Parker 151F-6-8 Brass Male Run Tee 3/8 in Flare X Mnptf

Product Description

The PARKER 151F-6-8 is a brass male run tee fitting designed for flared tube connections in refrigeration, HVAC, and fluid-handling systems. It accepts a 3/8-inch tube OD on the flared ends and steps to a 1/2-14 NPTF male thread on the branch outlet. The 45-degree flare geometry creates a leak-resistant metal-to-metal seal without additional sealant. At 0.24 pounds, it is a compact, single-piece brass fitting suited for inline branching in tubing runs where a threaded NPT port is required on the branch side. HVAC technicians, refrigeration mechanics, and plumbers install this fitting when splitting or tapping a flared tubing circuit while maintaining a threaded connection at the run outlet.

This fitting is used in residential and light commercial HVAC and refrigeration piping, as well as hydraulic and pneumatic fluid lines that use 45-degree flare connections. It is well suited for installations where a flared copper or aluminum tube run must be branched to a threaded male NPT port, such as when adding a gauge port, additional line, or service connection to an existing flared circuit. The NPTF thread standard provides a pressure-tight mechanical seal at the male branch connection.

Key Features

• 3/8-inch tube OD flare connections on the run ends for standard flared tubing
• 1/2-14 NPTF male thread on the branch outlet for pressure-tight threaded connections
• 45-degree flare angle provides a reliable metal-to-metal seal
• Brass construction offers corrosion resistance in refrigerant, air, and fluid service
• Flare x MNPTF end configuration supports inline branching without adapters
• Compact single-piece body at 0.24 pounds minimizes weight in the assembly

Compatibility

Designed as an OEM-style replacement or service fitting for HVAC, refrigeration, and fluid-handling systems that use 45-degree flared tube connections with 3/8-inch tube OD and 1/2-14 NPTF male threaded branch ports.

Installation Notes

Installation should be performed by a licensed HVAC technician, refrigeration mechanic, or plumber. Depressurize and evacuate the system before disconnecting or installing any flare fitting. Inspect the tube end for proper flare geometry before seating the fitting to ensure a leak-free metal-to-metal seal. NPTF threads are designed to seal on the threads themselves, but always verify joint integrity with a pressure test after installation per applicable service procedures.
