Parker VS279AB-6-4 Brass Compression Male 45 Elbow

Product Description

The PARKER VS279AB-6-4 is a brass compression-to-male NPTF 45-degree elbow fitting designed for use in fluid and pneumatic line assemblies where a directional change is required at a threaded port connection. The fitting features a 1/4-18 NPTF thread on the male end and a compression-style tube connection on the opposite end, making it suitable for connecting tubing to equipment ports in a single leak-resistant assembly. It is rated to 400 psi maximum working pressure and handles a temperature range of -65 degrees F to 250 degrees F. Licensed tradespeople and fleet maintenance technicians install this fitting in hydraulic, pneumatic, and brake line applications.

The VS279AB-6-4 is commonly used in vehicular and industrial fluid systems where space constraints require a 45-degree change of direction from a threaded port. Its compliance with D.O.T. FMVSS571.106 and SAE J246 standards makes it appropriate for brake and fuel line installations on commercial and fleet vehicles. It is also used in stationary equipment, compressor lines, and instrumentation plumbing where NPTF threaded ports and compression tube connections are standard. The brass construction offers corrosion resistance in contact with common hydraulic fluids, air, and water-based media.

Key Features

• Compression x Male NPTF end connections for tubing-to-port assembly
• Brass construction provides corrosion resistance for hydraulic, pneumatic, and fluid service
• Rated to 400 psi maximum working pressure
• Compliant with D.O.T. FMVSS571.106 and SAE J246 standards
• Wide temperature range: -65 degrees F to 250 degrees F

Compatibility

Designed as an OEM-style compression fitting for fluid and pneumatic systems requiring a 1/4-18 NPTF male thread with a compression tube end, consistent with D.O.T. FMVSS571.106 and SAE J246 compliant installations.

Installation Notes

Installation should be performed by a qualified technician familiar with compression fittings and NPTF thread sealing practices. De-pressurize and drain the system completely before removing or installing any fittings. NPTF threads are designed to seal on the threads themselves; avoid over-tightening, which can crack brass fittings. Verify that tubing outer diameter matches the compression end specification before assembly.
