Beschrijving
Elbow 90° with female thread is a polypropylene (PP) laboratory fitting for changing flow direction in fluid-handling lines. The right-angle design redirects media while the internal thread enables a firm mechanical joint to matching male-threaded parts. Featuring a 1'' thread and a nominal width of 28,5 mm, this elbow addresses larger-bore laboratory and process connections used for bulk reagent transfer, wash lines and utility piping. PP construction provides a lightweight, chemically resistant body suitable for many aqueous solutions and everyday laboratory chemicals, without the weight of metal fittings. The one-piece 90° profile helps keep installations compact and organised on benches, in fume hoods or within instrument frames. Delivered as one piece with a net weight of 0,042 kg, the fitting from manufacturer Bürkle is intended for non-sterile laboratory use where a robust plastic female-thread elbow is needed. It pairs with compatible PP threaded components to build modular, serviceable fluid paths for routine laboratory workflows.

Questions about 90° bend, inner thread PP, 1'', nomin. width 28,5mm
What is this article?
90° bend, inner thread PP, 1'', nomin. width 28,5mm 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 Labmateriaal.
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.
