Compatible Canon Zoom Lenses

This wear-resistant rubber dust ring fits Canon 24-70, 70-200, 17-40 and 16-35II zoom lenses. It replaces a damaged or missing original seal at the lens mount. The 6.3 cm diameter matches the specified mount size for these models. Photographers who need a direct replacement for a worn ring will find it suitable.

Protection From Dust And Moisture

The rubber ring seals the lens mount against dust, moisture and water ingress during use and storage. Its replaceable design lets you restore the factory weather protection without sending the lens for service. The package contains one ring only; no tools, lubricants or additional seals are included. Buyers who expect a multi-ring kit or a complete lens overhaul set should look elsewhere.

Simple Press-fit Installation

Installation is a straightforward press-fit onto the lens mount flange; no adhesives or screws are required. Careful alignment prevents the ring from binding or sitting unevenly, which is the most common fitting issue. The material is flexible but can stretch if forced, so gentle pressure is advised. Technicians who need a threaded or adhesive-mounted seal will not be able to use this ring.

Questions about this item

Will the rubber ring need replacing again after a certain period?

The ring is made of wear-resistant rubber and serves as a replaceable repair part; it can be swapped again if it degrades.

What is the first limit reached during continuous daily use?

The 6.3 cm diameter fit is the critical limit — if the mount stretches beyond this size the seal will no longer block dust and moisture.

Does the ring affect lens temperature or generate any noise during all-day shooting?

No, the passive rubber seal adds no heat, noise or power draw; it simply maintains a dust-proof barrier around the mount.
