Rwc 22786A 4-port Pex Barb Flow-through Manifold

Product Description

The RWC 22786A is a four-port, flow-through open manifold designed for PEX distribution systems in residential and light commercial plumbing. Built from copper, it features a 3/4 inch PEX barb inlet and exit with four 1/2 inch PEX barb outlet ports. The manifold is rated for a maximum working pressure of 200 psi and a maximum working temperature of 200 degrees F, making it suitable for both hot and cold water supply lines. NSF listed for potable water applications, this fitting is intended for installation by licensed plumbers working with PEX tubing systems.

This manifold is used in residential and light commercial hydronic or domestic water distribution where multiple branch lines must be served from a single supply. Common install scenarios include under-sink multi-outlet runs, home run PEX layouts, and fixture rough-in work where a centralized distribution point is needed. The four-port configuration suits smaller zoned layouts or localized branch manifold setups.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before making any connections. PEX barb fittings require appropriate clamp rings or crimp rings and the correct crimping or clamping tool for a secure, leak-free connection. Inspect all barb connections after pressurizing the system before closing in walls or enclosures.
