Description
Straight connector with conical nozzle in polypropylene (PP) for hose inner diameters in the 7–10 mm range provides a simple two-way link for laboratory and process tubing. The conical barb geometry helps seat flexible hoses securely so lines can be extended, joined or repaired without complex fittings. Made from polypropylene, the connector suits everyday aqueous media handling where a lightweight, chemically resistant plastic is preferred, and the design is described as sterilizable for workflows that require thermal or other routine sterilization steps. With two connection ends, it supports straightforward in-line coupling rather than branching. A net weight of 0,03 kg keeps the part unobtrusive on bench setups and portable assemblies. This hose connector from manufacturer Bürkle belongs to a broad portfolio of tubing connectors offered in varied forms, sizes and materials to match diverse laboratory requirements. Supplied in packs of 10 pieces, it is practical for stocking common hose sizes used in sampling, transfer and general fluid routing tasks.

Questions about Connector straight, conical nozzle, PP, Ø 7-10mm
What is this article?
Connector straight, conical nozzle, PP, Ø 7-10mm is the article on this page. Luminix Health distributes Bürkle 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.
