The DT Swiss O-RING Ø18x2.5mm NBR 70 Shore ISO3601 is a small but essential sealing component designed for use in DT Swiss hub systems and related wheel parts. Made from durable NBR (nitrile rubber) with a 70 Shore hardness, this O-ring provides a reliable balance of flexibility and resistance to wear. It helps keep out water, dust, and dirt, protecting the internal bearings and mechanisms of your hub so they can run smoothly for longer. Replacing worn or damaged O-rings is a simple and cost-effective way to extend the life of your wheels.
This O-ring is manufactured to ISO3601 standards, meaning its dimensions and material properties follow widely recognized industrial specifications. That makes it a dependable choice for maintenance or overhaul of DT Swiss components where this size is required. Whether you are a home mechanic refreshing your wheelset or a workshop technician performing a full hub service, having the correct O-ring on hand ensures a precise fit and consistent sealing performance. Keep your DT Swiss wheels spinning freely and quietly by renewing the small parts that make a big difference.
