When laying underground oil pipelines and other pipelines at gas stations, we will open holes on the inner walls of various underground installation space containers (such as manhole operation wells and tanker bottom basins) so that the oil pipelines can extend into these containers and make necessary connections. In order to tightly seal the gaps between the pipelines and the openings on the walls of the manhole operation wells and tanker bottom basins, we have developed a series of rubber seals. The main body is made of rubber, and the fastening bolts, nuts and clamps are made of stainless steel.
