Description
Inner centring ring/PTFE DN 40 with Viton O-ring is a precision sealing component intended for accurate alignment and reliable sealing of laboratory flange connections. The PTFE construction offers superior chemical resistance while the integrated Viton O-ring supplies the necessary elasticity for a tight, reusable seal at the DN 40 size. Weighing only 0,010 kg net, the ring remains lightweight yet mechanically stable for everyday use in glassware, vacuum and process apparatus. It functions equally well as an original part or as a replacement spare within existing laboratory systems. Manufactured in Germany under the Rettberg ® trademark and supplied by manufacturer Rettberg, the component belongs to the seals product category. Its design supports leak-free joints in chemical synthesis, analytical instrumentation and research environments where inert materials and long service life are required. Packaged as 1 pc, the ring enables straightforward ordering for maintenance or new assemblies, helping laboratories maintain system integrity and minimise downtime caused by worn or missing centring seals.

Questions about Inner centering ring/PTFE DN 40, with Viton-O-Ring
What is this article?
Inner centering ring/PTFE DN 40, with Viton-O-Ring is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Other instruments & spare parts, in Lab instruments.
Some instruments do not sit cleanly in one measuring principle, and every instrument eventually needs a spare: a lamp, a fuse, a seal, a knob. The spare has to be the part for that model. A near match is a different part. Calibration of the instrument, once it measures, belongs with EURAMET, BELAC and the BIPM.
