Description
Connector PP Ø 3,7-8,2 mm / Ø 7-11,8 mm is a polypropylene tubing connector for joining laboratory hoses across two diameter ranges. One side accepts tubing from 3,7 mm to 8,2 mm outer diameter, while the other side fits hoses from 7 mm to 11,8 mm, enabling stepped or transitional connections in fluid-handling setups. Manufactured in PP, the fitting is suited to general laboratory transfer lines where a lightweight, chemically resistant plastic joint is preferred.
This article is part of Hose connectors, adapters & fittings, in Tubing, hoses & fittings.
These connecting pieces support flexible tubing runs in sample preparation, reagent supply, and apparatus assembly without metal hardware. Clear diameter markings in the product designation simplify selection against existing hose stock. The connectors come from manufacturer Witeg and are packed as 20 pc(s), convenient for workshops, teaching labs, and multi-station benches that frequently reconfigure tubing. Net weight is 0,01 kg per unit context, keeping storage compact. Use for non-pressurized or low-demand laboratory hose links within the stated diameter windows, matching PP compatibility to the media in use.

Questions about Connector PP Ø 3,7-8,2mm/Ø 7-11,8mm
What is this article?
Connector PP Ø 3,7-8,2mm/Ø 7-11,8mm 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.
