Mueller HVAC Control 41020350B6 35 Ft

Copper Refrigerant Line Set 35 Ft

The Mueller HVAC Control 41020350B6 provides a 35 foot copper roll for refrigerant piping. It includes a 1/4 inch liquid line and a 5/8 inch suction line with half inch insulation on the suction side. This set suits installers connecting compatible split system components.

Replaces Worn Or Undersized Line Sets

Technicians choose this roll when existing copper lines show leaks, kinks or inadequate insulation. The 35 foot length covers standard runs between indoor and outdoor units without joints. Upgrading is worth it when pressure tests fail or when insulation has degraded and causes condensation or capacity loss.

Consistent Thermal Performance Over Full Length

The half inch insulation on the suction line maintains stable refrigerant temperature during extended cooling cycles. Copper construction resists vibration fatigue and corrosion through repeated seasonal changes. The continuous roll eliminates braze joints that can become leak paths under long term pressure cycling.
