Parker BD-KP4424 Compression Tube Run Tee 3/8 in Ss

Product Description

The PARKER BD-KP4424 is a stainless steel compression tube run tee designed for inline branch connections in instrumentation and fluid system plumbing. The fitting joins a compression tube run to a male NPT branch port, allowing a technician to tap into an existing tube line without cutting the run. It accepts 3/8 inch outside diameter tubing on the compression ends and threads onto a female NPT port on the branch side. Stainless steel construction provides corrosion resistance in demanding service environments. This type of fitting is standard hardware for HVAC, process, and instrumentation installations where tube runs require a branch connection at a threaded port.

The BD-KP4424 is suited for residential and light commercial HVAC systems, refrigeration circuits, pneumatic control lines, and general instrumentation plumbing where a 3/8 inch OD tube run must branch to an NPT-threaded component such as a valve, gauge, or instrument port. It is installed by licensed HVAC technicians, plumbers, and instrumentation mechanics in applications requiring a reliable, leak-free compression connection without welding or soldering.

Key Features

• Run tee configuration keeps the main tube line continuous while adding a branch port
• 3/8 inch outside diameter compression connections on the run ends
• Male NPT branch end threads directly into a female NPT port
• Stainless steel body resists corrosion in wet, chemical, and high-humidity environments
• No soldering or brazing required — compression ends are tool-tightened

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with 3/8 inch OD tubing systems using compression-style connections and male NPT branch porting in HVAC, refrigeration, and instrumentation plumbing applications.

Installation Notes

Installation is performed by a qualified HVAC technician, plumber, or instrumentation mechanic. Depressurize and isolate the tube circuit fully before disassembling any compression fitting. Ensure tube ends are cleanly cut, deburred, and square before seating into the compression ferrule. Refer to applicable codes such as the IFGC or ASME B31.3 for allowable pressure ratings and installation requirements for the specific service fluid.
