The PARKER 682VL-5-4 is a brass compression tube connector designed to join a compression tube end to a male NPT threaded port in fluid and gas distribution systems. Featuring Vibra-Lok compression style and a 1/4-18 inch NPT thread, this connector holds a maximum working pressure of 500 psi. Constructed from brass, it offers reliable corrosion resistance and durability in a wide range of plumbing, refrigeration, and instrumentation applications. Licensed plumbers, HVAC technicians, and instrumentation mechanics are the primary installers of this fitting type.
This compression connector is suited for residential and light commercial installations where a tube line must terminate at a male NPT port. Common applications include refrigerant line connections, pneumatic control tubing, fuel gas distribution, and instrumentation piping. The Vibra-Lok compression design allows for secure, vibration-resistant connections without requiring solder or flare tooling, making it practical for field installations where torch work is impractical or restricted.
Designed as an OEM-style replacement or new-installation fitting for systems using standard 1/4-18 NPT threaded ports with compression tube connections in plumbing, HVAC, and instrumentation applications.
This fitting is installed by licensed plumbers or HVAC technicians working on pressurized fluid or gas systems. Shut off and depressurize the system fully before removing or installing any compression fitting. Ensure the tube end is cut cleanly and squarely and is free of burrs before seating it into the compression fitting. Follow all applicable IPC, IFGC, or NEC guidelines as relevant to the system being serviced.
