Description
Connector PP Ø 7,1-12 mm / Ø 11,3-15,9 mm is a polypropylene hose connector intended for linking flexible tubing of two overlapping mid-range diameters in laboratory setups. One side is designed for hose of roughly 7,1 mm to 12 mm, and the other for hose of about 11,3 mm to 15,9 mm, allowing a smooth transition between closely related line sizes. Constructed from PP, the piece remains light and convenient for everyday fluid-handling tasks with many common laboratory media. These connecting pieces from manufacturer Witeg help assemble modular tubing paths on research benches, in teaching labs, and in technical workshops where a plastic stepped joint is preferred. Individual net weight is 0,007 kg. The connectors are offered in packs of 20 pieces, which simplifies replenishment for multi-user facilities. Classified among hose connectors, they serve temporary or more permanent fluid links without metal parts, whenever polypropylene compatibility and the stated dual hose ranges match the tubing in use for analytical or preparative applications.

Questions about Connector PP Ø 7,1-12mm/Ø 11,3-15,9mm
What is this article?
Connector PP Ø 7,1-12mm/Ø 11,3-15,9mm is the article on this page. Luminix Health distributes Witeg 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.
