Overview
The ARRMA O-Ring, 13 x 1.5mm (4) Z-ARA716038 is an essential replacement part for RC enthusiasts in the UK who own ARRMA 4X4 vehicles. These precision-engineered O-rings are designed to maintain optimal sealing performance in hydraulic and pneumatic systems found on high-performance RC cars. Whether you're a weekend basher pushing your RC monster truck to its limits or a serious competitor maintaining your ready to run RC vehicle, having the correct replacement O-rings on hand ensures your model continues to perform at its best.
O-rings are critical components in any RC car, providing watertight seals in shock absorbers, differentials, and fuel systems. Over time, through regular use and exposure to dirt, water and extreme temperatures, these rubber seals can degrade or become damaged. The ARRMA O-Ring, 13 x 1.5mm specification is specifically engineered to fit ARRMA's premium 4X4 RC vehicles, ensuring perfect compatibility and reliable performance. This pack contains four replacement O-rings, giving you multiple seals to repair or maintain your RC truck or buggy.
If you own ARRMA models such as the 1/10 Kraton 4X4 4S V2 BLX Speed Monster Truck RTR or the 1/10 OUTCAST 4X4 4S V2 BLX Stunt Truck RTR, these O-rings are specifically compatible with your vehicle. Sourcing genuine ARRMA parts like this from an authorised UK retailer ensures you're getting authentic components that meet strict quality standards, rather than inferior counterfeit alternatives that could compromise your RC car's performance and longevity.
Key Features
- Pack of Four Replacement O-Rings — You receive four genuine ARRMA O-rings in each pack, providing multiple spare seals so you can repair multiple leak points or keep replacements on hand for future maintenance needs without needing to reorder frequently.
- Precise 13 x 1.5mm Specifications — These O-rings are manufactured to exact specifications of 13mm outer diameter and 1.5mm cross-section thickness, ensuring a perfect fit in the designated seal locations on compatible ARRMA vehicles and preventing leaks that could affect performance.
- Genuine ARRMA Manufacturing — As authentic ARRMA factory parts, these O-rings are engineered to the same quality standards as your RC vehicle, with materials specifically selected for compatibility with ARRMA shock absorbers, differentials and other sealed systems, guaranteeing reliability.
- Improved Seal Performance — Replacing worn or damaged O-rings immediately restores hydraulic system integrity in your RC car, improving shock absorption, differential performance and preventing fluid leakage that would otherwise degrade your vehicle's handling characteristics.
- Cost-Effective Maintenance — Rather than replacing entire assemblies when seals fail, these replacement O-rings offer an economical way to restore your RC car to full working order, extending the lifespan of your expensive RC components and saving money on repairs.
- Compatible with Multiple ARRMA 4X4 Models — These O-rings fit ARRMA 1/10 Kraton 4X4 4S V2 BLX Speed Monster Truck RTR variants and ARRMA 1/10 OUTCAST 4X4 4S V2 BLX Stunt Truck RTR models in multiple colour options, making them a versatile spare part for any ARRMA 4X4 enthusiast in the UK.
Technical Performance
The ARRMA O-Ring, 13 x 1.5mm (4) is engineered using high-quality elastomer materials specifically formulated to withstand the demanding conditions found in modern RC vehicles. These seals are designed to maintain their integrity across a wide temperature range, crucial for RC cars that operate in varying UK weather conditions from cold winter months to hot summer bashings. The 13mm diameter and 1.5mm cross-section represent a specific sizing requirement in ARRMA's engineering design, and using non-genuine or incorrectly-sized O-rings can result in leaks, reduced shock performance and potential damage to internal seal grooves. The elastomer compound is resistant to the hydraulic fluids, silicone oils and lubricants commonly used in modern RC shock absorbers, ensuring long-term compatibility and preventing degradation from chemical exposure. These O-rings play a critical role in maintaining system pressure within shock absorbers and differentials, which directly impacts the suspension geometry, handling balance and overall performance of your ready to run RC truck or buggy. When seals fail, fluid leakage becomes visible on your vehicle, shock performance becomes unpredictable, and differential function may be compromised. By maintaining a stock of these genuine replacement O-rings, you can perform preventative maintenance or quickly repair seal failures, ensuring your ARRMA RC car remains in peak racing condition.
What's in the Box
- 4 x ARRMA O-Ring 13 x 1.5mm
Frequently Asked Questions
- What is the 13 x 1.5mm specification on these O-rings? — The 13 x 1.5mm refers to the O-ring's outside diameter of 13 millimetres and the thickness of the rubber cross-section at 1.5 millimetres. This specific sizing is engineered to fit into the seal grooves found in ARRMA shock absorbers, differentials and other hydraulic components on compatible 4X4 RC vehicles. Using the correct size is essential because an oversized O-ring will not seal properly and an undersized one will fall out of its groove, resulting in leaks.
- Which ARRMA RC cars do these O-rings fit? — These O-rings are compatible with the ARRMA 1/10 Kraton 4X4 4S V2 BLX Speed Monster Truck RTR (both standard and green colour variants) and the ARRMA 1/10 OUTCAST 4X4 4S V2 BLX Stunt Truck RTR (both gunmetal and red colour variants). If you own one of these ARRMA 4X4 models, these O-rings are specifically engineered for your vehicle.
- How often should I replace the O-rings on my RC car? — O-ring replacement is a maintenance task required when you notice visible fluid leaks from your shock absorbers, when shock performance becomes noticeably softer or inconsistent, or during regular service intervals on heavily-used RC cars. Many serious RC competitors replace O-rings preventatively every season or after intensive racing to ensure peak performance, whilst casual weekend bashers may go longer between replacements depending on usage and environmental conditions.
- Are these genuine ARRMA parts? — Yes, these are authentic ARRMA factory-manufactured O-rings, not third-party alternatives. Genuine ARRMA parts are engineered to exact specifications and made with materials that precisely match your vehicle's design requirements, ensuring compatibility, reliability and longevity. Sourcing genuine spare parts from authorised UK retailers protects your investment in your RC car.
- Can I use these O-rings on other RC brands? — Whilst the 13 x 1.5mm sizing might theoretically fit other RC brands, we only recommend these for genuine ARRMA vehicles. Other manufacturers use different seal groove specifications and elastomer compounds optimised for their designs, so cross-brand substitution is not recommended and could result in poor sealing performance or component damage.
- How many O-rings are in this pack? — This pack contains four replacement O-rings, giving you multiple seals for different maintenance tasks or to keep backups on hand for future repairs without needing to reorder from your UK RC retailer.
