Parker 244IFHD-8 Inverted Union Tee 1/2 in Tube Od

Product Description

The PARKER 244IFHD-8 is a heavy-duty inverted union tee fitting designed for flared tube connections in demanding hydraulic and fluid system applications. It accepts a 1/2-inch tube OD and uses a 3/4-18 UNF thread standard, providing a secure, leak-resistant connection at three ports. The inverted flare design mechanically seats the tube against the fitting seat, eliminating the need for ferrules or solder. This fitting is suited for high-vibration or high-pressure environments where a standard union tee would not hold up. Plumbers, HVAC technicians, and hydraulic system installers rely on this style of fitting when a branch connection is required in a flared-tube line.

The 244IFHD-8 is used in residential and light commercial fluid systems wherever a three-way branch in a flared copper or steel tube run is required. Typical applications include refrigeration line sets, automotive brake lines, hydraulic equipment plumbing, and fuel system distribution. Its heavy-duty construction makes it a preferred choice over standard-duty inverted tees in applications subject to mechanical stress, vibration, or repeated pressure cycling. Install it where two supply or return lines must be joined to a common branch in a flared-tube circuit.

Key Features

• Inverted union tee configuration allows full disassembly at all three ports without disturbing the tube run
• 1/2-inch tube OD sizing fits standard half-inch flared copper and steel tubing
• 3/4-18 UNF thread provides fine-pitch engagement for vibration resistance
• Heavy-duty construction rated for higher mechanical loads than standard-duty equivalents
• No ferrule or solder required — flared seat provides the primary seal

Compatibility

Designed as an OEM-style replacement or service fitting for flared-tube hydraulic, refrigeration, and fluid distribution systems using 1/2-inch OD tubing with a 3/4-18 UNF inverted flare connection.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified hydraulic technician. Depressurize and drain the system completely before removing or installing any fitting. Ensure the tube end is properly flared to the correct angle and free of burrs before threading the nut; a damaged or under-flared seat will result in a leak. Hand-tighten the union nuts to seat the flares, then wrench-tighten to the fitting manufacturer's standard for the tube size and material — do not overtighten, as this can crack the flare.
