The ASC Engineered Solutions 15M.WFT is a brass mechanical tee fitting designed for use in piping assemblies where a branch connection is required. Built to a 1/2 inch nominal size with male NPT (MNPT) end connections, this tee allows a technician to tap into an existing line or create a three-way junction without welding or soldering. The all-brass construction provides corrosion resistance and durability suitable for both gas and fluid service applications. Plumbers and pipefitters commonly specify brass MNPT fittings for their thread reliability and long service life in demanding mechanical systems.
This mechanical tee is suited for residential and light commercial plumbing, gas distribution, and HVAC piping where a 1/2 inch nominal branch connection is needed. The MNPT end style threads directly into female-threaded ports, valves, or fittings, making it a straightforward component in new construction and retrofit work. Its domestic manufacture supports compliance requirements on projects that specify domestically produced materials.
Designed as an OEM-style replacement and standard-fit mechanical tee for 1/2 inch nominal MNPT piping systems in residential and light commercial plumbing and gas applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IPC, or IFGC requirements depending on the service type. Shut off and depressurize the line completely before threading or removing any fittings. Apply appropriate thread sealant or PTFE tape to all MNPT connections and tighten to a wrench-tight fit. Do not over-torque brass fittings, as this can crack the fitting body.
