Mueller Industries KH02010 Copper Water Tube Type K 3/8 in Od

Product Description

The MUELLER INDUSTRIES KH02010 is a Type K copper water tube manufactured from C12200 phosphorus-deoxidized copper. It measures 3/8 inch outside diameter with a 1/4 inch nominal size, 0.25 inch inside diameter, and a 0.035 inch wall thickness. The tube ships in a 10-foot straight length and weighs approximately 0.145 pounds per foot, totaling 1.45 pounds. Type K designation indicates the heaviest wall thickness in the standard copper tube series, making it suitable for demanding underground and general plumbing service. Licensed plumbers and HVAC technicians install this tube in potable water supply, hydronic heating, and refrigeration-adjacent applications.

This tube is used in residential and light commercial plumbing systems where Type K copper is specified or required by local code. Common applications include underground water service lines, in-slab installations, and above-ground domestic hot and cold water distribution. Its C12200 alloy composition and conformance to ASTM B88 and NSF 61G make it appropriate for potable water contact. The 10-foot straight length is well suited for above-grade rough-in work and short service runs where coiled tube is not preferred.

Key Features

• Type K wall thickness (0.035 inches) provides the heaviest wall in the standard copper tube series for added durability
• C12200 phosphorus-deoxidized copper alloy resists corrosion in water service applications
• Meets ASTM B88, NSF 61G, and UNS C12200 standards for potable water use
• 3/8 inch OD with 0.25 inch ID — straight 10-foot length ready for cut-to-fit installation
• 0.145 pounds per foot weight allows straightforward handling and bending with standard tube benders

Compatibility

Designed as an OEM-style replacement and standard-supply copper tube for residential and commercial plumbing systems requiring Type K copper per ASTM B88 specification in 3/8 inch outside diameter.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off and drain the water supply before cutting into an existing line. Use a sharp tube cutter to produce a clean, square cut, and ream the cut end before soldering or making a compression fitting connection. Avoid over-bending without a proper tube bender, as kinking will compromise flow and structural integrity.
