Edwards NW10/16 Clamping Ring Stainless Steel for Vacuum Pump Lot of 3 Clamps

Edwards Clamping Ring (C10512401) – NW10/16 Stainless Steel, Lot of 3

The Edwards C10512401 is a high-strength vacuum clamping ring designed to secure NW10 and NW16 (KF10/KF16) flange connections. Unlike standard aluminum clamps, this premium model is manufactured from stainless steel, providing exceptional mechanical durability and resistance to corrosive environments. This lot of three clamps is engineered to provide the consistent, high-compression sealing force required for high-vacuum systems, turbomolecular pump backing lines, and analytical laboratory instrumentation.

Technical Performance & Design

• Heavy-Duty Stainless Steel Construction: Fabricated from 304-grade stainless steel, offering superior tensile strength and resistance to chemical attack, pitting, and oxidation compared to aluminum alternatives.
• 360-Degree Radial Compression: The inner wedge profile is precision-machined to distribute uniform sealing pressure across the entire circumference of the centering ring and O-ring assembly.
• Ergonomic Wing Nut Bolt: Features an integrated high-torque wing nut and swing bolt, allowing operators to achieve a secure, leak-tight seal manually without the need for specialized tools.
• ISO-KF Standard Compliance: Engineered to meet ISO 2861/1 dimensions, ensuring a flawless, universal fit with all standard NW10 and NW16 flanges across different hardware brands.

Product Specifications

Key Benefits & Applications

• Corrosive Foreline Environments: Perfect for vacuum pump exhaust and backing lines where exposure to corrosive gases or acidic vapors would cause aluminum clamps to degrade.
• Analytical Instrumentation: Provides the ultra-secure, low-outgassing connection necessary for mass spectrometers, electron microscopes, and leak detectors.
• Tool-Free "KF" Interconnectivity: The KF (Kleinflansch) shorthand geometry allows for rapid assembly and teardown during routine pump maintenance or manifold reconfigurations.
• High-Vibration Dampening: The rigid stainless steel frame maintains its clamping force even when subjected to the continuous mechanical vibrations of rotary vane or dry scroll pumps.
