Product Identity

Mueller Industries MH04002 is a straight copper tube made to ASTM B88 Type M specifications. It suits plumbers and HVAC technicians who need a short, rigid length for water distribution or refrigerant lines. The 2 ft piece is ready to cut, bend or flare on site without additional preparation.

Capacity And Headroom

The tube has a 1/2 in nominal size with a .5 in inside diameter and 5/8 in outside diameter. Wall thickness of .028 in supports a maximum pressure of 850 psi, covering typical residential water service and many low-pressure refrigerant circuits. At 400 °F the material reaches its rated temperature limit, so steam or high-temperature hydronic loops beyond that point are outside the safe envelope.

Deciding Specification

Type M wall thickness is the single figure that determines whether this length meets local code for the intended pressure class. Thicker Type L or K tubing would be required where codes mandate a heavier wall for the same nominal diameter.

Questions about this item

Will the 5/8 in. OD copper tubing join my existing 1/2 in. nominal fittings without adapters?

Yes, the 5/8 in. outside diameter matches standard 1/2 in. nominal copper fittings, so it slides directly into sweat or compression joints you already have.

How can I verify the tubing meets the 850 psi rating after installation?

Pressurise the system to its working pressure and inspect every joint for leaks; the Type M wall of 0.028 in. and ASTM B88 compliance ensure the tube holds 850 psi when joints are sound.

Does the 2 ft straight length come with any fittings, flux or insulation, or must I buy them separately?

The box contains only the bare 2 ft straight copper tube; couplings, solder, flux and any insulation must be purchased separately.
