Enclosure Gasket Kits

Enclosure gasket kits are used to maintain a reliable, leak-tight seal between an enclosure and its doors, helping protect internal electrical components from dust, dirt, moisture, and other environmental contaminants. RSP Supply offers a full line of Hoffman enclosure gasket kits designed to replace worn or damaged foam-in-place or strip gaskets, as well as to upgrade existing enclosures for more demanding applications.
These gasket kits are available in silicone and EPDM materials, allowing selection based on environmental exposure, temperature range, and chemical resistance requirements. Multiple sizes are offered to accommodate wall-mounted enclosures and larger floor-standing enclosures, including options for one- and two-door configurations. Properly installed gasket kits help restore enclosure integrity and support continued compliance with NEMA Type 1 and Type 12 ratings.
Gaskets play a critical role in preserving enclosure performance, especially when enclosures are modified or experience long-term wear. In addition to excluding external contaminants, gaskets can help reduce noise and contain internal interference generated by electrical components. Selecting the correct gasket material, size, and configuration is essential for maintaining enclosure protection and long-term equipment reliability.

FAQs
Q: What are enclosure gasket kits used for?
Enclosure gasket kits are used to seal the interface between an enclosure and its doors, preventing the ingress of dust, dirt, and moisture that could damage internal components.
Q: What materials are enclosure gasket kits made from?
Common gasket materials include silicone and EPDM. Each material offers different benefits related to temperature resistance, flexibility, and environmental durability.
Q: Can gasket kits be used to replace foam-in-place gaskets?
Yes, enclosure gasket kits are designed to replace damaged or worn foam-in-place or strip gaskets and can also be used to upgrade enclosure sealing performance.
Q: What NEMA ratings are available for these gasket kits?
These gasket kits are available in NEMA Type 1 and Type 12 ratings, supporting protection against dust, dirt, and non-corrosive liquid exposure depending on the application.
Q: Why are gaskets important for enclosure protection?
Gaskets help maintain environmental sealing, protect sensitive electrical equipment, and support compliance with enclosure ratings in both indoor and outdoor applications.
Maintaining NEMA 4 Rating When Making Enclosure Penetrations
Cutouts are very common when modifying enclosures for push buttons, indication lights, conduit entries or mounting hardware. Cutting into an enclosure runs the risk of eliminating the protective nature of the NEMA rated attributes. Proper steps must be followed in order to preserve the NEMA rating of an enclosure.
Devices mounted to the enclosure must have the same NEMA rating as the enclosure. This means that if the devices are installed to the manufacturer's specifications, they will be able to maintain the NEMA rating of the enclosure.
Water tight conduit hubs must be used when running wire through a cutout in an enclosure. There are many different types of conduit hubs that are used to secure conduit to an enclosure. However, only certain conduit hubs are rated for a watertight seal. By using water tight hubs, the NEMA rating of the enclosure is maintained.
Bonded washers are necessary when mounting hardware to an enclosure. If standard mounting hardware is used, the NEMA rating of the enclosure will no longer be maintained. Bonded washers have rubber gaskets that make a watertight seal around the drilled hole. It is also important to make sure the material used for the bonded washer matches the material of the enclosure. Stainless steel enclosures require stainless steel bonded washers.
