Description
Thread adapter Type 49 is a polypropylene (PP) laboratory fitting that converts an S51 female thread to an S55 male thread, enabling reliable connections between containers and accessories that employ these two thread standards. The adapter allows laboratory bottles or vessels fitted with S51 necks to interface directly with S55-threaded caps, connectors or transfer components. Constructed from polypropylene, it provides a practical mechanical link for solvent supply lines, sample reservoirs and general fluid-handling arrangements. Type 49 from manufacturer SCAT is delivered as a single piece and is intended for everyday laboratory use where rapid, secure thread conversion is required. The fitting supports chromatography solvent systems, analytical sample preparation and closed-container workflows by eliminating the need for improvised or multi-part adapters. Its simple geometry facilitates quick installation and removal during method changes or equipment reconfiguration. Laboratories working with mixed bottle and closure inventories benefit from this direct S51-to-S55 transition, which helps maintain organised fluidic setups and reduces potential connection points in chemical and life-science environments.

Questions about Thread adapter, Type 49
What is this article?
Thread adapter, Type 49 is the article on this page. Luminix Health distributes SCAT 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.
