Mueller Industries, Inc. LH10005 Straight Copper Tubing, 1 1/8 in OD, 5 ft, Type L

Straight Copper Tubing for Potable Water Systems

This seamless Type L copper tubing is made to ASTM B88 and NSF standards for potable water installations. It suits professional plumbers and qualified DIYers running supply lines that require 1 1/8 inch outside diameter and hard temper. The five-foot straight length reduces joints on longer runs. It is not for buyers who need pre-cleaned and capped tube or a softer temper for tight bends without fittings.

Build Quality and Daily Implications

Fabricated from C12200 copper with a .05 inch wall, the tube withstands 395 psi at 200 degrees F and 400 degrees F maximum temperature. The hard temper holds shape during layout but requires proper bending tools or fittings for direction changes. No coating or factory cleaning is applied, so the installer must prepare ends before soldering or pressing. The straight form stores flat and feeds cleanly through joists and studs.

Compatibility Checks Before Ordering

Verify that your design calls for Type L dimensions and hard temper rather than Type M or soft coil. Confirm the 1 1/8 inch outside diameter matches your fittings and that local code accepts ASTM B88 and NSF 372 or 61 listings. Ensure you have the tooling to cut, deburr and join bare copper ends on site. This product is restricted from sale in certain states; check local availability before specifying.
