Parker 6MBT6N-B Compression Male Branch Tee 3/8 in

Product Description

The PARKER 6MBT6N-B is a brass compression tube male branch tee designed for use in fluid and gas distribution systems requiring a reliable three-way connection. The fitting provides two compression end connections and one male NPT port, allowing a branch takeoff from a compression tube run to a threaded port. Rated to 2300 psi maximum working pressure and manufactured from brass to ASTM-B-453 and ASTM-B16 standards, this tee is built for demanding service in HVAC, refrigeration, instrumentation, and plumbing applications. Licensed HVAC technicians, plumbers, and instrumentation specialists are the primary installers.

This fitting is suited for residential and light commercial systems where a branch connection is needed off an existing compression tube line with a transition to male NPT pipe thread. Common applications include instrument tubing manifolds, refrigerant line accessories, hydraulic control lines, and potable or process fluid distribution panels. The 3/8-inch thread size and tee configuration make it a practical choice for routing lines to pressure gauges, valves, or secondary supply points.

Key Features

• Two compression ends plus one 3/8-inch MNPT port for branch takeoff without additional adapters
• 2300 psi maximum working pressure for high-pressure fluid and gas service
• Brass construction per ASTM-B-453 and ASTM-B16 for corrosion resistance and machinability
• Overall length of 2.62 inches in a compact tee profile
• Cross-referenced to Swagelok part number B-600-3-6TTM for direct replacement sourcing

Compatibility

Cross-referenced to Swagelok part number B-600-3-6TTM. Designed as an OEM-style replacement fitting for compression tube systems using 3/8-inch male NPT branch connections in HVAC, refrigeration, and instrumentation piping.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or instrumentation specialist following applicable codes such as the IPC or IFGC. Depressurize and isolate the line completely before disassembling any existing fittings. Compression fittings should be tightened to finger-tight and then advanced with a wrench per standard compression fitting procedure — do not overtighten, as brass ferrules can deform and leak. Verify system pressure rating is within the 2300 psi working pressure limit of this fitting before returning the system to service.
