Description
Thread adapter Type 35 is a polypropylene (PP) laboratory connector that joins a GL40 female thread to an S55 male thread. It provides a direct mechanical interface between two widely used laboratory thread standards, enabling secure coupling of bottles, caps, tubing assemblies and related fluid-handling hardware. Fabricated from polypropylene, the adapter offers a chemically resistant, lightweight solution for everyday laboratory installations where thread compatibility is required. The Type 35 design from manufacturer SCAT is aimed at workflows that must bridge GL40 and S55 connections without custom machining or multi-part workarounds. Delivered as one piece, the adapter supports straightforward assembly and reliable sealing geometry for solvent, reagent or waste lines. Its PP body is suited to general laboratory environments and helps maintain consistent thread engagement across instruments and storage vessels. Laboratories standardising on GL and S-series threads can use this adapter to streamline equipment configuration and reduce connection mismatches in analytical, preparative and routine bench setups.

Questions about Thread adapter, Type 35
What is this article?
Thread adapter, Type 35 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.
