Description
Sealing screw fittings M38x1,5 are compact closure components for laboratory fluid and temperature-control circuits. This set comprises two sealing screw fittings with an M38x1,5 thread, intended to close matching ports securely when lines are unused or during system reconfiguration. The pair has a net weight of 0,420 kg and supports leak-tight sealing on compatible connections used with baths, circulators and related thermal equipment. Produced by manufacturer Julabo, the fittings suit routine maintenance, temporary isolation of unused ports and orderly shutdown of process loops in research and quality-control laboratories. Metric M38x1,5 geometry ensures straightforward mating with corresponding ports and accessories built to the same standard. Their robust construction is appropriate for repeated assembly and disassembly in everyday laboratory workflows. Originating from Germany, these sealing screw fittings provide a practical hardware option for laboratories that need reliable port closure without complex tooling, helping keep open connections protected from contamination and unintended fluid loss during setup changes or idle periods.

Questions about 2 Collar nuts M38x1.5
What is this article?
2 Collar nuts M38x1.5 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.
