Mueller Streamline 100000181 Lineset 3/4 X 3/8 in 30 Ft Insulated

Product Description

The MUELLER STREAMLINE 100000181 is a pre-insulated refrigerant lineset used to connect an outdoor condensing unit to an indoor evaporator coil in split-system air conditioning and heat pump installations. The set consists of a 3/4-inch suction line and a 3/8-inch liquid line, each wrapped in insulation to reduce heat gain and condensation. The 30-foot length covers typical residential installations where the indoor and outdoor units are separated by a standard run. HVAC technicians use this lineset during new system installations or when replacing deteriorated copper line sets.

This lineset is suited for residential and light-commercial split-system HVAC applications. The 3/4-inch suction line diameter and 3/8-inch liquid line diameter correspond to common sizing for mid-range residential cooling systems. The 30-foot pre-cut length reduces field labor compared to sourcing bulk tubing and cutting to length on site. It is typically installed through walls, ceilings, or conduit chases between the air handler or furnace coil cabinet and the outdoor condensing unit.

Key Features

• 3/4-inch suction line and 3/8-inch liquid line in a single pre-paired set
• 30-foot length suitable for standard residential split-system runs
• Pre-installed insulation on both lines reduces heat gain and condensation on the suction line
• Copper construction compatible with common refrigerants used in residential split systems
• Pre-cut length reduces job-site fabrication time

Compatibility

Designed as an OEM-style replacement or new-installation lineset for residential split-system air conditioners and heat pumps requiring a 3/4-inch suction line and 3/8-inch liquid line configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes and EPA Section 608 refrigerant handling requirements. Power down the system at the disconnect and indoor air handler breaker before connecting or disconnecting any refrigerant lines. Avoid kinking the copper tubing during routing; use a tubing bender for any directional changes. The system must be properly evacuated and leak-tested before introducing refrigerant charge.
