Description
KF connector DN 16 KF - 1/4 PP is a laboratory vacuum fitting that joins a DN 16 KF (NW) flange interface to a 1/4 connection in polypropylene (PP). The component is intended for vacuum and laboratory gas-line assemblies where a compact KF-side coupling must mate with a smaller 1/4 port. Polypropylene construction provides a lightweight, chemically resistant body suitable for many general laboratory vacuum setups. The DN 16 KF geometry follows the familiar small-flange format used across bench-top pumps, manifolds and apparatus, while the 1/4 side supports tubing or threaded adapters common in lab plumbing. Offered by manufacturer WELCH as a single piece, this connector belongs to standard laboratory materials for building or maintaining KF-based vacuum lines. It is useful wherever a DN 16 KF to 1/4 transition in PP is required without metal hardware, helping keep assemblies simple and corrosion-resistant in teaching, research and routine analytical environments.

Questions about KF connector DN 16 KF - 1/4 PP
What is this article?
KF connector DN 16 KF - 1/4 PP 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.
