Whether the control valve actuator is newly manufactured or being serviced for field calibration, the connector acts as an interface between the control valve actuator and calibration instrumentation. The connectors use a handle actuated collet system for fast, repeatable connections so that no wrench tightening or thread sealant is needed. A patented pressure-assisted grip and seal method provides a leak-tight 5000psi connection.Fastest Inc.www.fastestinc.com800.444.2373
