ConFlat Zero Length Reducer DN160CF (8.00" OD), DN63CF (4.50" OD), ID 2.5, 304SS

Zero-length reducer flanges are used to change sizes within the CF family while producing the smallest possible transition footprint (only 1 flange thickness). These transition flanges allow thermocouple gauges or up-to-air valves to be quickly added to your vacuum system with minimal system alterations and minimal impact on system conductance.
