The NIBCO INC T00070D is a 3/4-inch CPVC male iron pipe thread (MIP) adapter designed for cold water plumbing applications. This fitting connects CPVC pipe to threaded pipe fittings or female-threaded components, making it a standard transition piece in residential and light commercial water supply systems. Rated for cold water use only, the T00070D is not suitable for hot water or hydronic heating lines. Licensed plumbers and pipefitters install this adapter during new construction and retrofit work where CPVC transitions to threaded iron or brass pipe connections are required.
This adapter is used in cold water distribution systems where CPVC piping meets threaded metal or plastic female fittings. Typical applications include potable water supply lines, cold water branch connections, and fixture rough-in work. It is sold in a package of 25 units, making it practical for jobsite stock or contractor supply. Its use is limited strictly to cold water service; do not install on hot water, steam, or hydronic heating lines.
Designed as an OEM-style replacement and standard-fit CPVC adapter for cold water plumbing systems using 3/4-inch CPVC pipe with standard male iron pipe thread connections.
Installation of this adapter is performed by a licensed plumber in accordance with applicable plumbing codes such as the IPC. Shut off the water supply and depressurize the line before beginning any fitting work. CPVC solvent cement appropriate for CPVC-to-CPVC joints should be used on the socket end, and PTFE tape or an approved pipe thread sealant should be applied to the male threads before assembly. Do not overtighten threaded connections, as CPVC is susceptible to cracking under excessive torque.
