Oatey oat-38542 Washing Machine Outlet Box F1807 Pex

Product Description

The OATEY oat-38542 is a QUADTRO washing machine outlet box designed for recessed wall installation of supply valves and a waste drain. Built for both residential and commercial applications, this outlet box includes a 1/4 turn hammer valve and is configured to the ASTM F1807 PEX connection standard. The plastic box construction keeps weight low and resists corrosion. The unit also accommodates water hammer arrestors on supply lines serving quick-closing valves, addressing a common code requirement during washing machine rough-in. Licensed plumbers typically install this box during new construction or remodel work.

This outlet box is suited for laundry room installations in residential homes and light commercial buildings where supply and drain connections must be recessed into the wall cavity. The F1807 PEX connection type makes it compatible with crimp-ring PEX tubing systems. The faceplate finishes the wall opening cleanly, and the 2-inch drain opening aligns with standard washing machine drain line sizing. It is commonly installed during rough-in framing stages before drywall is applied.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable plumbing code, including IPC and local amendments.
