- Universal Compatibility with Key ARRMA Models — These O-rings are compatible with the ARRMA 1/10 Kraton 4X4 4S V2 BLX Speed Monster Truck RTR (both green and standard versions) and the ARRMA 1/10 OUTCAST 4X4 4S V2 BLX Stunt Truck RTR (both red and gunmetal versions), covering some of ARRMA's most popular and highly-regarded RC vehicles.
- Essential Maintenance Component — O-rings are critical sealing elements in RC vehicles that wear out with use, heat exposure, and exposure to fuel or oils, making regular replacement part of responsible RC ownership and long-term vehicle care.
- Professional-Grade Quality — Designed for the demands of RC racing and bashing, these O-rings are manufactured to withstand the pressures, temperatures, and mechanical stresses encountered during high-performance RC driving sessions.
Technical Performance
O-rings are precision elastomer seals engineered to prevent fluid leakage and maintain pressure integrity in the complex mechanical systems of high-performance RC vehicles. The 13x1.5mm specification indicates the seal has a 13mm inner diameter and a 1.5mm cross-sectional thickness, making it suitable for moderate-pressure applications throughout ARRMA's 4WD RC truck range. These seals are found in fuel systems, hydraulic brake lines, transmission housings, and various other critical assemblies where preventing fluid escape is essential to vehicle operation. ARRMA manufactures these O-rings to withstand the demanding conditions of RC driving, including exposure to fuels, oils, temperature variations, and the constant mechanical pressure changes that occur during acceleration, braking, and cornering in RC monster trucks and stunt trucks. The elastomer material used maintains its flexibility and sealing properties across the temperature range typically encountered in RC vehicles, from cold British winters to the heat generated by brushless motors and ESCs during extended driving sessions. Regular inspection and timely replacement of worn O-rings is fundamental to maintaining the reliability and performance of ARRMA RC cars, preventing small leaks from becoming catastrophic failures that could damage internal components or affect your vehicle's handling characteristics.

Frequently Asked Questions
- Which ARRMA RC models use the 13x1.5mm O-ring? — This O-ring size is compatible with the ARRMA 1/10 Kraton 4X4 4S V2 BLX Speed Monster Truck RTR (available in green or standard colour options) and the ARRMA 1/10 OUTCAST 4X4 4S V2 BLX Stunt Truck RTR (available in red or gunmetal versions). If you own either of these popular ARRMA 4WD RC trucks, you should keep spare O-rings on hand for maintenance.
- Why do O-rings need replacing in RC vehicles? — O-rings are elastomer seals that gradually degrade through exposure to fuel, oils, heat, UV light, and the constant mechanical stress of RC driving. Over time, they lose their elasticity and ability to seal properly, which can lead to fluid leaks from fuel systems, hydraulic brake assemblies, and transmission housings. Regular replacement ensures your RC vehicle maintains proper fluid containment and continues to operate reliably.
- How often should I replace O-rings in my ARRMA RC truck? — The replacement frequency depends on your usage patterns and driving conditions. If you notice any fluid leaks from your RC vehicle, immediately inspect and replace any damaged O-rings. Additionally, as part of regular maintenance—such as during a full service after a racing season or after heavy bashing sessions—replacing worn O-rings is good preventive practice that helps avoid more serious mechanical problems.
- Is this suitable for beginners? — Yes, understanding the importance of O-ring maintenance is valuable knowledge for any RC enthusiast, whether you're just starting out in the RC hobby or you're an experienced basher. However, O-ring replacement is typically a task for owners who are comfortable performing basic RC vehicle maintenance. If you're new to RC maintenance, this is a good opportunity to learn from more experienced RC drivers at your local RC club or from online RC communities focused on ARRMA vehicles.
- What is the difference between the 13x1.5mm and other O-ring sizes? — The size designation indicates the inner diameter (13mm) and the cross-sectional thickness (1.5mm). Different ARRMA models and different locations within the same vehicle use different O-ring sizes to suit the specific pressures and spaces in fuel lines, brake systems, and transmission assemblies. It's essential to use the exact size specified for your particular RC model to ensure proper sealing and prevent leaks.
- Are these genuine ARRMA parts? — Yes, these are authentic ARRMA-manufactured O-rings designed and produced to ARRMA's quality standards. Genuine parts ensure compatibility with your RC vehicle and maintain the engineering integrity of your ARRMA model, unlike generic or third-party alternatives.
