The ASC ENGINEERED SOLUTIONS 300052404 is a black cast iron reducing tee designed for threaded pipe systems in commercial and industrial plumbing applications. This fitting transitions from a 2.5-inch run to a 1.5-inch branch outlet, allowing flow to be redirected or split at a reduced diameter. The black coating provides corrosion resistance suitable for gas distribution, fire suppression, and standard water piping systems. At 5.19 pounds, the cast iron construction delivers the durability and pressure ratings demanded in mechanical rooms and rough-in installations. Licensed plumbers and pipefitters are the primary installers of this fitting type.
This reducing tee is suited for residential and commercial piping systems where a branch connection at a smaller diameter is required. Common applications include black iron gas piping, hydronic heating distribution, and industrial process lines. The 2.5-inch by 1.5-inch configuration is a standard reducing size used in branch take-offs throughout mechanical and utility installations. Domestic manufacture supports consistent thread quality and material integrity.
Designed as an OEM-style replacement or new-installation fitting for threaded black iron pipe systems requiring a 2.5-inch by 1.5-inch reducing tee connection.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements. Shut off and depressurize the line before disassembling or connecting any threaded fittings. Apply approved pipe thread sealant or PTFE tape to male threads before assembly. Do not overtighten; use a pipe wrench and backup wrench to avoid stressing adjacent fittings or valves.
