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.

Questions about Spare O-Ring, Perbunan, DN 100 ISO-K
What is this article?
Spare O-Ring, Perbunan, DN 100 ISO-K is the article on this page. Luminix Health distributes WELCH for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
