Midland Industries P-03622 Dishwasher Adapter Brass Fitting

Product Description

The MIDLAND INDUSTRIES P-03622 is a brass dishwasher adapter fitting designed to transition between a 1/2-inch female compression inlet and a 3/8-inch compression outlet. This compact fitting is used to connect a dishwasher supply line to a standard household water supply valve or stub-out. Constructed from brass, it provides reliable corrosion resistance in wet, under-sink environments. The compression-style connections on both ends allow for a tool-assisted, leak-resistant seal without soldering. Plumbers and plumbing contractors install this fitting during dishwasher hookups, appliance replacements, or kitchen remodels where supply line size transitions are required.

This adapter is suited for residential kitchen plumbing applications, specifically where a 1/2-inch supply line or valve needs to reduce down to a 3/8-inch compression connection for a dishwasher inlet. It fits into tight under-sink spaces given its compact profile measuring approximately 0.75 inches in length, 0.85 inches in width, and 0.8 inches in height. It is appropriate for new dishwasher installations and appliance swap-outs where existing supply lines require an adapter to match the appliance inlet size.

Compatibility

Installation Notes

A licensed plumber or qualified tradesperson should install this fitting in accordance with the applicable International Plumbing Code (IPC) requirements. Shut off the water supply at the main or local stop valve and relieve line pressure before beginning work. Hand-tighten compression fittings first, then use an appropriately sized wrench to snug the compression nut - do not overtighten, as brass compression fittings can crack. After installation, restore water supply and inspect all connections for leaks before closing the cabinet.
