Description
Check valve with conical nozzle for hose diameters of 6–8 mm is a compact non-return fitting for reliable one-way flow control in laboratory and industrial tubing systems. It carries an embossed and black printed direction arrow so installation orientation is immediately clear and reverse flow can be avoided in fluid lines. Conical hose barbs accept flexible tubing securely, while the internal polypropylene (PP) valve ball provides the sealing element for directional control. Maximum pressure loading is 4 bar, and the operating temperature range is +0 to +40 °C. Supplied as one piece with a net weight of 0,006 kg, this valve from manufacturer Bürkle belongs to a broad portfolio of hose connectors used to lengthen, join, branch, merge or repair tubing runs. Application areas are diverse, so the range covers many forms, sizes and material properties to match practical fluid-handling needs. The printed check valve is suited to everyday laboratory setups that require dependable non-return performance and straightforward hose attachment without complex fittings or adapters.

Questions about Non-return valve, conical nozzle, Ø6-8mm, printed
What is this article?
Non-return valve, conical nozzle, Ø6-8mm, printed is the article on this page. Luminix Health distributes Bürkle for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
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.
