Description
Hose olive, plastic with silicone seal, straight, GL18 is a laboratory hose coupling component for secure tubing connections on GL 18 threaded glassware and apparatus. The straight plastic olive is made of PTFE and fitted with a silicone gasket, giving a chemically resistant body and a flexible sealing interface for leak-tight hose attachment. GL 18 threading matches common laboratory bottles, flasks and reaction vessels used in research, synthesis and quality-control work. At a net weight of only 0,002 kg the fitting remains light while supporting repeated assembly and disassembly in fluid-transfer setups. Straight geometry allows simple inline hose routing without angular offsets, which is practical for compact bench layouts and manifold builds. This hose olive from manufacturer Witeg is intended for Schlauchkupplungen and general laboratory media handling where inert materials and reliable sealing are required. Supplied as a single piece, it serves as a ready replacement or as a building block when configuring new tubing lines on GL 18 ports. The combination of PTFE construction and silicone sealing supports everyday chemical and analytical workflows that demand durable, chemically compatible hose olives.

Questions about Plastic hose sonnection straight GL 18
What is this article?
Plastic hose sonnection straight GL 18 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Silicone tubing, inside Tubing, hoses & fittings, in Labware.
Silicone tubing stays flexible across a wide temperature range and survives repeated autoclaving, which is why peristaltic pumps and media lines use it. It is not the choice for strong solvents, which migrate into the wall.
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.
