Description
Spare O-Ring, Perbunan, DN 100 ISO-K is a replacement elastomer sealing ring for ISO-K vacuum flange connections in the DN 100 size. Made from Perbunan, it is intended for routine maintenance of laboratory and technical vacuum assemblies where the original flange seal has worn, hardened, or been damaged. The O-ring seats in the standard ISO-K groove and restores a continuous sealing face between mating flanges on pumps, chambers, adapters, and related hardware. Supplied as a single piece, it is a practical spare for workshops and laboratories that keep DN 100 ISO-K systems in service. Perbunan is widely used for vacuum and technical sealing tasks involving oils and many common process media. This spare part from manufacturer WELCH supports correct flange stack-up when installed according to equipment guidance, with even compression around the circumference. Suitable for service kits, preventive maintenance schedules, and emergency replacement stock, it helps maintain vacuum integrity on DN 100 ISO-K interfaces without changing the existing flange geometry or clamp arrangement used in the laboratory setup.
