Parker VS279AB-12-8 Brass Compression 45 Elbow 1/2-14

Product Description

The PARKER VS279AB-12-8 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 plumbing layouts. The fitting is rated to 400 psi maximum working pressure and handles temperatures from -65 degrees F to 250 degrees F. Constructed from brass, it offers reliable corrosion resistance in a wide range of fluid handling applications. Licensed plumbers, HVAC technicians, and industrial pipefitters commonly install this type of fitting.

This elbow fitting is suited for residential and light commercial plumbing, refrigeration tubing, pneumatic lines, and hydraulic systems where a 45-degree directional change is required at a threaded port. The 1/2-14 NPTF thread size is a standard connection found on valves, manifolds, and equipment ports across HVAC, plumbing, and fluid power applications. The compression end accommodates tubing with an inside diameter of 0.533 inches, making it compatible with common copper and brass tubing in that size range.

Key Features

• 45-degree elbow geometry for angled tube routing without bending tubing
• Brass construction provides corrosion resistance in water, air, and refrigerant-adjacent service
• Rated to 400 psi maximum working pressure
• Wide temperature range: -65 degrees F to 250 degrees F
• 1/2-14 NPTF male thread for a pressure-tight dry-seal connection
• Compression end sized for 0.533-inch inside diameter tubing

Compatibility

Designed as an OEM-style replacement or service fitting for compression tube systems using 1/2-14 NPTF male threaded ports in plumbing, HVAC, and fluid power installations.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician following applicable IPC or IFGC guidelines. Shut off and depressurize the system completely before removing or installing any compression fitting. Do not overtighten the compression nut; hand-tighten first, then advance with a wrench to seat the ferrule without deforming the tubing. NPTF threads are designed for dry-seal engagement and do not require tape or thread sealant, though shop practice and system requirements may vary.
