Overview
The ARRMA O-Ring 8x1.5mm (4) Z-ARA716036 is an essential replacement part for RC enthusiasts who demand reliability and precision from their models. Whether you're maintaining a brushless RC monster truck, servicing your RC car UK collection, or keeping your ready to run RC vehicle in top condition, these high-quality silicone O-rings are precisely engineered to meet OEM specifications. O-rings are critical sealing components found throughout RC vehicles, from fuel systems and hydraulic lines to shock absorbers and drivetrain assemblies. Over time, these rubber seals deteriorate through regular use, exposure to fuel, oils, dirt and the demands of off-road RC bashing. Having genuine replacement O-rings on hand ensures you can quickly restore your vehicle to factory performance standards without expensive downtime.
ARRMA has engineered these O-rings from premium-quality silicone rubber to provide exceptional durability and longevity compared to inferior alternatives. The 8mm inside diameter and 1.5mm thickness specification makes these rings compatible with a range of ARRMA models including the legendary BIG ROCK 223S, GRANITE 223S and QUAKE 223S brushless monster trucks and stadium trucks. Each pack contains four replacement O-rings, giving you multiple service opportunities or the ability to stock spares for different vehicles in your RC collection. Whether you're a weekend basher enjoying casual off-road fun or a serious RC hobbyist, maintaining proper seals ensures optimal performance, prevents leaks, and extends the lifespan of critical components.
RC enthusiasts across the UK trust ARRMA components for their proven quality and compatibility. These O-rings represent genuine factory parts manufactured to exacting tolerances, not cheap alternatives that may compromise your vehicle's integrity. The precision manufacturing process ensures fast fit and easy servicing, saving you time during maintenance sessions and allowing you to spend more time enjoying your RC models.

Technical Performance
The ARRMA O-Ring 8x1.5mm represents a critical investment in vehicle maintenance and longevity. O-rings function as precision seals throughout RC vehicles, preventing fluid leaks in fuel systems, hydraulic components, shock absorbers and drivetrain assemblies. The 8mm inside diameter and 1.5mm cross-sectional thickness dimensions are engineered to fit specific factory mounting points on ARRMA brushless RC models, creating reliable seals under operating pressures and temperatures experienced during normal use. The premium silicone rubber material has been selected for its resistance to common RC contaminants including nitro fuel, mineral oils, synthetic oils and petroleum-based products. Unlike inferior rubber materials that swell, harden or deteriorate when exposed to fuel and solvents, quality silicone maintains its elasticity and sealing properties across the temperature range typically encountered in RC driving, from cool British winter conditions to hot summer track sessions. The precision manufacturing process ensures consistent dimensions across all four rings in the pack, critical for achieving uniform sealing performance and preventing leaks that could damage internal mechanisms or reduce vehicle performance.

Frequently Asked Questions
- What is an O-ring and why do I need replacement O-rings for my RC car? — O-rings are rubber sealing rings that prevent fluid leaks in various RC components including fuel systems, shock absorbers, hydraulic lines and drivetrain assemblies. Over time, exposure to fuel, oils, dirt and the pressures of regular RC driving cause these seals to deteriorate, crack or lose elasticity. Worn O-rings lead to fluid leaks, reduced performance and potential damage to internal components. Replacement O-rings restore proper sealing and maintain your vehicle's performance and reliability.
- Are these O-rings compatible with my ARRMA RC model? — These 8x1.5mm O-rings are specifically engineered for ARRMA brushless monster trucks and stadium trucks including the BIG ROCK 223S, GRANITE 223S and QUAKE 223S in all colour variants. If you own one of these models, these genuine ARRMA parts will fit perfectly and restore factory performance. Check your vehicle documentation or contact us if you're uncertain about compatibility with your specific model.
- How often should I replace O-rings on my RC vehicle? — The replacement interval depends on usage frequency and conditions. Regular bashers who drive frequently in dusty or wet environments should inspect O-rings every few months and replace them annually or when visible wear appears. Casual users may only need replacement every two years. Keep spare O-rings on hand so you can replace them immediately if leaks develop, preventing damage to other components.
- What makes ARRMA O-rings better than generic alternatives? — ARRMA O-rings are genuine factory parts manufactured to exact OEM specifications and tolerances, ensuring perfect fit and optimal sealing performance. Generic alternatives may have slightly different dimensions that don't seal properly, potentially leading to leaks and component damage. Genuine parts provide confidence that you're maintaining your vehicle to factory standards and protecting your investment.
- Can I use these O-rings on other RC brands? — These O-rings are engineered specifically for ARRMA vehicles and may not be compatible with other RC brands that use different sealing specifications. Always verify the model number and dimensions before purchasing replacement parts to ensure compatibility with your specific vehicle.
- How do I install these replacement O-rings? — Installation procedures vary depending on which component you're servicing. Generally, you'll need to disassemble the relevant section, remove the old O-ring, clean the sealing surfaces thoroughly, and carefully install the new O-ring without twisting or damaging it. The precision-manufactured dimensions ensure these rings fit properly without requiring force. Consult your vehicle manual for specific installation instructions for the component you're servicing.
