Edwards Swing Clamp NW 20/25 Set of 3 Clamps

Edwards Swing Clamp (C10514304) – NW 20/25 Aluminum, Set of 3

The Edwards C10514304 is a high-performance vacuum hardware component designed to provide a secure, uniform seal between NW 20 or NW 25 (KF20/KF25) flanges. These swing clamps are engineered for rapid assembly and disassembly of vacuum lines, utilizing a specialized "swing" mechanism that allows for one-handed operation in tight spaces. This set of three clamps is essential for maintaining the integrity of high-vacuum systems in analytical laboratories, semiconductor processing, and research facilities.

Technical Performance & Design

• Quick-Release Swing Mechanism: Features a hinged swing-bolt design that enables fast attachment and removal without the need for tools, significantly reducing downtime during system maintenance.
• Optimized Pressure Distribution: The inner profile of the clamp is precision-machined to apply 360-degree radial compression onto the centering ring and O-ring for a leak-tight seal.
• High-Strength Aluminum Construction: Manufactured from die-cast aluminum to provide a lightweight yet rigid structure that resists deformation under vacuum pressures down to $10^{-8}$ mbar.
• Ergonomic Wing Nut: Equipped with a large, high-torque wing nut that allows operators to achieve the necessary clamping force manually, ensuring repeatable sealing performance.

Product Specifications

• Part Number: C10514304
• Flange Compatibility: NW 20 / NW 25 (KF 20 / KF 25)
• Material: Die-cast Aluminum (Body) / Stainless Steel (Pin and Bolt)
• Quantity: Set of 3 Clamps
• Vacuum Rating: High Vacuum ($10^{-8}$ mbar / $7.5 \times 10^{-9}$ torr)
• Temperature Rating: Up to 150°C (Dependent on O-ring material)

Key Benefits & Applications

• Rapid System Reconfiguration: Ideal for R&D environments where vacuum manifolds, traps, and sensors must be frequently moved or swapped.
• Foreline & Roughing Isolation: Frequently used to connect scroll, rotary vane, or turbomolecular pumps to the main vacuum chamber or exhaust lines.
• Tool-Free Maintenance: The NW-standard shorthand (KF) interface ensures compatibility across various brands, allowing for quick "plug-and-play" seal replacements.
• Space-Efficient Sealing: The swing-away bolt requires minimal clearance compared to bulkier chain clamps, making it perfect for high-density instrument cabinets.
