Mueller Industries 456-004NL Push Fit Ball Valve 3/4 in

Product Description

The MUELLER INDUSTRIES 456-004NL is a 3/4-inch no-lead, DZR forged brass push-fit ball valve designed for water supply shutoff applications in residential and light commercial plumbing systems. The Instaloc II push-fit connection eliminates the need for soldering, threading, or crimping, allowing fast field installation without open flame. Rated at 200 CWP with a maximum operating temperature of 250 degrees F, this valve meets ASSE 1061 standards for push-fit fittings and is built to no-lead compliance requirements for potable water service.

This valve is well suited for residential new construction, renovation, and service work where a reliable, code-compliant shutoff is needed on 3/4-inch water lines. The push-fit design is especially practical in retrofit and repair scenarios where torch work is not ideal or permitted. Licensed plumbers and pipefitters are the primary installers, though the tool-free connection method also suits qualified service technicians working on appliance hookups and fixture supply lines.
