Rittal SZ bucim de compensação de pressão M12 x 1,5 aço inoxidável 1.4305 IP68 (4000300)

Temperature fluctuations inside sealed enclosures cause pressure differentials that stress seals, promote condensation, and can lead to premature failure of sensitive electronics. The Rittal SZ pressure compensation plug equalizes internal and external pressure while blocking moisture and contaminants, ensuring long-term reliability of your control cabinets and industrial enclosures.

Who is it for

This plug is essential for panel builders, system integrators, and maintenance engineers who need to protect outdoor or washdown-rated enclosures from pressure-related damage. It is ideal for applications in food processing, chemical plants, marine environments, and any location with wide temperature swings or high humidity.
