Parker 372HB-6-6PP Male Branch Tee 3/8 in Barb Npt

Product Description

The PARKER 372HB-6-6PP is a male branch tee fitting designed for barbed tube connections in fluid handling and pneumatic systems. Molded from polypropylene, this black fitting accepts 3/8 inch barbed tubing on the branch and run ports and terminates with a 3/8 inch NPT male thread for inline connection to a threaded port or body. The male branch tee configuration allows a single threaded entry point to split or merge flow across two barbed tube lines, making it a standard component in low-pressure fluid distribution, HVAC condensate management, plumbing accessory circuits, and light industrial pneumatic assemblies. Installers in HVAC, plumbing, and general mechanical trades will encounter this fitting in situations requiring a compact, corrosion-resistant branch connection.

This fitting is suited for residential and light commercial applications where polypropylene chemical resistance and low weight are priorities. Common install scenarios include condensate drain branching on HVAC equipment, water treatment distribution manifolds, and pneumatic control tubing assemblies. The 3/8 inch barb sizing accommodates standard 3/8 inch ID flexible tubing, and the 3/8 inch NPT male thread connects directly to female NPT ports on pumps, valves, tanks, and equipment panels. It is sold individually with a minimum order quantity of 5 units.

Key Features

• Male branch tee configuration splits or merges flow between one NPT port and two barbed tube lines
• Polypropylene construction provides corrosion resistance and compatibility with a broad range of fluids
• 3/8 inch barb size fits standard 3/8 inch ID flexible tubing
• 3/8 inch NPT male thread for direct connection to female NPT ports
• Black color for UV and chemical resistance in exposed or harsh environments
• Lightweight at 0.01 pounds, minimizing load on tubing and connected equipment

Compatibility

Designed as an OEM-style replacement or new-installation barbed tube male branch tee for systems using 3/8 inch ID flexible tubing and 3/8 inch NPT female threaded ports in HVAC, plumbing, and light industrial fluid or pneumatic circuits.

Installation Notes

This fitting is typically installed by HVAC technicians, plumbers, or mechanical contractors working on low-pressure fluid or pneumatic systems. Shut off fluid supply and relieve system pressure before disassembly or installation. Secure barbed connections with appropriate clamps and hand-tighten the NPT male thread into the female port, then snug with a wrench — do not overtighten polypropylene threads. Verify compatibility of the fitting material with the fluid media and operating temperature range of the specific application before installation.
