Parker 244IFHD-6 Brass Inverted Union Tee 3/8 in

Product Description

The PARKER 244IFHD-6 is a brass inverted union tee fitting designed for flared tube connections in refrigeration, HVAC, and fluid-handling systems. It accepts 3/8-inch tube OD with a 5/8-18 UNF thread on all three ports and provides a leak-resistant flare-to-flare-to-flare junction. Rated to 1000 psi maximum working pressure and 250 degrees F, this fitting handles the demands of high-pressure refrigerant and hydraulic lines. HVAC technicians and refrigeration mechanics are the primary installers. The all-brass construction resists corrosion and holds up in both indoor and outdoor service environments.

This fitting is suited for residential and light commercial HVAC systems, refrigeration circuits, and hydraulic tubing assemblies where a branch connection is needed on a flared-tube run. It is appropriate wherever an inverted flare union tee is specified in 3/8-inch OD tubing. The compact overall length of 1.48 inches allows installation in tight equipment compartments. SAE J51 compliance and UL listing make it acceptable for refrigerant service work under standard industry codes.

Compatibility

Designed as an OEM-style replacement or service fitting for HVAC, refrigeration, and hydraulic tubing systems using 3/8-inch OD inverted flare tube connections with 5/8-18 UNF threads.

Installation Notes

Installation is performed by licensed HVAC technicians or refrigeration mechanics. Recover and evacuate refrigerant from the system before opening any flared connections, following EPA Section 608 requirements. Inspect flare seats on all mating tube ends for nicks or deformation before assembly. Do not overtighten flare nuts, as brass fittings are susceptible to seat damage from excessive torque.
