Stainless steel CF100 to KF25 vacuum pipe fitting (SUS 304) connector coupler designed to join a CF100 (ConFlat) flange to a KF25 (NW/KF) flange quickly and securely. Engineered for durability and compatibility with standard vacuum components. Key benefits Adapts different flange standards: allows direct connection between CF100 and KF25 hardware without custom machining. Durable, corrosionresistant construction: made from SUS 304 stainless steel for long service life and easy cleaning. Simple, reliable installation: provides a straightforward way to integrate vacuum pumps, gauges, and chambers with mismatched ports. Cost and time saver: avoids downtime and procurement delays by enabling onsite retrofits and system reconfigurations. Product highlights Functionality: Connector coupler for transitioning between CF100 flange and KF25 flange interfaces. Compatibility: Fits standard CF100 (ConFlat) and KF25 vacuum components conforming to their respective flange specifications. Material: SUS 304 stainless steel for strength, corrosion resistance, and chemical compatibility common in vacuum environments. Performance: Delivers a stable, leaktight connection when used with the appropriate CF100 copper gasket and KF25 Oring/clamp (use of proper gaskets, clamps, and correct torque is required for reliable sealing). Typical applications Laboratory vacuum systems: connect existing CF100 vacuum chambers to KF25 pumps, valves, or instrumentation during experiments or reconfigurations. Maintenance and retrofitting: retrofit older CF100 equipment with modern KF25 peripherals without replacing large assemblies. Research and prototyping: quickly assemble test benches and prototype vacuum setups where mixed flange types are present. Installation and usage notes This coupler provides mechanical adaptation only. Use the correct sealing elements for each flange type (CF100 copper gasket on the CF side; KF25 Oring and clamp on the KF side). Inspect sealing surfaces and gaskets or Orings as needed to maintain vacuum integrity. Tighten and assemble using standard practices for CF and KF flanges to avoid damage to flanges or seals. Materials and care SUS 304 stainless steel: clean with compatible solvents and avoid abrasive tools that can nick flange faces. Store in a clean, dry environment to preserve sealing surfaces. This CF100 to KF25 stainless steel connector coupler is a practical, durable solution for adapting mixed vacuum flange systems while maintaining compatibility with industrystandard gaskets and clamps.
