The VALUE COLLECTION 453-003NL is a red brass pipe tee designed for threaded plumbing and piping assemblies. This Class 125 fitting connects three sections of pipe at a 90-degree branch using male pipe thread (MPT) ends on all three ports. It carries a pressure rating of 125 psi, making it suitable for low- to medium-pressure water, air, and compatible fluid systems. The red brass construction provides good corrosion resistance in both potable water and general industrial piping applications. Licensed plumbers and pipefitters are the primary installers for this type of fitting in new construction and repair work.
This tee is used in residential and light commercial plumbing systems where a threaded branch connection is needed on a 1/2 inch pipe run. Typical applications include domestic water distribution, compressed air lines, and hydronic heating systems operating within the Class 125 pressure range. The MPT end connections thread directly into female-threaded fittings, valves, or pipe without additional adapters.
Designed as an OEM-style replacement or new-installation fitting compatible with standard 1/2 inch NPT threaded piping systems rated at Class 125 or lower.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements. Shut off and depressurize the affected water or air line completely before threading in or removing any fittings. Apply thread sealant tape or pipe dope to the male threads before assembly to ensure a leak-free joint. Do not overtighten threaded brass fittings, as brass is softer than steel and the threads can be damaged.
