Overview

The nVent HOFFMAN Gasket Replacement Kit (SKU: GSKTKITE375) is a high-performance EPDM gasket solution designed to restore or upgrade the sealing integrity of Hoffman enclosure doors, covers, and gland plates. Engineered for Types 4, 4X, and 12 enclosures, this kit provides a reliable barrier against water, dust, and environmental contaminants in industrial and commercial applications. Whether replacing worn foam-in-place or strip gaskets, or upgrading to a more durable sealing solution, this EPDM gasket kit delivers consistent performance in harsh operating conditions. Manufactured by nVent, a global leader in electrical and thermal management solutions, the GSKTKITE375 is built to meet rigorous industry standards, including UL 508A Component Recognition (File No. E61997) and cUL Component Recognition per CSA C22.2 No. 94. The EPDM material offers excellent resistance to ozone, UV exposure, and extreme temperatures, making it ideal for outdoor enclosures, control panels, and electrical housings exposed to moisture or corrosive environments. The .38-inch thickness and 1.00-inch width provide a secure seal for large enclosures, ensuring compliance with NEMA Type 4, 4X, and 12 requirements for ingress protection. Each kit includes a 20-foot roll of strip gasket, pre-cut adhesive backing, and installation instructions for field-replaceable applications. The gasket is positioned inside the enclosure door, creating a tight seal between the housing and door to prevent contaminants from compromising sensitive equipment. Unlike traditional foam gaskets, which degrade over time, the EPDM material maintains its flexibility and sealing properties across a wide temperature range, reducing maintenance costs and downtime. Professionals in industries such as manufacturing, utilities, telecommunications, and automation rely on nVent HOFFMAN gasket kits to maintain enclosure integrity in critical applications. The GSKTKITE375 is particularly suited for wall-mount and free-standing enclosures where robust sealing is essential, such as in food processing facilities, chemical plants, or marine environments. By choosing this replacement kit, users can extend the lifespan of their enclosures while ensuring compliance with safety and environmental standards. nVent’s reputation for innovation and durability makes the GSKTKITE375 a trusted choice for engineers and technicians seeking a cost-effective, high-quality gasket solution. Whether upgrading legacy systems or installing new enclosures, this kit provides a seamless, field-installable solution that meets the demands of modern industrial applications.
