Parker 179VL-6-4 Male 45 Degree Compression Elbow

Product Description

The PARKER 179VL-6-4 is a male 45 degree compression tube elbow fitting manufactured from brass. It connects a compression tube end to a male NPT threaded port, making a 45 degree directional change in the line. The 1/4-18 thread size is a standard NPT connection used across HVAC, refrigeration, hydraulic, and pneumatic plumbing systems. The fitting uses Parker Vibra-Lok compression style, which provides a reliable tube-to-fitting seal without soldering or flaring. Rated to 400 psi maximum working pressure, it handles the pressure demands of common trade applications. This fitting is installed by licensed plumbers, HVAC technicians, and pipefitters working on fluid or gas distribution lines.

This fitting is suited for residential and light commercial applications where a compression tube must transition to a male NPT threaded port at a 45 degree angle. Typical use cases include refrigerant line routing, instrument tubing, and hydraulic or pneumatic control circuits where rigid tubing requires a directional change at a threaded component. The Vibra-Lok compression design allows for secure connections in vibration-prone environments, making it practical for equipment-mounted tubing runs.

Compatibility

Designed as an OEM-style compression tube fitting for systems using 1/4-18 male NPT threaded ports and compatible compression tube sizes in HVAC, refrigeration, hydraulic, and pneumatic plumbing applications.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or HVAC technician. Depressurize and isolate the line 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 end. Follow applicable codes including IFGC or IPC as relevant to the media being conveyed.
