Mueller Industries D 04010P Seamless Copper Tube 1/4 in Od

Product Description

The MUELLER INDUSTRIES D 04010P is a seamless copper tube manufactured from Alloy 122 copper, measuring 10 feet in length with a 0.25-inch outside diameter and a 0.030-inch wall thickness. Alloy 122 copper is a phosphorus-deoxidized grade well suited for brazed and soldered connections. The seamless construction eliminates longitudinal seams, delivering consistent wall thickness and reliable pressure integrity throughout the tube. HVAC technicians, plumbers, and refrigeration mechanics use this tube for refrigerant lines, water supply runs, and instrumentation applications where a clean, burr-free bore is required.

This tube is appropriate for residential and light commercial applications including refrigerant suction and liquid lines, domestic water distribution, and OEM equipment fabrication. The 0.25-inch OD size is a common dimension in HVAC systems for capillary-style sensing lines, small refrigerant circuits, and condensate or pressure-sampling connections. Sold as a single 10-foot straight length, it is easy to cut and deburr in the field with standard tube cutters before bending or fitting.

Key Features

• Seamless construction for uniform wall thickness and consistent pressure rating
• Alloy 122 phosphorus-deoxidized copper is compatible with brazing and soldering
• 0.25-inch OD with 0.030-inch wall thickness and 0.190-inch inside diameter
• 10-foot straight length simplifies measuring and cutting to required run lengths
• Suitable for refrigerant, water, and instrumentation service lines

Compatibility

Designed as an OEM-style and field-service replacement or new-installation tube for residential and light commercial HVAC, plumbing, and refrigeration systems requiring 1/4-inch OD seamless copper tubing.

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or refrigeration mechanic in accordance with applicable local codes, the International Fuel Gas Code, and ASHRAE standards for refrigerant piping. Isolate and recover any refrigerant or shut off the water supply before cutting into an existing line. Use a sharp tube cutter and a reamer or deburring tool to prepare the cut end before fitting or brazing. Do not use open-flame brazing near flammable materials without proper shielding and ventilation.
