Oil tight hole seals are used to cover conduit or push button holes as well as seal any openings to prevent dirt, water, dust, and oil from entering an enclosure. With this type of seal, users are able to cover enclosures without needing to create a new conduit box as well as allow them to reuse the hole should the need arise. Sierra Pacific Engineering and Products oil tight hole seals come in various sizes, able to cover holes with diameters ranging from 3/16” to 4 5/8”. The seals come in two types: stainless steel with a brushed /grained finish and steel with a gray painted finish that matches ANSI 61 industrial enclosure cabinets. These robust materials ensure the durability of the seals in different environments. Each set includes a cap, an oil-resistant gasket, a backplate, and a wing nut. All Sierra Pacific Engineering and Products Oil Tight Hole Seals are UL 508A Recognized components.
