Milwaukee Tool 49-16-2658NX Press Ring Jaw 4 Inch

Product Description

The MILWAUKEE TOOL 49-16-2658NX is a 4-inch press ring jaw designed as a replacement pressing head for copper pipe connections. It attaches to the M18 Force Logic Press Tool and applies the controlled radial force needed to complete a secure, leak-free ProPress-style fitting connection on 4-inch copper pipe. Weighing 12.3 pounds, this jaw is built for heavy-duty commercial and mechanical plumbing work where large-diameter copper press connections are required. Licensed plumbers and pipefitters rely on press tooling like this to eliminate open-flame brazing on larger copper runs, reducing fire risk and speeding up installation on occupied job sites.

This jaw is intended for use exclusively with the Milwaukee M18 Force Logic Press Tool on 4-inch copper pipe. It is suited for commercial plumbing systems, hydronic heating piping, and large-diameter domestic water distribution where copper press fittings are specified. The jaw handles a single pipe size — 4 inches — so it is a dedicated, task-specific replacement head rather than a multi-size accessory. It is appropriate for both new construction and retrofit mechanical rooms where copper press systems are already in use.

Installation Notes

Installation of press fittings on 4-inch copper pipe should be performed by a licensed plumber or pipefitter in accordance with the International Plumbing Code and the fitting manufacturer's requirements. De-energize or isolate the system and relieve line pressure before beginning any press connection work. Verify the jaw is fully seated and locked onto the press tool head before initiating a press cycle. Do not use this jaw on pipe sizes, materials, or fitting systems other than those specified by the manufacturer.
