Description
PVC tubing 19 x 4 mm is a robust laboratory hose in polyvinyl chloride (PVC) featuring an inner diameter of 19 mm and a wall thickness of 4 mm. The thicker wall provides added mechanical stability for larger-bore transfer lines while retaining the flexibility expected of PVC tubing in bench and utility installations. Offered in a 25 m length, the product is suited to fluid routing, media supply and general laboratory plumbing where a 19 mm internal diameter supports higher volumetric flow than narrower grades. Smooth PVC construction facilitates cutting, fitting and connection to standard laboratory couplings when compatibility with the process medium has been verified. This tubing from manufacturer Witeg is intended for everyday laboratory infrastructure alongside other polymer hose options such as PE, PP, silicone or PTFE lines selected by application. Dimensionally defined metric sizing simplifies replacement and system design in research, quality-control and teaching laboratories. Confirm chemical resistance of PVC against the intended solvents or reagents before permanent installation, and follow local laboratory safety and waste-handling procedures for all transferred media.

Questions about PVC hose 19x4mm
What is this article?
PVC hose 19x4mm is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in PVC, PTFE & other tubing, inside Tubing, hoses & fittings, in Labware.
PVC is the flexible everyday tube for water and mild aqueous liquids. PTFE is the stiff, almost inert tube for solvents. Other polymers sit between them. The bore, the wall and the chemical resistance are the specification, and the tube is cut to length.
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.
