Homewerks Worldwide 544-34-34-B Cpvc Transition Union

Product Description

The HOMEWERKS WORLDWIDE 544-34-34-B is a low-lead CPVC transition union designed to connect metal female pipe threads to CPVC piping in hot water systems. The fitting solvent welds directly to CPVC tube on one end and threads onto a standard female iron pipe (FIP) connection on the other. Its engineered design accounts for the difference in thermal expansion coefficients between CPVC and metal pipe, preventing stress cracking and joint failure in high-temperature water applications. Lead content on wetted surfaces is held to no more than 0.25% weighted average, meeting low-lead compliance requirements. Licensed plumbers and pipefitters are the primary installers of this fitting.

This transition union is suited for residential and light commercial plumbing applications where a CPVC hot water distribution line must connect to a metal threaded component such as a water heater, valve, or manifold. The union-style design allows the piping system to be disassembled without cutting pipe, which simplifies future service, repairs, or component replacements. The 3/4-inch MIP by 3/4-inch CPVC configuration handles standard trunk-line and branch-line sizing common in residential hot water systems.

Key Features

• Transitions from metal female pipe threads to CPVC tube via solvent weld connection
• Compensates for thermal expansion coefficient differences between CPVC and metal in hot water service
• Low-lead compliant — no more than 0.25% weighted average lead content on wetted surfaces
• Union design permits disassembly of the piping system without cutting
• 3/4-inch MIP by 3/4-inch CPVC sizing for standard residential distribution lines

Compatibility

Designed as an OEM-style replacement and new-installation fitting for residential and light commercial CPVC hot water piping systems requiring a transition to standard female metal pipe threads.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and depressurize the line before beginning work. Apply CPVC-rated solvent cement to the CPVC socket end per the cement manufacturer's instructions, and use thread sealant rated for hot water service on the metal threaded connection. Do not use PVC solvent cement in place of CPVC-rated cement, as it will not provide adequate bond strength for hot water service temperatures.
