This seal effectively prevents the ingress of dust, dirt, oil, and water, ensuring the integrity of equipment housed within enclosures. Recognized under UL 508A and CSA standards, the AS125 is suitable for a wide range of industrial applications, including those exposed to corrosive elements. Its construction features a 16-gauge galvanized steel backplate, a plated stud, and a wing nut, all designed for durability and ease of installation. The polyester powder paint finish over the galvanized front surface provides added corrosion resistance.
