Airflow ranges span different model rows, not the adjustment range of one vent. IP ratings are catalogue statements; verify the selected model’s test conditions and the assembled enclosure. IP68 immersion depth and duration are not supplied in these listings.
Bring us your enclosure requirements.
Start with the material, mounting interface and airflow you need.
Specify the vent.
Validate the enclosure.
Thread size alone does not determine a suitable vent. Send the mounting details and operating conditions together.
Prepare your specificationMatch the mounting interface
Thread form, pitch, engagement and clearance; or the snap-in opening, panel thickness and retention requirements.
State airflow with its test pressure
Compare values at the same pressure differential. These catalogue figures use 70 mbar; they do not define enclosure equalization time.
Confirm material and exposure
Share temperature, washdown, chemicals and outdoor exposure. Request the required metal grade, membrane and seal specification.
Review a sample assembly
Confirm installation torque, sealing surfaces and the applicable ingress test before approving the enclosure design.
Questions before
you specify.
Is a vent plug the same as a cable gland?
No. A cable gland provides a cable entry and sealing interface. A vent plug provides a ventilation path through a separate enclosure opening; it is not a cable entry.
Does every series have the same IP rating?
No. The current PA66 threaded and snap-on listings state IP67. The metal listings state IP68. The rating of a component does not automatically establish the rating of the completed enclosure. Ask for model-specific test conditions.
Can I select a vent from enclosure volume alone?
Not reliably. Selection also needs the pressure-change requirement, temperature profile, leakage paths, available mounting position and the vent’s airflow characteristics. Provide these details for a technical review.
Why do some thread sizes appear more than once?
The same printed thread can have different overall lengths, thread lengths or airflow values. For example, the plastic M12 × 1.5-10 entries differ. Include the complete dimension row when ordering.
What information is needed for a quotation?
Send the series or model, material, thread or snap-fit dimensions, required airflow and pressure, application conditions, quantity and delivery destination. Include a drawing where available.
