Parker 6MBT4N-B Compression Male Branch Tee 3/8 Inch Brass

Product Description

The PARKER 6MBT4N-B is a brass compression tube male branch tee designed for use in fluid and gas distribution systems where a branch connection is needed along a tube run. The fitting accepts 3/8 inch outside diameter tubing on both compression ends and terminates with a male NPT threaded port, allowing inline branching to a threaded component. Rated to 2300 psi maximum working pressure, this fitting is built for demanding service in hydraulic, pneumatic, refrigeration, and instrumentation applications. The all-brass construction provides corrosion resistance and reliable sealing under pressure. HVAC technicians, plumbers, and instrumentation specialists are the typical installers.

This fitting is suited for residential and commercial installations where a copper or compatible soft-metal tube line must branch to a threaded male connection. Common applications include refrigerant line sets, compressed air distribution, fuel gas systems, and instrumentation tubing. The compression-by-compression-by-MNPT configuration makes it easy to tap into an existing tube run without soldering or special tooling. It is sold individually and ships as a single-piece unit.

Key Features

• Brass construction for corrosion resistance and durability in fluid and gas service
• 2300 psi maximum working pressure rating for high-pressure applications
• 3/8 inch tube outside diameter on both compression ports
• Male NPT branch port for direct connection to threaded fittings or valves
• Compression connections require no soldering or brazing at the tube ends
• Compact branch tee geometry fits standard tube configurations in tight spaces

Compatibility

Designed as an OEM-style replacement or direct-use compression tube branch tee compatible with 3/8 inch OD tubing systems using male NPT threaded branch connections. Cross-reference: Swagelok part number B-600-3-4TTM.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or instrumentation mechanics. Depressurize and isolate the tube line completely before disassembly or fitting installation. Compression fittings must be tightened to proper engagement using two wrenches to avoid tube or ferrule damage — do not overtighten. Follow applicable codes including IFGC or IPC for gas and fluid piping systems, and verify the fitting material and pressure rating are appropriate for the specific fluid and operating conditions.
