Description
Thread adapter Type 33 is a polypropylene (PP) laboratory fitting that converts a 1,5'' Sakura Tissue Tek female thread to an S55 male thread. This dedicated interface piece allows equipment and vessels with different thread standards to be joined securely in routine laboratory fluid-handling setups. Made entirely of polypropylene, the adapter combines chemical resistance with a lightweight, easy-to-handle form that simplifies installation and change-over. The Type 33 geometry from manufacturer SCAT is intended for laboratories that need a reliable plastic thread conversion between Sakura Tissue Tek style connections and S55 threaded components. Supplied as a single piece, it supports clean, repeatable coupling without improvised fittings or adapters of mixed materials. Typical use includes solvent lines, waste collection paths and general bench or instrument connections where standardised thread matching improves system integrity. The PP construction keeps the component durable under normal laboratory conditions while remaining straightforward to integrate into existing manifolds and bottle systems that rely on these common thread formats.

Questions about Thread adapter, Type 33
What is this article?
Thread adapter, Type 33 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.
