Parker 259IFHD-3-2 Brass Inverted 45 Flare Elbow 3/16 in

Product Description

The PARKER 259IFHD-3-2 is a brass inverted 45-degree flare elbow fitting designed for tubing connections in hydraulic, pneumatic, and fluid-transfer systems. It accepts a 3/16-inch tube OD on the flare end and connects to a 1/8-27 NPTF male port on the threaded end. Rated to 1900 psi maximum working pressure and 250 degrees F, this fitting is built for demanding service conditions. The brass construction offers corrosion resistance in fuel, oil, and refrigerant lines. At 0.88 inches overall length, it fits tight routing situations where a standard 90-degree elbow cannot be used. Meets SAE J51 and is UL Listed.

This fitting is used in residential and light commercial applications involving brake lines, fuel lines, HVAC refrigerant circuits, hydraulic controls, and compressed-air tubing runs. The inverted 45-degree flare design is common in automotive and OEM fluid-system plumbing, as well as field service repairs requiring a direction change at a male NPTF port. Plumbers, HVAC technicians, and hydraulic system technicians install this type of fitting when routing small-diameter tubing through confined equipment enclosures or panel assemblies.

Key Features

• Inverted 45-degree flare x MNPTF ends for directional tube routing at a male port
• 1900 psi maximum working pressure for high-pressure fluid and pneumatic service
• Rated to 250 degrees F (121 degrees C) maximum working temperature
• Brass construction provides corrosion resistance in fuel, oil, and refrigerant environments
• Meets SAE J51 standard and is UL Listed
• Compact 0.88-inch overall length suits tight plumbing runs

Compatibility

Designed as an OEM-style replacement or service fitting for small-diameter tubing systems using 3/16-inch OD tubing with a 1/8-27 NPTF male port connection in hydraulic, pneumatic, or fluid-transfer applications.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified hydraulic systems technician familiar with flared tubing connections. Shut off and depressurize the system fully before removing or installing any fittings. Use a calibrated flaring tool to ensure the tube end meets SAE J51 inverted flare geometry before assembly. Do not overtighten; consult applicable industry torque guidelines for brass fittings of this thread size and apply thread sealant only if required by the system design and compatible with the fluid being conveyed.
