Description
Closure coupling M16x1, FFKM is a laboratory connection component designed for secure closure of temperature-control and fluid-handling lines. It provides an external M16x1 thread and uses an FFKM seal to achieve reliable sealing at the coupling interface. The stated temperature range runs from −45 °C to +220 °C, while the coupling temperature is defined at +20 °C. Manufactured from stainless steel 1.4404/1.4571 or an equivalent material, the body combines mechanical strength with the corrosion resistance expected of these alloys in laboratory service. Laser engraving with the temperature range supports quick visual identification of thermal limits during setup and daily use. Offered as a single piece with a net weight of 0,210 kg, this closure coupling from manufacturer Julabo integrates into baths, circulators and related fluid circuits that rely on M16x1 ports. The FFKM gasket and stainless-steel construction match the wide operating window, helping laboratories blank or terminate open connections when equipment is reconfigured, disconnected or prepared for maintenance without compromising the mechanical integrity of the line.

Questions about Self-sealing coupling M16x1, FFKM temperature range: -45 ... +220 °C
What is this article?
Self-sealing coupling M16x1, FFKM temperature range: -45 ... +220 °C is the article on this page. Luminix Health distributes Julabo for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
