Anvil 0300045341 Black Cast Iron Tee Reducer Class 125

Product Description

The ANVIL 0300045341 is a black cast iron threaded tee reducer designed for use in piping systems where a branch reduction is required within a tee configuration. Sized at 1-1/2 x 1/2 x 1-1/2 inches with female pipe thread (FPT) connections on all ports using NPT threading, this fitting meets Class 125 pressure ratings for liquid and gas service up to 125 psi. It carries ASME B1.20.1 and ASME B16.3 dimensional standards, ASTM A-197 material compliance, FM Approval, and cULus Listing. Licensed plumbers and pipefitters install this fitting in fire protection, gas distribution, and general-purpose piping applications.

This reducer tee is suited for residential and commercial piping installations where a main run must continue at the same diameter while a smaller branch line is tapped off. The 1-1/2 inch run ports and 1/2 inch branch port make it a common choice for gas branch lines, hydronic heating distribution headers, and fire suppression system branch drops. All connections are threaded FPT per NPT standards, compatible with standard black iron pipe and fittings of the same class.

Installation Notes

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 piping system completely before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded connections, as cast iron fittings can crack under excessive torque.
