Midland Industries 746440MH 3-way Supply Stop Compression

Product Description

The MIDLAND INDUSTRIES 746440MH is a lead-free, 3-way supply stop valve designed for plumbing supply line applications where a single inlet must feed two outlets simultaneously. Built with a brass body and chrome-plated finish, this quarter-turn valve connects via compression fittings on all three ports: one 5/8-inch inlet and two 3/8-inch outlets. The PTFE seat provides a reliable, drip-free seal, and the mini brass handle allows for quick shutoff in tight under-sink or vanity cabinet installations. At 0.29 pounds, it is compact enough for confined spaces without sacrificing durability. Licensed plumbers and experienced DIYers install this valve in residential supply applications.

This 3-way supply stop is suited for residential plumbing installations where two fixtures or appliances must be served from a single supply line. Typical installations include under-sink setups where both a faucet and a dishwasher, filtration system, or ice maker require a shared water supply connection. All three ports use compression connections, making this valve compatible with standard soft copper or braided supply tubing without soldering. The chrome-plated finish blends with most under-sink hardware.

Installation Notes

Installation should be performed by a licensed plumber or qualified tradesperson in accordance with applicable local plumbing codes and the IPC. Shut off the main water supply and relieve line pressure before removing any existing valve or fitting. Compression fittings require a tubing cutter for clean, square cuts and should be hand-tightened then snugged with a wrench - do not overtighten, as this can crack compression ferrules. Confirm all connections are leak-free under pressure before returning the supply to service.
