Mueller Streamline LS-583850P-08 Line Set 50 Ft

Product Description

The MUELLER STREAMLINE LS-583850P-08 is a pre-insulated copper refrigeration line set designed for residential and light commercial HVAC installations. The set consists of two copper lines -- a 5/8-inch OD suction line and a 3/8-inch OD liquid line -- run together at 50 feet in length. Factory-applied 1/2-inch foam insulation covers the suction line to reduce condensation and limit thermal loss across longer routing distances. Licensed HVAC technicians install this line set to connect outdoor condensing units to indoor evaporator coils.

This line set is suited for residential split-system installations where the distance between the indoor and outdoor units requires a full 50-foot run. The 5/8 x 3/8 OD sizing matches common residential equipment configurations in the 2-ton to 3-ton range. The extended run length and enhanced insulation thickness make this set a practical choice for installations with complex routing through walls, attics, or crawl spaces where additional thermal protection is needed.

Key Features

• 50-foot factory-paired run -- no field splicing required for standard extended-reach installations
• 5/8-inch OD suction line and 3/8-inch OD liquid line for common residential split-system sizing
• 1/2-inch factory-applied foam insulation on the suction line to control condensation and reduce heat gain
• Copper construction for reliable refrigerant transfer and compatibility with standard flare and sweat fittings
• Pre-paired configuration simplifies staging and reduces installation time on the job

Compatibility

Designed as an OEM-style replacement or new-installation line set for residential split-system air conditioners and heat pumps requiring a 5/8 x 3/8 OD line set configuration at 50 feet.

Installation Notes

Installation should be performed by an EPA 608-certified HVAC technician. Disconnect and lock out power to both the indoor and outdoor units before making any refrigerant-side connections. After brazing or flaring connections, pressure-test and evacuate the line set to the equipment manufacturer's specified micron level before introducing refrigerant. Secure the line set at regular intervals per local mechanical code to prevent vibration-induced wear on the insulation and copper tubing.
