Your Vacuum Systems A secure, leak-proof seal is critical for any vacuum setup—and EastVAC’s KF25 clamp delivers exactly that with premium materials and thoughtful engineering. Designed specifically for NW/KF-25 vacuum components, this clamp solves common issues like poor alignment, weak sealing and difficult installation that plague generic clamps. Crafted from high-grade aluminum, the clamp boasts exceptional corrosion resistance and structural strength, so it won’t bend or degrade even in frequent use. Each set includes a precision-machined KF25 centering ring and FKM O-ring: the centering ring ensures perfect alignment between 40mm ferrule OD flanges, while the FKM O-ring stands up to temperatures up to 200°C and resists aggressive chemicals, maintaining a tight seal in harsh conditions. The ergonomic wing nut and hinged design make installation a breeze—no tools required. Simply position the clamp over the flanges, tighten the wing nut by hand, and the hinge structure distributes pressure evenly for a consistent seal. Whether you’re building a degassing chamber, maintaining a vacuum oven, or working on vent lines, this versatile clamp fits seamlessly into your setup. It’s built to handle high-vacuum environments, providing reliable performance for both industrial and hobbyist applications. Choose EastVAC for vacuum clamps that combine durability, convenience and precision.
