Parker VS279AB-10-6 Brass 45 Elbow 3/8-18 Nptf

Product Description

The PARKER VS279AB-10-6 is a brass compression-to-male NPTF 45-degree elbow fitting designed for use in fluid and pneumatic tubing systems. It connects a compression tube end to a male NPTF threaded port at a 45-degree angle, allowing directional routing in tight or angled installations. The fitting is rated to 400 psi maximum working pressure and handles temperatures from -65 degrees F to 250 degrees F. With a 0.408-inch inside diameter, it suits 3/8-18 NPTF thread applications. Installers in plumbing, HVAC, and hydraulic system work rely on this type of fitting for reliable, leak-resistant tube terminations where a straight fitting will not clear surrounding hardware.

This fitting is suited for residential and light commercial fluid system applications including hydraulic lines, pneumatic control circuits, and general-purpose tubing runs. The 45-degree elbow geometry is useful where tubing must change direction without a sharp bend, reducing stress on the tube wall. The NPTF male thread provides a dry-seal connection, minimizing the need for additional thread sealant when properly torqued. It is commonly installed in equipment panels, manifold assemblies, and inline service points where space constraints prevent the use of a straight compression fitting.

Key Features

• 45-degree elbow geometry allows angled tube routing in space-constrained installations
• Brass construction provides corrosion resistance for water, air, and compatible fluid service
• Compression x Male NPTF end connections for secure, leak-resistant assembly
• Rated to 400 psi maximum working pressure
• Wide temperature range: -65 degrees F to 250 degrees F
• 3/8-18 NPTF thread standard for dry-seal performance

Compatibility

Designed as an OEM-style compression fitting for tubing systems requiring a 3/8-18 NPTF male thread connection with a compression tube inlet at a 45-degree offset angle.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians. Depressurize and isolate the system completely before removing or installing any compression fitting. Ensure the tube end is cut square and deburred before seating it into the compression sleeve to achieve a proper seal. Follow applicable codes such as the IPC or system manufacturer guidelines for thread engagement and tube insertion depth.
