Electrical Enclosure Gaskets

Electrical enclosure gasket often refers to the front panel gasket, enclosure door gasket, access panel gasket, gland plate gasket or even a connector gasket. Electrical enclosure gaskets have important considerations if the enclosure gasket needs to meet UL Gasket UL 50, UL 50E, NEMA, or IEC IP.

When planning to have gasket materials manufactured to meet specifications the following points should be considered:

  1. Protection for the enclosure gasket – the flange on the door protects the gasket from a direct pressure blast and will diffuse the force and greatly improve the chances of passing wash down testing.
  2. Door latching is the key to passing a NEMA, IP or UL gasket tests and must have the correct  means of compressing the gasket into place.
  3. The correct material composition and properties will ensure the appropriate gasket material passes tests and is the proper type required for the enclosure.
  4. The gasket rebound or resistance to taking a compression set is critical, on door gaskets that are being unseated regularly.
  5. Service Life – the longevity of an enclosure gasket depends on how the material is being used, chemicals and mechanical wear, and the amount of exposure to UV, ozone, temperature all affect longevity and service life.
