Key Factors Influencing Water Pressure Resistance

• Core Material Design

  The water pressure resistance of breathable waterproof vent plugs is closely tied to their core material design. High-quality vent plugs often adopt porous membranes with uniform pore sizes. These membranes allow air molecules to pass through freely while blocking water droplets effectively. The structural integrity of the membrane determines its ability to withstand external water pressure, as tightly arranged pores can prevent water from penetrating even when under consistent pressure.

• Sealing Structure

  The sealing structure of the vent plug plays an important role in enhancing water pressure resistance. A well-designed interface between the vent plug and the equipment housing ensures that there is no gap for water to seep in. The integration of the vent plug with the device body, whether through threading, bonding or clamping, reinforces its ability to endure water pressure by avoiding weak points that could be compromised under stress.

• Environmental Adaptability

  Environmental adaptability also influences the actual water pressure resistance performance of vent plugs. Factors such as temperature changes and chemical exposure can affect the material properties of the membrane and the sealing structure. Vent plugs made from durable, corrosion-resistant materials maintain their water pressure resistance even in harsh conditions, while inferior materials may degrade over time and lose their protective capabilities.
