Merit Brass MB70010 3/4 Inch Copper Ball Valve Push-to-connect

Product Description

The MERIT BRASS MB70010 is a 1-piece, full-port ball valve built for shutoff and flow control in plumbing and mechanical systems. The copper body connects via push-to-connect press ends, making it compatible with press-fit installation workflows that eliminate open-flame soldering. A stainless steel lever handle provides positive quarter-turn operation. The valve is rated to 300 psi maximum working pressure and handles temperatures from 0 degrees F to 250 degrees F, making it suitable for both cold and hot water service lines. EPDM seals maintain integrity across the full rated temperature range. The valve carries NSF-61/376 and IAPMO Z1157 listings and is certified lead free.

This valve is suited for residential and light commercial plumbing installations where press-fit copper systems are specified. Typical applications include domestic hot and cold water supply lines, hydronic heating distribution, and mechanical room shutoff points where no-flame installation is required or preferred. The 3/4 inch pipe size fits standard 3/4 inch copper tube with an outside diameter of 1.252 inches. The full-port design minimizes flow restriction, which is important in applications where pressure drop must be kept low.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements. Shut off the water supply and depressurize the line before installation. Press-fit connections require a compatible press tool and the correct jaw set for 3/4 inch copper press fittings — verify tool compatibility before pressing. Inspect the tube end for squareness and remove burrs before inserting into the valve to ensure a proper seal.
