Description
Nalgene™ Valved Barbed Quick Disconnects are laboratory fluid-handling fittings intended to help maintain the integrity of liquids during transfer. These barbed, valved quick-disconnect connectors combine a secure barb interface with an integrated valve so lines can be separated while limiting uncontrolled flow. The inner diameter is 0,25 in (6,4 mm) and the overall length is 83,3 mm (3,28 in), matching use with 1/4 in (6,4 mm) I.D. tubing. Flexible construction supports practical routing and handling in bench and process setups. Maximum operating pressure is specified at 2 psig, aligning the parts with low-pressure laboratory transfer tasks rather than high-pressure service. Each unit size is supplied as a case of 12 pieces, organised as 2 per pack, which suits stocking common tubing sizes across multiple workstations. These Nalgene™ connectors from manufacturer Thermo Scientific - Laboratory Plastics are positioned for routine liquid-transfer workflows where repeatable connect and disconnect steps are required. Clear dimensional matching to 6,4 mm I.D. tubing simplifies selection, while the valved barbed format supports controlled handling of process or sample liquids in research and quality environments.

Questions about Nalgene™ Valved Barbed Quick Disconnects
What is this article?
Nalgene™ Valved Barbed Quick Disconnects is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics 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.
