For protecting the cables that pass through the metal parts we use a rubber grommet. We are using this for protecting the metal parts it is designed in such a way that has rubber flexibility, tear resistance, and weather resistance. The rubber grommet manufactured by the Qingdao Guanshan Industry Co., Ltd has additional features to improve their quality. They have imported DOW EPDM for long time exposure to the sun and NBR materials which are suitable for the oil environment.
Instead of providing only the standard shape of it, they have custom machining service to provide them the special sizes based on the customer needs. The various materials available in this process of manufacturing are EPDM, NR, NBR, PVC +NBR, FKM, silicone, Neoprene. The hardness of the product is between 40 Shore A and 85 Shore A. And the tensile strength is between 6 MPA and 24 MPA. The available colors of this grommet are black, red, green, blue, and yellow. Hence these kinds of grommet manufactured by this company have more quality and strength when compared to other company. They are highly safe and secure to use with the cables that are passing through the metal parts.
