AS200SS

The nVent HOFFMAN Hol-Sealers Hole Seal (SKU: AS200SS) is a premium 3.00-inch diameter brushed stainless steel 304 sealing solution designed to protect industrial enclosures from environmental contaminants. Engineered for durability and precision, this hole seal effectively closes pushbutton holes, conduit openings, and knockout penetrations in enclosures up to 0.31-inch (8-mm) thick, ensuring long-term resistance against dust, dirt, oil, and water infiltration. Manufactured by nVent, a global leader in electrical and thermal management solutions, the AS200SS maintains critical NEMA Type ratings (3R, 4, 4X, 12, and 13) when installed in compatible nVent HOFFMAN enclosures, making it an essential component for maintaining enclosure integrity in demanding industrial environments. Industrial-grade stainless steel 304 construction provides exceptional corrosion resistance, making the AS200SS ideal for harsh environments such as manufacturing plants, chemical processing facilities, food and beverage production, and outdoor installations. The brushed finish not only enhances aesthetic appeal but also resists fingerprints and surface scratches, ensuring a professional appearance even in high-visibility applications. With a versatile sealing range from 0.19-inch diameter to the maximum specified for this model, the Hol-Sealers line accommodates a wide variety of hole sizes and shapes, reducing the need for multiple part numbers and simplifying inventory management. Professionals in electrical, automation, and control panel industries rely on nVent HOFFMAN enclosures and accessories for their proven performance and compliance with stringent industry standards. The AS200SS hole seal is particularly valuable in applications where maintaining enclosure IP ratings and NEMA certifications is critical for safety and regulatory compliance. Typical use cases include: - **Control panel installations** in manufacturing facilities where dust and particulate contamination pose operational risks - **Outdoor electrical enclosures** requiring Type 3R or 4X protection against rain, sleet, and wind-driven debris - **Food processing and pharmaceutical environments** where washdown procedures demand high ingress protection - **Marine and coastal applications** where salt spray and humidity threaten enclosure integrity - **Hazardous location enclosures** requiring Type 4 or 4X ratings for dust and water resistance Installation is straightforward, requiring no specialized tools—simply press the seal into the hole until it snaps securely into place. The flexible design accommodates slight variations in hole diameter while maintaining a tight seal. For optimal performance, ensure the seal is compatible with the enclosure wall thickness and that the surrounding surface is clean and free of burrs. nVent provides comprehensive technical documentation and support to assist professionals in selecting the correct seal for their specific application requirements.
