Description
Spare O-ring, Viton, DN 16 KF is a replacement sealing ring for KF vacuum flange connections on laboratory equipment. Produced from Viton elastomer, it is dimensioned for the DN 16 KF (Klein Flange) interface widely used on smaller vacuum lines, pumps, fittings and accessories. Delivered as a single piece, the O-ring serves as a ready spare when seals wear, compress set or need scheduled exchange during maintenance. The DN 16 KF format aligns with standard Klein Flange geometry, supporting a proper fit on matching components and helping restore joint integrity after service. In laboratory vacuum set-ups, effective O-ring sealing at KF ports is important for stable connections during sample work, system assembly and process support. Stocking a Viton DN 16 KF spare helps limit downtime when a seal must be changed promptly. This replacement part from manufacturer WELCH is intended for users maintaining KF-connected laboratory apparatus who require a clear DN 16 KF Viton option without modifying existing flange hardware.

Questions about Spare O-Ring, Viton, DN 16 KF
What is this article?
Spare O-Ring, Viton, DN 16 KF 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.
