Products Description

POLYGON PERT Tubing is engineered for durability and efficiency in both residential and commercial applications. The PE-RT I Pipe offers excellent creep resistance, flexibility, and ease of installation, while the PE-RT II Pipe utilizes superior raw materials for enhanced pressure and temperature resistance (up to 95°C long-term). The Oxygen Barrier Pipe variants (3-layer and 5-layer) incorporate an ethylene vinyl alcohol (EVOH) layer to block oxygen diffusion, reducing microbial growth and metal corrosion. The Capillary Pipe features a slim design (e.g., 7.2x1.1 mm) for uniform thermal distribution in radiant systems, and the Two-Layer Pipe adds an outer protective layer for shading against light-induced microbial growth. All pipes are produced using German KraussMaffei and Swiss Maillefer equipment, ensuring precision and consistency.
