Description
Straight polypropylene (PP) connector for hose diameters Ø 4,5–8,2 mm is a laboratory tubing fitting for reliable in-line fluid connections. It is designed for flexible hoses with outer diameters from 4,5 to 8,2 mm, supporting transfer lines, instrument links, and general bench tubing layouts that need a straight joint. Polypropylene offers a lightweight body suited to many routine laboratory fluid-handling tasks in research, quality control, and teaching environments. The straight form factor keeps the connection compact and is preferred when an angled piece is unnecessary. The product is supplied in a pack of 20 pieces, providing a practical multi-unit quantity for assembly work, replacements, and spare stock. From manufacturer Witeg, these PP connectors belong to the hose-connector category and help standardise tubing interfaces across modular laboratory set-ups. Net weight is 0,002 kg and gross weight is 0,002 kg according to the recorded unit data. Match the 4,5–8,2 mm range to your hose outer diameter when specifying the fitting, and use the 20-piece pack to cover several installations or maintenance cycles without frequent reordering.

Questions about Connector PP straight Ø 4,5-8,2mm
What is this article?
Connector PP straight Ø 4,5-8,2mm 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.
