Manchons longs PEHD Silent

Long HDPE Silent sleeves are essential fittings for acoustic drainage systems, designed to ensure a reliable, watertight, and durable connection between two high-density polyethylene pipes while contributing to the reduction of noise associated with wastewater flow. Thanks to their increased length, they offer a larger contact surface between the assembled components, improving the mechanical stability of the connection and enhancing the safety of the installation, particularly in networks subject to significant stress or temperature variations. Made of HDPE with a structure optimized for acoustic attenuation, these sleeves offer excellent mechanical, chemical, and thermal resistance, guaranteeing a long service life even under intensive use. Their smooth inner surface promotes a regular and quiet flow, limiting turbulence, deposits, and the risk of blockages. Compatible with HDPE Silent systems, they are easily integrated into residential, hotel, and commercial installations where acoustic comfort is a key requirement. Long HDPE Silent sleeves thus constitute a high-performance and reliable solution, combining robustness, hydraulic efficiency and noise reduction for modern and sustainable drainage networks.
