Parker VS279NTA-6-4 Brass Compression 45 Elbow 1/4 Mnpt

Product Description

The PARKER VS279NTA-6-4 is a brass male 45-degree elbow fitting designed for compression-to-MNPT connections in fluid and pneumatic line assemblies. It accepts a compression tube connection on one end and a 1/4-inch male NPTF threaded connection on the other, allowing a controlled directional change in tubing runs. Rated to 150 psi maximum working pressure, this fitting handles temperatures from -40 degrees F to 200 degrees F. The brass construction provides corrosion resistance suited to hydraulic brake, fuel, and air line applications. It meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards, making it appropriate for regulated mobile and stationary system work.

This fitting is commonly used in mobile equipment, automotive brake and fuel line systems, and light industrial pneumatic or hydraulic assemblies where a 45-degree direction change is needed at a compression tube-to-pipe thread transition. The NPTF thread standard ensures a pressure-tight mechanical seal without relying solely on thread sealant. Typical installers include fleet mechanics, hydraulic system technicians, and plumbing or HVAC professionals routing small-diameter tubing to threaded ports.

Key Features

• Brass construction resists corrosion in fuel, air, and hydraulic fluid service
• Rated to 150 psi maximum working pressure
• Operating temperature range of -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-to-MNPT fitting for 1/4-inch tube connections in mobile, automotive, and light industrial fluid or pneumatic line systems meeting D.O.T. and SAE specifications.

Installation Notes

Installation should be performed by a qualified mechanic or fluid systems technician. Depressurize and drain the line completely before removing or installing any compression fitting. Hand-tighten the compression nut first, then use a wrench to bring it to a snug seat — do not overtighten, as brass fittings can crack under excessive torque. Verify thread compatibility and apply thread sealant per system requirements before final assembly.
