Overview

The nVent Hol-Sealers Hole Seal, SKU AS075SS, provides essential protection for industrial enclosures. Constructed from 300 series stainless steel with a brushed finish, this seal is designed to cover 3/4-inch conduit holes or M25 openings, fitting holes from 1.06 inches (27mm) up to this maximum. It effectively seals unused pushbutton, conduit, and knockout openings against dust, dirt, oil, and water, maintaining enclosure integrity. The seal accommodates enclosure wall thicknesses up to 0.31 inches (8mm). When installed in an nVent HOFFMAN enclosure, this stainless steel version helps maintain NEMA and IEC Type ratings, including Type 3R, 4, 4X, 12, and 13, and IP66. Its oil-resistant gasket ensures reliable sealing across a wide temperature range (-55°C to 180°C). Key benefits include robust environmental sealing, maintenance of enclosure ratings, versatile hole coverage, and durable stainless steel construction for longevity in demanding industrial applications. Industries such as manufacturing, oil and gas, and water treatment rely on this solution to prevent costly downtime and equipment damage.
