Vent plug applications

Tips: Functions of the Vent Plug

Dustproof: The vent plug prevents dust and other solid particles from entering the system, keeping internal components clean and protected.
Hydrophobic: It repels water and moisture, stopping liquids from penetrating while still allowing air to pass through.
Breathable: The breathable vent plug allows air and gases to flow in and out, balancing internal pressure and preventing vacuum or overpressure conditions.
Heat Dissipation: By enabling airflow, it helps dissipate heat from enclosed spaces, preventing overheating and maintaining optimal operating temperatures.

Existing reviews of Waterproof Aluminum Alloy Breather Vent Plug, IP67

CAD files and technical drawings

Could you provide the CAD files and technical drawings for parts ATO-MS-LC-6061 M5 and M6? Are there precise specifications for the threaded holes to ensure reliable O-ring seals?

ATO Responded

Sorry, we do not have CAD drawings, only dimensional diagrams from the webpage. The reliability of O-ring seals depends on the accuracy of your groove dimensions and surface finish.

5mm threaded vent plug

Are 5mm threaded vent plugs available on the market? Vpht or BX-30 models are both acceptable. What is the price for 3?
