Matco-norca zmbtr060506 Reducing Tee Class 150 Black Malleable Iron

Product Description

The MATCO-NORCA zmbtr060506 is a reducing malleable iron tee fitting rated for Class 150 service. It connects pipes in a branch configuration with a 1-1/4 inch run on both ends and a 1 inch branch outlet. All three ports are female threaded for standard pipe thread connections. The fitting is manufactured from Chinese malleable iron meeting ASTM A197/A197M material specifications and carries a black finish. It is rated to 550 degrees F and meets multiple industry standards including ASME B16.3 and ANSI requirements. Plumbers and pipefitters install this fitting in low-pressure gas, water, and industrial piping systems.

This reducing tee is suited for residential and light commercial piping applications where a branch line of smaller diameter must be taken off a main run. Typical installations include gas distribution piping, fire protection systems, and general industrial plumbing where a threaded branch connection at a reduced size is required. The black finish identifies it as suitable for gas piping use in many jurisdictions. It is installed by licensed plumbers or pipefitters in systems governed by the International Plumbing Code or International Fuel Gas Code.

Key Features

• Reducing configuration: 1-1/4 inch x 1 inch x 1-1/4 inch for branch size reduction on a common run

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Class 150 threaded malleable iron piping systems using standard NPT pipe threads.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with the International Plumbing Code or International Fuel Gas Code, as applicable. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply listed thread sealant or PTFE tape to male threads before assembly and tighten to a wrench-tight fit. Pressure-test the completed assembly per local code requirements before returning the system to service.
