Oil tight hole seals are used in the electronic enclosure industry to seal conduit boxes. If at any time a conduit hole must be closed these oil tight hole seals provide the perfect solution without the need to use a new conduit box. This saves a great deal of time and money by reducing the labor of creating a new conduit box and providing the flexibility to reuse that same hole if the need should arise. These seals also help to prevent water or any other liquid from entering the enclosure.

Sierra Pacific Engineering and Products has designed these seals in many sizes, from less than a 1/2" diameter conduit hole to a 4" diameter conduit hole. Steel and stainless steel options are available to provide robust materials for many environments.
