Product identity

The Apollo CPVCMU1234 is a brass male NPT union that joins a 3/4 inch threaded connection to a 1/2 inch CPVC solvent-weld socket. It suits plumbers and facility managers who need a reliable transition between metal pipe threads and CPVC piping in bathware installations.

Interface limits

The union relies on a solvent-weld joint for the CPVC side, which requires clean pipe ends, proper primer and cement, and adequate cure time before pressure testing. The brass MNPT threads demand compatible thread sealant and careful tightening to avoid cracking the CPVC socket or stripping the fitting.

Upgrade context

This fitting replaces a direct threaded adapter when a detachable union connection is preferred for maintenance access or future reconfiguration. The jump is worth it when the system design calls for periodic disassembly without cutting pipe, rather than a permanent solvent-weld or threaded joint.

Questions about this item

Which size combination fits my CPVC piping?

The fitting joins a 3/4 in. brass male NPT union to a 1/2 in. solvent-weld CPVC socket for a direct transition.

How does the brass MNPT union perform once installed?

The brass male NPT threads seal against a female NPT fitting while the CPVC end solvent-welds for a permanent joint.

What thread standard does the union use and what does it limit?

It uses male NPT threads, which limit the connection to matching female NPT fittings and require thread sealant for a leak-free seal.
