Description
Cross connector PVDF for tubing diameters Ø 5–7 mm with cylindrical barbs provides a four-way junction for laboratory hose systems. These cross hose connectors join, branch, extend or repair flexible tubing in analytical, process and general laboratory fluid paths. Manufactured from sterilizable PVDF, the fittings combine high chemical resistance with temperature resistance up to a maximum of +160 °C, supporting a wide range of media and thermal conditions. The cylindrical barb geometry is intended for secure push-fit engagement on tubing within the 5–7 mm diameter range. Supplied in a pack of 10 pieces, the connectors are convenient for stocking multiple connection points across benches and apparatus. Net weight is 0,03 kg. This cross connector from manufacturer Bürkle belongs to an extensive portfolio of tubing connectors offered in varied forms, sizes and material grades to match diverse application demands. Typical tasks include splitting or combining lines, repairing damaged sections and building simple multi-branch manifolds where PVDF compatibility is required. The product is not supplied sterile, yet the PVDF material can be sterilized according to suitable laboratory procedures.

Questions about Four-way-connectors PVDF, for Ø 5-7 mm, cylindric.
What is this article?
Four-way-connectors PVDF, for Ø 5-7 mm, cylindric. 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.
