Overview
The ARRMA O-Ring, 9x2mm (4) Z-ARA716028 is an essential replacement component for serious RC enthusiasts maintaining their high-performance brushless RC models.

Whether you're running a competitive setup or enjoying weekend bashing sessions with your RC car UK, having spare o-rings on hand is crucial for keeping your model in peak condition and avoiding unexpected downtime during races or track sessions.

Technical Performance
The ARRMA O-Ring, 9x2mm specifications deliver the precision sealing performance demanded by 1/5 scale brushless RC trucks operating at high speeds and under demanding conditions. These o-rings are manufactured from premium elastomer materials engineered to withstand repeated compression cycles, extreme temperature variations, and exposure to fuels and oils common in RC applications. The 9mm inner diameter with 2mm cross-section provides optimal flexibility and compression characteristics for the medium-duty sealing applications found throughout ARRMA's brushless monster truck and stunt truck range. Construction quality ensures reliable performance across extended driving sessions, whether you're running competitive race events or recreational bashing, with the elastomer formulation resisting degradation from environmental exposure and fluid contact. Engineers and builders appreciate the consistency of these components, knowing that genuine OEM o-rings maintain their seal integrity far better than inferior aftermarket alternatives, ultimately protecting more expensive internal components and reducing total cost of ownership for your ready to run RC investment.
