Inner centring ring PTFE DN 10 with Viton O-ring is a precision sealing and alignment component designed for laboratory glassware and apparatus connections of nominal diameter DN 10. The ring is manufactured from chemically resistant PTFE and incorporates a Viton O-ring that provides reliable sealing performance against a wide range of laboratory media. This combination ensures accurate centring of mating parts while maintaining a tight, leak-resistant joint under typical laboratory conditions. Suitable for use as an accessory or spare part in vacuum lines, distillation set-ups, reaction systems and other glass apparatus, the component supports secure assembly and disassembly without compromising chemical compatibility. Offered by manufacturer Rettberg, the inner centring ring is intended for laboratories that require durable PTFE-based sealing solutions with elastomer backup. Its compact design and low net weight facilitate easy handling and integration into existing equipment. The product is supplied as a single piece, ready for immediate installation in research, analytical or process-laboratory environments where reliable DN 10 connections are essential.
