Parker VS279NTA-4-4 Brass Compression 45 Elbow 1/4 Mnpt

Product Description

The PARKER VS279NTA-4-4 is a brass compression-to-male-NPT 45-degree elbow fitting designed for use in fluid and pneumatic line assemblies. It connects a compression tube end to a male NPTF-threaded port at a 45-degree angle, allowing directional routing of tubing in tight or angled installations. With a maximum working pressure of 150 psi and an operating temperature range of -40 degrees F to 200 degrees F, this fitting suits hydraulic brake, fuel, and pneumatic applications where D.O.T. and SAE compliance is required. Weighing 0.08 pounds, it is a compact, single-piece brass fitting intended for installation by licensed plumbers, fleet mechanics, and HVAC or pneumatic system technicians.

This fitting is suited for mobile equipment, fleet vehicle brake and fuel line systems, and industrial pneumatic assemblies requiring a reliable 45-degree directional change. The compression-by-MNPT configuration makes it appropriate for connecting copper or nylon tubing to a fixed male-threaded port on valves, manifolds, or equipment housings. It meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards, making it a compliant choice for on-highway vehicle brake system tubing installations as well as general fluid line work.

Key Features

• Brass construction for corrosion resistance and reliable sealing in fluid and pneumatic service
• 45-degree elbow geometry allows directional routing without bending or stressing tubing
• Compression x MNPT end connections for tool-free tube attachment to threaded ports
• Rated to 150 psi maximum working pressure
• Wide temperature range: -40 degrees F to 200 degrees F
• Meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards

Compatibility

Designed as an OEM-style compression fitting for fluid and pneumatic line assemblies requiring a 1/4 inch NPTF male threaded port connection with a 45-degree tube exit.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with D.O.T. brake and fluid line regulations. Depressurize and isolate the system completely before removing or installing any fittings. Ensure the compression sleeve and nut are properly seated on the tubing before tightening to avoid leaks or tube pullout. Thread engagement should comply with applicable SAE and NPTF standards; do not overtighten, as brass threads can deform under excessive force.
