Mueller Industries LH03002 Type L Copper Water Tube

Product Description

The MUELLER INDUSTRIES LH03002 is a Type L copper water tube rated for potable water and hydronic plumbing applications. Made from Grade C12200 phosphorus-deoxidized copper, this tube measures 0.500 inches outside diameter with a 0.375 inches inside diameter and a 0.035 inches wall thickness. The 2-foot length suits short runs, stub-outs, and repair segments where a full straight length is unnecessary. Plumbers and HVAC technicians rely on Type L copper for its balance of wall thickness and flexibility across residential and light commercial installations. The material conforms to ASTM B88 and NSF 61G, meeting standard requirements for drinking water system components.

This tube is suited for residential and commercial potable water supply lines, hydronic heating distribution piping, and general plumbing repair work. Its 2-foot cut length is practical for fixture connections, short branch lines, and service calls where a minimal material run is needed. The 3/8 inch nominal size is a common dimension in residential water supply branch lines serving sinks, dishwashers, and similar fixtures. Licensed plumbers and HVAC technicians are the primary installers in jurisdictions governed by the IPC and applicable state plumbing codes.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable edition of the International Plumbing Code and local amendments. Shut off and depressurize the water supply before cutting or joining this tube. Use a sharp tube cutter to produce a clean, square cut and ream the end to full inside diameter before soldering, pressing, or applying compression fittings. Do not use open-flame soldering near combustible materials without proper shielding, and allow joints to cool fully before restoring system pressure.
