Mueller Industries 3/4" OD Copper Tubing
This Mueller Industries refrigeration tubing is manufactured from 99% pure copper and annealed for ready bending during installation. It is designed for HVAC and refrigeration professionals who require reliable, dehydrated coil for system assembly or repair. The 50 ft length suits residential and light commercial projects.
Replaces field-cut lengths and non-standard coils
The tubing meets ASTM standard B-280, so it upgrades from generic uncertified coil when code compliance or material purity is required. The jump is worth it when a project demands nitrogen-urged, capped and shrink-wrapped tubing that arrives clean and moisture-free for immediate use.
Fits standard 3/4 inch OD flare
Each coil is cleaned, nitrogen urged, capped with standard yellow caps and shrink-wrapped to an air-tight seal, reducing prep time on site. The annealed temper allows tight bends without special tooling, freeing up workflow for brazing and pressure testing. Supplied in a single box for easy handling.

Questions about this item
What outer diameter must my fittings match for this 3/4" OD tubing?
The tubing has a 3/4 inch outside diameter, so all flare or compression fittings must be sized for 3/4 inch OD to seal correctly.
What is the correct way to uncoil the 50 ft length without kinking the annealed copper?
Lay the coil flat, secure one end, and walk the tubing off the coil in a straight line rather than pulling it sideways, which prevents work-hardening bends.
When should the yellow end caps be removed and replaced during a long installation?
Keep the factory caps on until each joint is ready to be brazed; if the tube sits open overnight, recap it to keep moisture and debris out of the cleaned interior.
