Premium Armaflex Copper Pipe Insulation from ArmaInsulation ensures superior thermal protection for HVAC systems. Designed specifically for copper piping, this 7/8″ outer diameter (OD) insulation provides a nominal 1/2″ wall thickness for optimal energy efficiency and durability. Each roll measures 6 feet long, offering extended coverage for your installation needs.
Unlike PVC-sized insulation, this product is engineered for copper piping—**not** for 3/4″ Schedule 40 PVC pipe (for PVC, consider a 1 1/8″ OD option). The seamless, slit-free design eliminates sharp edges, reducing installation risks while maintaining a tight, secure fit. Built with industry-leading materials, this insulation delivers long-lasting performance, resisting wear and maintaining thermal integrity over time. Trust ArmaInsulation for reliable, high-quality solutions tailored to professional HVAC applications.
