Benefits of 1/4" x 1/2" Refrigeration Copper Pipe

Excellent Heat Preservation Insulation

The high-density closed-cell insulation structure has low thermal conductivity and stable temperature performance. It helps protect refrigerant lines from outside temperature changes.

Moisture Condensation Control

The insulation material functions as both a thermal insulation layer and a moisture-proof layer, helping reduce pipe sweating and moisture-related damage around the line set.

Corrosion-Resistant and Long-Lasting Material

The insulation material is designed to resist corrosion, acid and alkali exposure, helping extend service life in HVAC and refrigeration installation environments.

Flame-Retardant Insulation Options

Flame-retardant insulation options are available for HVACR projects that require higher fire safety performance and export market compliance.
