Anti-Ammonia Rubber Washer Suits Livestock Farm Sewage Manhole Projects

A1: This elastic rubber sealing gasket fills the gap between the manhole cover and well frame. It effectively solves common problems such as metal collision noise, sewage leakage, odor diffusion, and sand dust infiltration, achieving quiet, sealed, and stable daily use of manhole covers.

A2:The high-elastic rubber material provides excellent cushioning shock absorption.It can reduce vehicle rolling noise by 15 to 25 decibels,and effectively eliminating harsh metal clanging sounds and improving urban road noise pollution.

A3: No. The gasket adopts an embossed raised anti-slip design. It can be tightly fixed between the cover and the frame without shifting or falling off during long-term vehicle rolling, maintaining stable sealing performance all the time.

A4: It fits most municipal standard wells, including drainage wells, power wells, fire protection wells, communication wells and other public utility manhole covers, widely used in urban road infrastructure projects.

A5: Yes. Thanks to its strong elasticity and flexible compression performance, the gasket can automatically compensate for casting gaps, installation errors and slight ground settlement deformation, ensuring tight sealing even for irregular well openings.
