Mueller Industries KH05005 Type K Copper Tube 3/4 in Od

Product Description

The MUELLER INDUSTRIES KH05005 is a Type K copper water tube manufactured from Grade C12200 phosphorus-deoxidized copper. It measures 0.75 inches outside diameter with a 0.625-inch inside diameter and a 0.049-inch wall thickness, making it the heaviest-wall option among standard copper tube types. The 5-foot straight length is suited for underground water service, underground gas distribution, medical gas installations, and other applications where maximum pressure rating and corrosion resistance are required. Licensed plumbers and pipefitters are the primary installers of this product in both residential and light commercial settings.

Type K copper tube is the standard choice for underground water service lines where soil conditions, burial depth, or code requirements demand a heavier wall than Type L or Type M. This 5-foot section works well for short runs, connection points, stub-outs, and repair segments. The C12200 alloy designation confirms 99.9 percent copper content with a phosphorus deoxidizer, which makes the tube compatible with standard sweat, press-fit, and flare fittings used in potable water and hydronic systems.

Installation Notes

Installation of copper water tube should be performed by a licensed plumber in accordance with the International Plumbing Code and applicable local codes. Shut off the water supply and relieve system pressure completely before cutting into any existing line. Use a pipe cutter sized for 3/4-inch copper and ream cut ends to remove burrs before fitting assembly. For underground installations, verify burial depth and bedding requirements per local code before backfilling.
