HOW TO SELECT THE IDEAL ENCLOSURE GASKET

From Hoffman

Gaskets are mechanical devices used to provide a leak-tight seal between two slightly irregular mating surfaces, such as an enclosure and its doors and accessories. In many indoor and outdoor applications, a properly mounted, well-performing gasket is critical to the protection of sensitive electrical and electronic equipment inside the enclosure. While gaskets are primarily used to exclude the external environment from entering an enclosure-such as dust, dirt, water, and Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI)-they can also be used to contain noise or other forms of interference generated from internal components. To ensure proper performance and long service life, specifiers should select a gasket that is specifically designed and rated for an application's environment.
