MILLENNIUM Straight Stop Valve

This MILLENNIUM straight stop valve connects a 5/8 inch OD compression inlet to a 1/2 inch OD compression outlet. It is a new bath faucet part designed for residential plumbing installations. The component regulates water flow to fixtures such as toilets or sinks. It is supplied directly from the manufacturer.

Suited for standard supply-line connections

This part suits plumbers and homeowners completing standard supply-line connections where the specified compression sizes match. It is not for systems requiring different inlet or outlet dimensions, alternative connection types such as sweat or push-fit, or installations needing an angle-stop configuration. Buyers who want more storage or a different valve style should look elsewhere.

Handles typical residential shut-off duties

The valve comfortably handles typical residential shut-off duties for compatible fixtures. It runs out when the piping layout calls for a larger or smaller compression size, a threaded interface, or an angled body. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm. Orders of 75 or more ship free from the manufacturer.

Questions about this item

Which supply line size must already be in place for the 5/8" OD compression inlet to connect?

A 5/8" OD supply tube is required for the inlet side of this straight stop.

Will the 1/2" OD compression outlet mate with the existing fixture supply nut I plan to keep?

Yes, the outlet accepts a 1/2" OD tube or riser, matching standard fixture supply connections.

How can I verify the stop is sealing properly after installation?

Pressurise the line and inspect both compression joints for any moisture; a dry joint confirms correct seating.
