Essential for maintaining Husqvarna DM 400 and DM 430 core drill operators working on commercial job sites where equipment downtime costs money. This RDR36x3 O-ring serves as a critical seal component in the drill's hydraulic system, preventing fluid leaks that can compromise drilling performance and damage internal mechanisms. Regular replacement of worn O-rings keeps your core drill operating at full capacity during demanding concrete cutting applications. The part installs quickly with basic hand tools, getting your drill back in service without extended shop time. Factory-engineered to exact specifications for proper fitment and reliable sealing performance. Keep spares in your service kit to avoid delays when seals fail during foundation work, slab penetrations, or utility installations. Built for concrete cutting professionals and equipment maintenance crews who service Husqvarna core drilling equipment.
