Description
Clean-Break shut-off coupling M30x1,5 with FFKM seal is a stainless-steel fluid connector for temperature-controlled laboratory and process circuits. It uses bilateral shut-off Clean-Break technology for low-loss, low-inclusion coupling and uncoupling of lines. The external thread connection is M30x1,5. The operating temperature range is -45 °C to +220 °C, with a specified coupling temperature of +20 °C. Housing materials are stainless steel 1.4404/1.4571 or equivalent, combined with an FFKM sealing element for demanding media. Laser engraving marks the temperature range for clear identification in service. Offered as one piece with a net weight of 1,470 kg, this coupling from manufacturer Julabo suits recirculating chillers, thermostats and closed temperature-control loops where clean disconnection and reliable sealing are required. The Clean-Break design helps limit fluid loss and air inclusion during connection changes, supporting stable process conditions in research and industrial laboratory environments that rely on secure, repeatable fluid interfaces.

What is this article?
Clean-Break self-sealing coupling M30x1.5, FFKM temperature range: -45 ... is the article on this page. Luminix Health distributes Julabo 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.
