Our gasket for the Ø500 manhole cover is an O-ring with a diameter of 20 mm and a length of 1.8 m. It is designed to provide a secure and tight seal between the manhole cover and the frame, preventing any leaks or debris from entering the silo. The gasket is made of high-quality materials to ensure durability and resistance to wear and tear, as well as resistance to corrosion and weather influences.
