Mueller Industries MH30010 Copper Water Tube Type M

Product Description

The MUELLER INDUSTRIES MH30010 is a Type M copper water tube manufactured from Grade C12200 phosphorus deoxidized copper. It measures 3-1/8 inches outside diameter with a 3.0 inch inside diameter and a 0.072 inch wall thickness, in a 10-foot length. At 2.68 pounds per foot, the total unit weight is approximately 26.8 pounds. Type M copper tube is widely used in potable water distribution, hydronic heating systems, and general plumbing supply lines. Installation is performed by licensed plumbers and pipefitters in both residential and light commercial applications.

This tube is suited for interior potable water supply, recirculation systems, and hydronic radiant or baseboard heating installations. The 3-inch nominal size targets larger branch and main supply lines where adequate flow volume is required. The straight 10-foot length simplifies cutting to field dimensions. Plumbers select Type M copper for its balance of wall thickness, weight, and compatibility with standard soldered or press-fit fittings used throughout the trade.
