Merit Brass MB23260 Copper Male Adapter 1/2 in Press X Npt

Product Description

The MERIT BRASS MB23260 is a 1/2-inch copper male adapter press fitting designed for plumbing installations that require a transition from a press-style pipe connection to a threaded male NPT end. The fitting uses a push-to-connect press mechanism on one end and a standard NPT male thread on the other, eliminating the need for soldering or open flame at the press side. It is rated for a maximum working pressure of 300 psi and a maximum temperature of 250 degrees F, making it suitable for domestic water supply, hydronic heating, and light commercial plumbing systems. Licensed plumbers and pipefitters are the primary installers of this fitting type.

The MB23260 is used in residential and light commercial plumbing applications where copper piping transitions to threaded connections, such as connections to valves, fixture supply lines, or threaded nipples. Its lead-free copper construction and compliance with NSF-61/372 make it appropriate for potable water systems. The press end accommodates 1/2-inch copper tubing, and the male NPT thread connects to standard female-threaded fittings or valves in the same size class.

Key Features

• Press x male NPT thread end connection eliminates soldering on the press side
• Rated to 300 psi maximum working pressure for reliable service in pressurized water lines
• Maximum working temperature of 250 degrees F suitable for hot water and hydronic applications
• Lead-free copper construction meets NSF-61/372 and IAPMO PS117 requirements for potable water use
• 1/2-inch fitting size covers one of the most common residential and light commercial pipe sizes
• No flux, solder, or torch required on the press end, reducing labor time and open-flame risk

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 1/2-inch copper press piping systems using standard NPT-threaded male connections in residential and light commercial plumbing.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the water supply line before installation. The press end requires a compatible press tool and jaw set rated for copper press fittings — do not attempt to seat the press connection by hand or with non-rated tooling. Verify that the male NPT thread connection is properly taped with PTFE thread seal tape or pipe dope before assembly to prevent leaks.
