Description
Screw fitting with internal thread in polypropylene (PP) provides a practical connector for laboratory tubing and pipework where quick assembly and simple disconnection are required. Sized at 1/2'' with a nominal width (NW) of 17,5 mm, the fitting is intended for fluid-handling setups, sampling lines, and general laboratory installations that use matching threaded components. The internal-thread design enables straightforward loosening of pipe connections without complex tooling, supporting flexible reconfiguration of temporary or semi-permanent circuits. Made from PP, the component suits many aqueous and mild chemical media typical of analytical, process, and pilot-scale work. This screw fitting from manufacturer Bürkle is offered as a single piece with a net weight of 0,058 kg, making it easy to stock as a spare or standard connector. It complements stands, tubing systems, and modular fluid paths in research, quality control, and industrial laboratory environments that need reliable plastic fittings with defined thread and bore dimensions for repeatable installation.
This article is part of Hose connectors, adapters & fittings, in Tubing, hoses & fittings.

Questions about Screw joint, inner thread, PP, 1/2'', NW 17,5 mm
What is this article?
Screw joint, inner thread, PP, 1/2'', NW 17,5 mm 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.
