Description
PTFE olives, straight, are laboratory hose connectors designed for secure fluid and gas line coupling on GL-threaded vessels and fittings. These straight olives feature a GL 18 thread interface with an outer diameter of 10,5 mm and an inner diameter of 7,5 mm, supporting reliable tubing attachment in chemical, analytical, and general laboratory workflows. Manufactured from PTFE, they offer broad chemical resistance and low surface energy for clean, low-adhesion fluid paths when connecting flexible tubing to bottles, flasks, or process lines. The straight geometry suits in-line or axial hose routing where a compact, non-angled connector is preferred. Supplied as a pack of 10 pc(s) from manufacturer DWK Life Sciences, the set is practical for equipping multiple setups or maintaining spare connectors in the lab. Typical uses include media transfer, inert-gas blanketing lines, sampling loops, and accessory connections on GL 18 bottle necks and adapters within seals, hose connectors, and laboratory container systems. Dimensions and thread size should be matched to the corresponding tubing bore and GL 18 hardware for a secure fit.
This article belongs on Bottle accessories (pouring rings, dispensers, caps), in Bottles & containers.

Questions about Olives, PTFE, straight, GL 18, outer Ø 10.5 mm, inner Ø 7.5 mm, 10 unit(s)
What is this article?
Olives, PTFE, straight, GL 18, outer Ø 10.5 mm, inner Ø 7.5 mm, 10 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Bottle accessories (pouring rings, dispensers, caps), inside Bottles & containers, in Labware.
Bottle accessories are the pieces on the neck: a pouring ring, a dispenser seat, a cap liner, a tamper ring. They decide how the bottle delivers and whether the closure still matches after the original cap is gone.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
