Overview

The nVent Hol-Sealers Hole Seal, SKU AS150, provides essential protection for industrial enclosures. Manufactured by nVent, this 2.50-inch diameter seal is constructed from durable mild steel with a gray finish. It effectively seals unwanted openings like pushbutton holes, conduit knockouts, and other unused openings, preventing the ingress of dust, dirt, oil, and water. This helps maintain enclosure integrity and environmental ratings, including Type 3R, 4, 12, and 13 when used with compatible nVent HOFFMAN enclosures. The Hol-Sealers Hole Seal accommodates various hole sizes and can be installed on enclosure walls up to 0.31 inches (8 mm) thick. Applications include manufacturing plants, food and beverage facilities, water treatment, and oil and gas operations. Installation is typically a simple press-fit or gasketed seal. The mild steel construction offers good durability, and the gray finish provides a clean aesthetic. Choose nVent Hol-Sealers for reliable sealing performance from a trusted manufacturer.
