Description
Thread adapter, Type 91 is a polypropylene (PP) laboratory fitting that converts an S41 female thread to a GL45 male thread. It provides a reliable mechanical interface when bottles, canisters or safety caps with different neck finishes must be connected in solvent handling, waste collection or general laboratory fluid systems. The chemically resistant polypropylene body suits routine exposure to many common laboratory solvents and reagents while remaining lightweight and easy to handle. Type 91 from manufacturer SCAT is intended for everyday analytical and preparative setups that rely on standardised laboratory container threads. The adapter supports secure, leak-resistant transitions without specialised tools, simplifying assembly and changeover during vessel exchange or system reconfiguration. Its compact form integrates cleanly into existing collection and safety-cap arrangements. Supplied as a single piece, the unit is ready for immediate installation wherever an S41-to-GL45 thread conversion is required. Clear thread geometry helps maintain consistent alignment and sealing performance in day-to-day laboratory operations, making the adapter a practical component for organised solvent and waste management workflows.

Questions about Thread adapter, Type 91
What is this article?
Thread adapter, Type 91 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 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.
