Description
BOLA straight olives (without nut) are polypropylene (PP) laboratory hose connectors for GL threaded apparatus. This version is specified with thread GL 25, an outer olive diameter of 16,0 mm, an inner olive diameter of 10,0 mm and a length without nut of 55 mm. Each olive is equipped with an elastic sealing lip and an FKM O-ring so that the flow medium contacts only PP. The fittings are conditionally chemically resistant and rated for working temperatures up to a maximum of +110 °C. Supplied in the straight design from manufacturer Bohlender, they suit tubing connections on matching laboratory glassware and fluid-handling equipment. The pack contains 3 pieces with a net weight of 0,007 kg. Without the nut included, these olives are intended for setups that already provide a suitable GL 25 fastening. The straight geometry supports inline hose routing, while the sealing lip and O-ring promote a secure seat for everyday laboratory transfer and connection tasks.

Questions about BOLA Hose Connectors (without Nut), GL 25, Ø 16 mm POLYPROPYLENe (PP) type: stra
What is this article?
BOLA Hose Connectors (without Nut), GL 25, Ø 16 mm POLYPROPYLENe (PP) type: stra is the article on this page. Luminix Health distributes Bohlender 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.
