Description
Straight polypropylene (PP) connector for hose diameters Ø 3–5,5 mm provides a simple through-connection for flexible laboratory tubing. This fitting is intended for hoses with outer diameters in the 3 to 5,5 mm range, enabling in-line joints in fluid transfer, instrument feed lines, and general laboratory tubing assemblies. Polypropylene construction makes the connector a practical choice for many routine aqueous and chemical handling applications found in research and quality-control laboratories. The straight geometry keeps flow paths direct and is useful wherever a compact, non-angled link between two hose ends is preferred. Supplied in a pack of 20 pieces, the product gives sufficient quantity for building multiple set-ups or holding spares beside the bench. These connectors from manufacturer Witeg form part of a hose-connector range used across analytical, biotech, and teaching laboratories. Recorded net weight is 0,001 kg and gross weight is 0,001 kg, underscoring the lightweight nature of the PP design. Specify the 3–5,5 mm size when matching tubing outer diameter to the connector range, and select the 20-piece pack to streamline purchasing for ongoing laboratory maintenance and assembly work.

Questions about Connector PP straight Ø 3-5,5mm
What is this article?
Connector PP straight Ø 3-5,5mm 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.
