The NIBCO INC T00055C is a 1-inch CPVC coupling designed to join straight lengths of CPVC tubing in residential and light commercial plumbing systems. This fitting provides a secure, leak-resistant connection between two sections of CPVC pipe and is finished in a standard beige color consistent with CPVC material conventions. Weighing 0.68 pounds per unit, it is a compact, durable fitting suited for hot and cold water distribution lines where CPVC piping is specified. Licensed plumbers and pipefitters install this type of coupling during new construction, system expansion, or repair work on CPVC water supply systems.
This coupling is used in residential and light commercial plumbing applications where CPVC tubing is the specified pipe material. Typical installations include domestic hot and cold water supply lines, as well as retrofit or repair scenarios where a straight inline connection is needed. The 1-inch size suits main distribution lines and branch runs commonly found in residential construction. Sold in packages of 10 units, it is a practical choice for contractors stocking fittings for multiple installations on a single job site.
Designed as an OEM-style replacement and standard-use fitting for 1-inch CPVC tubing systems in residential and light commercial plumbing installations.
Installation is performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines for CPVC solvent-cement joints. Shut off the water supply and depressurize the line before cutting or fitting. Clean and deburr pipe ends, apply CPVC-compatible primer and solvent cement per the manufacturer instructions, and allow adequate cure time before restoring water pressure. Do not use this fitting with PVC pipe or non-CPVC solvent cements.
