Description
SVS hose coupling GL18 is a straight laboratory hose coupling fitted with a cap, an 11 mm outer-diameter olive, a threaded tube and a silicone gasket, manufactured in polypropylene (PP). The GL18 thread interface supports secure attachment in laboratory tubing and vessel setups that use standard GL screw connections, while the olive geometry enables reliable hose push-on connection. The integrated silicone gasket contributes to a dependable seal at the joint, and the straight design keeps flow paths simple for general fluid transfer. Supplied as one piece with a net weight of 0,025 kg and a gross weight of 0,025 kg, the coupling is a complete ready-to-fit unit for bench and instrument work. This SVS hose coupling comes from manufacturer Witeg and is produced in Germany (Baden-Württemberg). It suits laboratories that standardise on GL18 connections and require a PP body with silicone sealing for everyday aqueous and mild-chemical hose lines. The combination of cap, olive, threaded tube and gasket in one assembly simplifies installation and spare-part logistics for fluid-handling stations.

Questions about SVS-tubing connection GL 18
What is this article?
SVS-tubing connection GL 18 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.
