Holyoke Fittings 44R-446 Male Flare Tee 1/4x1/4x3/8 Od

Product Description

The HOLYOKE FITTINGS 44R-446 is a male flare tee fitting used to split or combine refrigerant or fluid lines in HVAC, refrigeration, and plumbing applications. It features three connection ports sized at 1/4 inches OD, 1/4 inches OD, and 3/8 inches OD, allowing two same-size lines to join or branch off a larger-diameter line. The male flare ends create a metal-to-metal seal when torqued against a mating female flare seat, eliminating the need for thread sealants on the flare connections. This type of fitting is typically installed by licensed HVAC technicians and refrigeration mechanics working on split systems, condensing units, and process cooling lines.

The 44R-446 is suited for residential and light commercial HVAC and refrigeration systems where copper tubing requires a tee branch point. The combination of 1/4 inches and 3/8 inches OD ports makes it practical in situations where a main line and a smaller branch line must connect at a single junction. It is appropriate for use in new installations and service work where a reliable, leak-free flare joint is required at a branching connection.

Key Features

• Three-port male flare tee configuration: 1/4 inches OD x 1/4 inches OD x 3/8 inches OD
• Metal-to-metal flare seal eliminates need for thread sealant at flare connections
• Designed for copper tubing used in refrigerant and fluid line applications
• Compact tee body suitable for tight installation spaces in HVAC equipment cabinets

Compatibility

Designed as an OEM-style replacement or service fitting for HVAC and refrigeration systems using standard SAE male flare copper tubing connections at 1/4 inches OD and 3/8 inches OD tube sizes.

Installation Notes

Installation of flare fittings should be performed by a licensed HVAC technician or refrigeration mechanic. Recover and isolate any refrigerant from the system before cutting into existing lines, following EPA Section 608 requirements. Use a calibrated flaring tool to produce clean, properly formed flare seats on the copper tubing before making up the connections. Inspect all flare seats for cracks or deformation before tightening, and leak-test all connections after installation.
