Description
PP L-shape connector A Ø 3,5–4 mm is a polypropylene tubing connector in L-form for flexible laboratory hose with an A diameter range of 3,5 to 4 mm. This right-angle fitting joins matching tubing and redirects the line through a compact 90-degree geometry, which helps keep hose runs tidy around apparatus, racks and instruments. The connector is made of polypropylene (PP) and is specified as a Verbindungsstück for Schlauch A in the stated bore window, so the hose inner diameter should fall within 3,5–4 mm for a proper mechanical fit. Pack size is 20 pieces; product data list a net weight of 0,001 kg and a gross weight of 0,001 kg per unit. These L-form hose connectors from manufacturer Witeg sit in the laboratory tubing-connector category and support straightforward push-on style coupling when dimensions align. The angled body is useful wherever a change of direction is needed without extra elbows or adapters. Select this size only when the hose matches the A Ø 3,5–4 mm range; neighbouring sizes cover larger bores in the same PP L-shape series. Origin is indicated as Italy in the specifications. Overall, the part provides a simple, material-consistent link for general laboratory fluid-line layouts that call for polypropylene L-connectors in this narrow diameter band.

Questions about Connector PP L-shape O Ø 3,5 - 4mm
What is this article?
Connector PP L-shape O Ø 3,5 - 4mm 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.
