Parker 259IFHD-10-8 Brass Inverted 45 Flare Elbow 5/8 in

Product Description

The PARKER 259IFHD-10-8 is a brass inverted 45-degree flare elbow fitting designed for use in fluid and refrigerant line assemblies where a direction change is required at a flared tube connection. The fitting accepts a 5/8-inch tube OD on the flare end and connects to a 1/2-14 NPTF male pipe thread on the other end. Rated to 650 psi maximum working pressure and 250 degrees F maximum working temperature, this fitting is suited for hydraulic, fuel, and refrigeration applications. It meets SAE J51 standards and carries a UL listing. Licensed plumbers, HVAC technicians, and hydraulic system technicians are the primary installers.

This fitting is used in residential and commercial systems where an inverted 45-degree flare connection transitions to a male NPTF pipe thread port. Typical applications include refrigeration line sets, fuel delivery systems, hydraulic circuits, and other fluid-handling assemblies requiring a reliable, leak-resistant angled connection. The brass construction offers corrosion resistance in a wide range of fluid service conditions. The overall installed length is 1.75 inches, making it suitable for space-constrained routing in equipment panels and mechanical rooms.

Compatibility

Designed as an OEM-style replacement or service fitting for fluid, fuel, and refrigeration line assemblies using 5/8-inch OD inverted 45-degree flare tube connections with a 1/2-14 NPTF male pipe thread port.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified hydraulic technician following applicable codes. Depressurize and isolate the system completely before removing or installing any fittings. Use appropriate flaring tools to ensure the tube end meets SAE J51 inverted flare geometry before assembly. Do not overtighten; apply thread sealant compatible with the service fluid on the NPTF threads only, keeping the flare seat clean and free of sealant.
