Husqvarna 598736801 O-Ring RDR32x3 Spare Part DM 400, DM 430

When your Husqvarna DM 400 or DM 430 core drill develops a leak at the water system, this RDR32x3 O-ring gets you back to drilling without downtime. This factory-spec replacement part maintains proper water flow to your diamond bit during operation, preventing overheating and extending bit life on deep concrete penetrations. The O-ring seals critical connections in the drill's water delivery system, which keeps dust down and your crew working efficiently on multi-hole jobs. Manufactured to Husqvarna's specifications, this component ensures compatibility with your existing equipment. Stock a few in your service kit to avoid job delays when seals wear out from regular use. Built for concrete cutting contractors and facility maintenance teams running Husqvarna DM-series drills who need genuine replacement parts on hand.
