The pressure difference generated inside and outside of the gas discharge lamp can easily damage the lamp, which is particularly important for lamps that must work through changing temperature environment; therefore, designers will introduce microvent plugs to balance atmospheric pressure as well. Microvent plugs resist automotive fluid and chemical erosion, such as urea solutions, car washes and lubricants that can damage, degrade or cause premature failure of electronic components.

Microvent supplies new generation ventilation technology with broad-based application type configurations to respond to diverse automotive electronic applications. These vents come in Snap-Fit, Weldable and Adhesive installation methods with a range of performance levels and sizes for targeted applications. Microvent electromagnetic compatible waterproof vent plugs, high up in protection level IP67, IP68 and even specific to be IP69 stand out while complying with implication of GB4208-2008/IEC60529:2001 standard for environmental protection from the view ownership as applied using broadly on electrical industry.
