Mueller Industries 61230500c Refrigerant Line Set 50 Ft

Product Description

The MUELLER INDUSTRIES 61230500c is a pre-insulated refrigerant line set designed for residential and light commercial HVAC installations. It includes a 3/8-inch liquid line and a 3/4-inch suction line, both factory-assembled and ready for field connection. The suction line is wrapped in Duraguard UV-resistant coated elastomeric insulation at 3/4-inch wall thickness, built to hold up against prolonged solar exposure and outdoor weathering. The line set ships in a 50-foot length and is rated to 700 psi. It is UL Recognized and manufactured in compliance with ASTM B1003. Licensed HVAC technicians performing refrigerant line installations are the primary end users.

This line set is suited for split-system and mini-split air conditioning and heat pump installations where pre-insulated copper line sets are required. The Duraguard polymeric jacket makes it well-suited for exposed exterior runs on rooftops, building sidewalls, or other applications subject to UV and weather degradation. The 50-foot factory length covers the majority of standard residential linesets without field splicing. The line set arrives coiled and can be unrolled and routed through standard penetrations during system installation.
