ePTFE membrane and integrated membrane are treated with special technological , have good features like water/oil repellent ,moisture- and vapor-permeable , chemically inert, non-shedding ,UV-resistant ,

temperature-resistant .Less expensive seal designs and less housing material are enabled, reducing tooling design and cost. Sinri Pressure release M12 vent Waterproof breathable automotive air vent valve has been widely used in protective automotive electronics unit or control module. M12 air vent valve can rapidly exchange of air in response to pressure changes — in other words, they allow the enclosure to breathe. By keeping the pressure differentials low, seal fatigue and housing stresses are minimized. The result — improved reliability and extended product life

Typical application:

•LED lamp

•Auto components

•Electronics & Electrical Appliances

•Telecommunication equipment

•Solar equipment

•Heavy duty equipment

•Military equipment.

•All kinds of equipments that are subject to temperature/ pressure fluctuation.
