Description
Spare O-ring in Perbunan for DN 63 ISO-K flange connections is a replacement sealing element for laboratory vacuum and process equipment. The ring restores the interface seal on ISO-K DN 63 joints when the original elastomer is worn, compressed, or contaminated. Perbunan provides the elastomeric compliance needed for flange mating under typical laboratory vacuum service. This single-piece spare from manufacturer WELCH supports maintenance of pumps, chambers, and manifold sections that use the DN 63 ISO-K standard. Fitting a fresh O-ring helps re-establish leak-tight geometry without replacing the entire flange assembly. The component is intended as a direct spare part within laboratory equipment accessory ranges. Use it during scheduled service or after seal inspection when surface damage or permanent set is observed. Clear DN 63 ISO-K designation simplifies matching to existing hardware. Pack size is one piece, suitable for targeted repair stock rather than bulk consumable use. It belongs with other vacuum-system spare parts kept for continuous instrument availability.
