Description
Elbow 90° with female thread is a polypropylene (PP) pipe fitting designed for directional changes in laboratory and process fluid lines. The 90° geometry redirects flow cleanly while the internal thread provides a secure, screw-type connection to matching male-threaded components. With a 3/4'' thread size and a nominal width of 23 mm, this elbow suits medium-bore tubing and rigid piping commonly used in sample transfer, reagent distribution and general laboratory utilities. Manufactured from PP, the fitting offers good chemical resistance to many aqueous media and routine laboratory chemicals, together with low weight and straightforward handling. The compact one-piece form supports neat routing in tight instrument layouts and bench-top assemblies. Supplied as a single piece with a net weight of 0,027 kg, the elbow from manufacturer Bürkle is intended for non-sterile laboratory material applications where a durable plastic 90° female-thread connector is required. It integrates readily into modular PP piping systems and supports reliable, leak-conscious joints when correctly matched and tightened to compatible fittings.

Questions about 90° bend, inner thread PP, 3/4'', nomin. width 23mm
What is this article?
90° bend, inner thread PP, 3/4'', nomin. width 23mm 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.
