O-ring, 28 x 3 mm – Viton, Part# 79509 – vacstellar

This O-ring is made from Viton (FKM). Viton is a special rubber famous for its resistance. It handles oils, fuels, and many chemicals much better than standard rubber. This makes it last longer in tough conditions.

This is a truly universal part. It fits a wide range of vacuum pump brands you know and trust. This includes models from Alcatel-Adixen, Leybold, Busch, and others. Whether you’re maintaining a lab pump or an industrial system, this O-ring is likely compatible.

Keeping a spare on hand is smart. Replacing a worn seal during regular maintenance prevents downtime and costly repairs. Ensure your equipment stays sealed and efficient.
