Identifying the Proper Electrical Enclosure Gaskets And Seals

The electrical enclosure gaskets & seals protect electronic components inside electrical enclosures from external elements, like weather conditions, and keep electrical hazards out of the enclosure. The right gasket will ensure the perfect seal for outdoor and indoor enclosures that can last the item's lifetime.


ENSURING THE PROPER PERFORMANCE OF AN ELECTRICAL ENCLOSURE GASKET


The most significant element of a gasket for an electrical enclosure is making sure that the gasket complies with particular requirements for the application. Most electrical enclosures have to meet certain kinds and ratings, such as NEMA, UL, and IP (Ingress Protection).


To pass these inspections, it is necessary to think about the following issues:


  • Temperature - What temperature range is needed?
  • Location Will the application be outdoor or indoor?
  • UV Resistance - Will the material be exposed directly?
  • Fire Resistance - Does the material need a specific flame rating?
  • Outgassing of materials - Will the outgassing be harmful to electronic components?
  • Gap Spacing - What is the gap size to be filled with the gasket?
  • The Gasket's Function: What type of protection must the gasket offer? (air, liquid, vibration?)


MATERIAL SELECTION FOR CUSTOM ELECTRICAL ENCLOSURE GASKETS


If you can answer the above questions, the selection of materials procedure will become easier. There are many options for achieving the ideal seal for enclosures. In particular, about gasket performance, It is easy for manufacturers to recommend a product that exceeds the specifications and results in higher expenses. Choosing the most cost-effective solution to every situation is essential while still delivering optimal performance.


Common materials used to make the creation of custom-designed electrical enclosure seals are the following:

  • Closed Cell Sponge Rubber (Neoprene, EPDM, Nitrile, PVC, SBR)
  • Cellular Urethane
  • Polyethylene
  • PORON(r) Polyurethane
  • BISCO(r) Silicone


All materials are in a bonded adhesive with an adhesive that is pressure sensitive in the event of need.


WHAT ARE THE RISKS ASSOCIATED WITH AN UNDERPERFORMING SEAL?


  • The cost of gaskets for replacement and the ongoing maintenance that comes with gasket replacement
  • The enclosure could be removed from the rating.
  • Cost of electronic components that are damaged inside an enclosure
  • The most common cause of systemic errors is damaged electrical components
  • Quality concerns from enclosure makers
