Mueller Industries MUE-61420250 Refrigerant Line Set 25 Ft

Product Description

The MUELLER INDUSTRIES MUE-61420250 is a standard refrigerant line set designed for residential and light commercial HVAC installations. It consists of a 3/8-inch liquid line paired with a 7/8-inch suction line, with the suction line insulated to 1/2-inch thickness. Total line set length is 25 feet. The copper tubing is manufactured under the Streamline product line, which has served the HVAC trade for decades. This line set handles refrigerant transport between the condensing unit and the evaporator coil, and is installed by licensed HVAC technicians as part of split-system air conditioning and heat pump installations.

This line set is suited for standard split-system and mini-split HVAC applications where a 3/8-inch liquid line and 7/8-inch suction line configuration is required. The 25-foot length covers typical residential installations where the air handler or evaporator coil is located a moderate distance from the outdoor condensing unit. The pre-insulated suction line reduces field labor and helps maintain system efficiency by limiting heat gain on the low-pressure side of the refrigerant circuit.

Key Features

• 3/8-inch liquid line and 7/8-inch suction line configuration for standard split-system sizing
• Suction line insulated with 1/2-inch black insulation to minimize heat gain and condensation
• 25-foot length suitable for typical residential split-system runs
• Copper tubing construction meets refrigerant-grade quality and consistency standards
• Compatible with standard split-system and mini-split installations

Compatibility

Designed as an OEM-style replacement or new-installation line set for residential and light commercial split-system air conditioners and heat pumps requiring a 3/8-inch liquid line and 7/8-inch suction line configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with applicable mechanical codes. Shut down and recover all refrigerant from an existing system before disconnecting or replacing line sets. Braze connections using nitrogen purge to prevent internal oxidation scale, and leak-test all joints before recharging the system. Support the line set at regular intervals to prevent sagging and vibration wear over time.
