Mueller Industries MH14010 Copper Water Tube Type M

Product Description

The MUELLER INDUSTRIES MH14010 is a Type M copper water tube manufactured from Grade C12200 phosphorus deoxidized copper. It measures 1-5/8 inches outside diameter with a 1.527-inch inside diameter and a 0.049-inch wall thickness, yielding a 10-foot straight length. At 0.94 pounds per foot, the 10-foot stick weighs approximately 9.4 pounds. Plumbers and pipefitters use Type M tube for domestic water supply, hydronic heating distribution, and light commercial plumbing systems where code permits the thinner M-wall profile. The tube meets ASTM B88 dimensional and mechanical standards as well as NSF 61G potable water contact requirements.

Type M copper tube in the 1-1/2-inch nominal size is a common choice for main water distribution lines, branch mains, and hydronic supply and return runs in residential and light commercial construction. The 10-foot straight length is standard for rough-in work where long, uninterrupted runs reduce the number of joints. C12200 alloy is fully compatible with standard copper solder fittings, press fittings, and compression fittings rated for this nominal size and wall type.

Key Features

• Grade C12200 phosphorus deoxidized copper for reliable solderability and corrosion resistance
• Type M wall profile — 0.049-inch wall thickness suits potable water and hydronic applications where M tube is code-accepted
• 1-5/8 inches OD / 1.527 inches ID for precise fit with standard 1-1/2-inch nominal copper fittings
• 10-foot straight length at 0.94 pounds per foot minimizes field joints on long runs
• Meets ASTM B88 and NSF 61G — listed for potable water contact

Compatibility

Designed for use with standard 1-1/2-inch nominal copper solder, press, and compression fittings rated for Type M tube per ASTM B88. Suitable for potable water systems where NSF 61G-listed materials are required.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable plumbing code, such as the IPC or local amendments, which govern where Type M copper wall thickness is permitted. Shut off and drain the water supply before cutting into any existing line. Use a sharp tube cutter to ensure a square cut, deburr the inside edge completely, and clean both tube and fitting contact surfaces before soldering, pressing, or assembling compression connections. Support spacing should follow code-specified hanger intervals for copper tube of this diameter.
