The MIDLAND INDUSTRIES 285PPC-12MM is a 12 mm push-to-connect cap designed to terminate or seal open push-to-connect ports in composite plumbing and fluid system assemblies. Constructed from composite material, this cap supports working pressures up to 220 psi and an operating temperature range of -5 to 175 degrees F. Its push-to-connect design allows fast, tool-free installation, making it well suited for service calls where speed and reliability matter. Licensed plumbers, pipefitters, and mechanical contractors working on residential and light commercial systems are the primary installers.
This cap is used to plug unused or open 12 mm push-to-connect ports on piping networks, manifolds, or fluid distribution systems. Its composite body construction makes it appropriate for applications where a lightweight, corrosion-resistant fitting is preferred over a traditional brass body. Typical scenarios include capping branch lines during phased installations, isolating a portion of a system for service, or permanently terminating an unused outlet.
Designed as an OEM-style replacement or service fitting for 12 mm push-to-connect composite body plumbing systems.
Installation is performed by a licensed plumber or qualified mechanical contractor. Depressurize and drain the system before removing or capping any fitting. Ensure the tubing or port end is clean and free of burrs before inserting into the push-to-connect cap. Follow all applicable IPC and local plumbing code requirements for fitting selection and system testing after service.
