These premium silicone O-rings are precision-engineered to provide consistent fitment and smooth operation, making them an indispensable maintenance item for anyone running ARRMA's cutting-edge brushless RC vehicles. Whether you're racing a high-speed street RC car, bashing over rough terrain, or competing in organised events, having quality replacement O-rings in your spares kit ensures your RC model stays in peak condition and ready for action.
O-rings are critical components found throughout modern RC cars and trucks, used to create watertight seals, maintain structural integrity, and ensure smooth mechanical operation across a wide range of drivetrain and chassis systems. The ARRMA O-Ring P-3 represents the manufacturer's commitment to providing genuine, OEM-quality spare parts that meet the demanding requirements of competitive RC driving and recreational bashing alike. With a pack of four rings per purchase, you'll have multiple replacements on hand, reducing downtime and keeping your RC hobby moving forward without interruption.
Manufactured by ARRMA, a brand recognised worldwide for its high-performance brushless RC vehicles including the Infraction, LIMITLESS, MOJAVE, and TALION ranges, this replacement part carries the assurance of genuine OEM engineering. RC model shop enthusiasts in the UK trust ARRMA parts because they're designed specifically for compatibility with their vehicles, ensuring perfect fitment and reliable long-term performance.
Key Features
- High-quality silicone construction — These O-rings are manufactured from premium-grade silicone that resists degradation from exposure to oils, fuels, and environmental contaminants, ensuring they maintain their seal integrity and flexibility over extended periods of use.
- Precise dimensional specification — With an outside diameter of 3.5mm and a thickness of 1.9mm, these O-rings are engineered to exact tolerances, guaranteeing a perfect fit on ARRMA components and eliminating leaks or mechanical slippage.
- Pack of four rings — This pack includes four replacement O-rings, providing you with multiple spares so you can replace worn components immediately without waiting for additional orders, keeping your RC vehicle in service.
- Genuine OEM compatibility — Designed and manufactured by ARRMA specifically for use across multiple vehicle models including the Infraction 6S BLX, LIMITLESS 8S AVC, MOJAVE 6S V2 BLX, and TALION 6S EXB platforms, ensuring authentic fitment and performance.
- Smooth operation assurance — The silicone material provides consistent, smooth mechanical performance, reducing friction and wear on adjacent components while maintaining reliable sealing properties throughout the vehicle's drivetrain and chassis systems.
- Red colour identification — The distinctive red colour makes these O-rings easy to identify in your spares collection and helps with quick visual checks during maintenance routines.
Technical Performance
The ARRMA O-Ring P-3 3.5x1.9mm represents precision engineering at the component level, where attention to detail directly impacts overall vehicle performance and reliability. O-rings serve multiple critical functions across modern brushless RC vehicles: they create watertight seals in differentials and transmission housings, maintain compression in shock absorbers, secure drivetrain components, and prevent fluid leakage that could compromise mechanical systems. The high-quality silicone material specified for this product provides superior resilience compared to standard rubber compounds, maintaining elasticity and seal effectiveness across a wider temperature range and after prolonged exposure to RC-specific oils, silicone lubricants, and environmental moisture. The precise 3.5mm outer diameter and 1.9mm thickness specification ensures these rings fit snugly on ARRMA's engineered mounting points, eliminating wobble or misalignment that could lead to premature wear or seal failure. Whether you're running a high-speed street RC car like the MOJAVE 6S V2 BLX in competitive time trials, pushing an 8S-powered extreme performance vehicle like the LIMITLESS 8S AVC 4X4 RTR to its limits, or maintaining a mid-range performer like the TALION 6S EXB speed truck for regular weekend bashing, these O-rings deliver the consistent performance and reliability expected from authentic ARRMA components. The silicone construction resists degradation from contact with differential oils, shock fluid, and brake fluid, extending service life and maintaining reliable sealing properties throughout multiple racing seasons or extended recreational use.

Frequently Asked Questions
- Which ARRMA RC cars and trucks are compatible with the O-Ring P-3 3.5x1.9mm? — These genuine ARRMA O-rings are designed for use with multiple high-performance models including the Infraction 6S BLX in both Blue and Silver colour variants, the 1/7 LIMITLESS 8S AVC 4X4 RTR in both White/Blue and Red/Black street speed configurations, the MOJAVE 6S V2 BLX in Green/Black and Red/Black colours, and the 1/7 TALION 6S EXB 4X4 RTR speed truck in black. Check your vehicle's parts diagram or service manual to confirm the specific mounting locations for these O-rings on your model.
- Why do I need replacement O-rings for my RC vehicle? — O-rings gradually lose their elasticity and sealing effectiveness through regular use, exposure to oils and lubricants, and thermal cycling during extended RC sessions. Replacing worn O-rings prevents fluid leaks from differentials and transmissions, maintains proper shock absorber function, and prevents dirt and moisture ingress into sealed mechanical systems. Having spare O-rings in your maintenance kit allows you to perform preventative maintenance and quickly address any leaks or seal failures that develop during racing or bashing.
- How often should I replace O-rings on my RC car or truck? — The replacement interval depends on how frequently you use your RC vehicle, the conditions you drive in, and the type of oils and lubricants you use. As a general guideline, inspect O-rings during each major maintenance session or after every 10-15 hours of driving time. Replace any rings that show visible cracks, permanent deformation, hardening, or loss of elasticity. If you notice fluid leaks from sealed components, immediate O-ring replacement is recommended.
- Are these genuine ARRMA parts? — Yes, these are authentic OEM ARRMA component manufactured to the brand's exact specifications. They carry the official ARRMA part number Z-AR330245 and are distributed through authorised ARRMA retailers. Using genuine OEM parts ensures perfect compatibility with your vehicle and maintains the engineering integrity of your RC model's sealed systems.
- What tools do I need to replace these O-rings? — Most O-ring replacements require only basic RC maintenance tools: a small screwdriver set, hex wrenches appropriate to your vehicle, and potentially an Allen key to access sealed components. Refer to your ARRMA vehicle's service manual for specific disassembly instructions and torque specifications. Having a small container of the appropriate differential oil or shock fluid on hand is also recommended if you're servicing sealed differentials or shock absorbers.
- Can I use these O-rings on other RC brands or vehicles? — These O-rings are specifically engineered for ARRMA vehicles using the P-3 designation and 3.5x1.9mm dimensions. While similar O-rings might fit other brands, using genuine ARRMA parts ensures perfect compatibility and maintains your vehicle's performance warranty. For other RC brands, consult your vehicle's parts catalogue or contact the manufacturer directly for the correct part numbers.
