The MATCO-NORCA zmbt00 is a black malleable iron pipe tee designed for use in threaded piping systems where a branch connection is needed at a 90-degree angle from the run. Rated at 150 lb pressure class with a maximum working pressure of 300.23 psi, this fitting handles a wide service temperature range of -20 to 151 degrees F. At 1/8 inch nominal size and 1.38 inches in length, it fits compact piping runs in gas, air, and compatible fluid distribution systems. Plumbers and pipefitters install this type of fitting as part of new construction or retrofit work on low-pressure threaded iron pipe systems.
This tee is suited for residential and light commercial applications involving threaded black iron pipe. Typical uses include natural gas distribution lines, compressed air systems, and other services compatible with malleable iron and black finish fittings. The 1/8 inch nominal size makes it appropriate for small-diameter branch connections in tight spaces or at instrument and gauge tap locations. It carries the PL-0317-F series designation and is sourced as an import product.
Designed as an OEM-style replacement or new-installation fitting for 1/8 inch nominal threaded black iron pipe systems rated at 150 lb pressure class.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes including the International Fuel Gas Code or International Plumbing Code as relevant to the service. Shut off and depressurize the pipe system completely before disassembling or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded connections in malleable iron fittings, as cracking or thread damage can result.
