It is a bushing material excellent in waterproof, dustproof, heat insulation and man-hour reduction.
Since it does not adhere to the inside and outside of the partition wall, it prevents water from entering from the surroundings.
Made by EPDM
Can be used as a sealing bushing when cables or hard piping are not passed through. It can be easily penetrated by poking the sealing part.
It adheres to the inside and outside surfaces of the partition wall to prevent dust from entering inside. It also blocks the inside air to the outside.
Since the inside is hollow, it has a heat insulation effect.
*Cables and rigid piping have a bushing effect only when the cross section is circular and has a given size.
