Mueller Streamline KIT09281 Ac Line Set 3/8x3/4 30ft

Product Description

The MUELLER STREAMLINE KIT09281 is a pre-insulated split-system AC line set designed for residential and light commercial air conditioning installations. It consists of a 3/8-inch liquid line and a 3/4-inch suction line, both running 30 feet in length and wrapped with 3/8-inch elastomeric insulation. The set ships with plain ends and no flare fittings, giving the installing technician full control over the termination method. No control wire is included. This line set is handled and installed by licensed HVAC technicians during split-system equipment changeouts or new installations.

This line set suits standard residential split-system air conditioners and heat pumps where the air handler or evaporator coil is located up to 30 feet from the condensing unit. The 3/8-inch liquid line and 3/4-inch suction line sizing is common for systems in the 2-to-5-ton range. Plain-end tubing allows the technician to cut, deburr, and connect using the fitting style required by the job, whether brazed or flared. The pre-bent coil configuration simplifies routing in typical residential applications.

Key Features

• 30-foot run length covers typical residential split-system installations
• 3/8-inch liquid line and 3/4-inch suction line in a single pre-insulated set
• 3/8-inch elastomeric insulation on suction line reduces condensation and heat gain
• Plain ends allow technician-selected termination: brazed or flared connections
• No flare fittings included, keeping the kit adaptable to job-specific hardware
• No control wire included — run communication or thermostat wire separately as required

Compatibility

Designed as a standard OEM-style replacement or new-installation line set for residential split-system air conditioners and heat pumps requiring 3/8-inch liquid and 3/4-inch suction line sizing over a 30-foot run.

Installation Notes

Licensed HVAC technicians should recover all refrigerant and de-energize the system at the disconnect before disconnecting or replacing line sets, in accordance with EPA Section 608 requirements. Tubing ends should be cut cleanly, deburred, and kept capped until connection to prevent moisture and debris contamination. Brazed connections require a nitrogen purge during the brazing process to prevent oxide scale inside the copper lines. After installation, pressure-test and leak-check per equipment manufacturer and local mechanical code requirements before recharging the system.
