Description
Elbow 90° with female thread is a polypropylene (PP) laboratory fitting for redirecting fluid lines at a right angle in tubing and piping setups. The connector features internal threading at 1/2'' with a nominal width (NW) of 17,5 mm, enabling compact 90° changes of direction in process, sampling or general laboratory fluid systems. Made from PP, the elbow offers a lightweight, chemically resistant option for aqueous and many common laboratory media where metal fittings are unnecessary. Supplied as a single piece from manufacturer Bürkle, it has a net weight of 0,017 kg and is intended for non-sterile technical use. Typical applications include bench-scale fluid routing, apparatus assembly and modular tubing networks that require a reliable female-thread 90° bend without adding significant mass or bulk to the installation.

Questions about 90° bend, inner thread PP, 1/2'', nom. width 17,5mm
What is this article?
90° bend, inner thread PP, 1/2'', nom. width 17,5mm 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 Matériel de laboratoire.
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.
