Asc Engineered Solutions 300055407 Reducing Tee Cast Iron Class 125

Product Description

The ASC ENGINEERED SOLUTIONS 300055407 is a cast iron reducing tee rated for Class 125 service in threaded piping systems. It features female NPT (FNPT) connections on all three ports and is sized at 2-1/2 inches x 1-1/4 inches x 2-1/2 inches, making it suitable for branch reductions in main lines. The fitting handles a maximum working pressure of 175 psi across a temperature range of -20 degrees F to 150 degrees F, and carries a saturated steam pressure rating of 125 psi. Licensed plumbers and pipefitters install this fitting in commercial and industrial piping layouts where a threaded branch connection at a reduced diameter is required.

This reducing tee is designed for use in wet pipe systems, general plumbing distribution lines, and fire protection piping where Class 125 cast iron threaded fittings meet the project specification. It is well suited for both new construction and retrofit work in commercial buildings where reducing branch connections are required in 2-1/2 inch mains. The FNPT thread form on all three ports allows direct connection to standard NPT-threaded pipe and valves without adapters.

Compatibility

Designed as an OEM-style threaded reducing tee for Class 125 cast iron piping systems using NPT-threaded pipe and fittings per ASME B16.4 standards.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes, including IPC and NFPA 13 where fire protection piping is involved. Depressurize and drain the piping system completely before cutting into any existing line. Apply thread sealant or PTFE tape to the male NPT threads of the mating pipe per standard practice. Do not exceed the rated working pressure or temperature limits for this fitting.
