Parker 179VL-4-2 Compression Male 45 Elbow 1/8-27 Brass

Product Description

The PARKER 179VL-4-2 is a male 45-degree compression tube elbow fitting manufactured from brass and designed to transition between a compression tube connection and a male NPT threaded port. It uses Parker's Vibra-Lok compression style, which provides a secure, vibration-resistant seal without requiring flare preparation or soldering. Rated to 600 psi maximum working pressure, this fitting is suited for hydraulic, pneumatic, and fluid-line applications where a reliable angled connection is needed at a 1/8-27 male NPT port. Licensed plumbers, HVAC technicians, and fluid-systems technicians install this fitting in control and instrumentation lines, refrigeration circuits, and compressed-air systems.

This fitting is commonly used in residential and commercial mechanical systems where a compression tube must be routed at a 45-degree angle to a male NPT port. Typical applications include instrument tubing connections, control-line assemblies, and refrigerant or compressed-air distribution where a straight run is not practical. The 1/8-27 thread size is a standard NPT size found on gauges, solenoid valve ports, manifold blocks, and similar small-port components. The operating temperature range of -30 degrees F to 135 degrees C (-22 degrees F to 275 degrees F) makes it appropriate for a wide range of HVAC, refrigeration, and fluid-power service conditions.

Key Features

• Vibra-Lok compression style provides a vibration-resistant, tool-assisted tube seal without soldering or flaring
• Brass construction offers corrosion resistance suitable for air, water, refrigerant, and light hydraulic fluid service
• 600 psi maximum working pressure rating
• 45-degree elbow geometry allows directional routing in tight installations
• Compression x MNPT end connections for direct interface with standard NPT-ported components
• Meets ISO 6149 and SAE J1926 standards

Compatibility

Designed as an OEM-style replacement or new-installation compression fitting for systems with 1/8-27 male NPT ports requiring a 45-degree compression tube transition.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or fluid-systems mechanics following applicable codes. Shut off and depressurize the system completely before removing or installing any compression fitting. Ensure the tubing end is cut squarely and deburred before inserting into the compression sleeve. Do not overtighten; follow standard hand-tight-plus-turns practice for compression fittings and verify for leaks before returning the system to service.
