Description
Thread adapter G3/4'' outer – 20x4 (Kautex) outer, blue belongs to the LaboPlast® range and enables secure connection of StopCock outlet cocks, ball valves and other laboratory accessories to common commercial containers. One side carries a standard G 3/4'' external thread while the opposite side matches the 20x4 outer thread used on Kautex-style vessels, providing a direct, leak-resistant interface without additional fittings. The distinctive blue colour aids quick visual identification among other adapters on the bench. Produced by manufacturer Bürkle, the adapter is supplied as a single piece and weighs only 0,008 kg, making it easy to keep multiple variants on hand. All LaboPlast® thread adapters share the uniform G 3/4'' external thread standard, so the same valves and accessories can be moved freely between different container types. Ideal for sampling, dispensing and temporary process set-ups where rapid, reliable container connections are essential. The robust construction supports repeated assembly and disassembly in daily laboratory workflows.

Questions about Thread ad. G 3/4'' outer- 20x4 (Kautex) outer, blue
What is this article?
Thread ad. G 3/4'' outer- 20x4 (Kautex) outer, blue 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.
