Overview
The ARRMA O-Ring, 14 x 1.2mm (4) is an essential replacement part for RC enthusiasts who demand reliability and precision in their high-performance vehicles. Whether you're running a 1/5 scale brushless monster truck or stunt truck, these genuine ARRMA o-rings are engineered to maintain critical seals in fuel systems, hydraulic lines, and pneumatic components. For RC car UK enthusiasts, having spare o-rings on hand is a mark of responsible maintenance and ensures your ready to run RC vehicle stays in peak condition between runs.
O-rings are small but absolutely vital components in any RC vehicle. They create watertight and airtight seals in connectors, fittings, and fuel line systems, preventing leaks that could damage your RC car's engine or hydraulic systems. The 14 x 1.2mm specification makes these o-rings suitable for a range of ARRMA vehicles, particularly their larger scale models like the 1/5 Kraton and Outcast ranges. These are genuine manufacturer parts, not cheap imitations, so you can trust that they'll perform reliably under the demanding conditions of competitive racing or casual bashing.
This pack contains four individual o-rings, giving you multiple spares to keep your fleet of RC vehicles running smoothly. Brushless RC trucks and monster trucks put serious demands on every component, and fuel system reliability is non-negotiable. Stock these replacement o-rings in your spares box and you'll never be caught without a critical seal when you need it most.
Key Features
- Genuine ARRMA manufacture — These o-rings are produced by ARRMA themselves, ensuring perfect fitment and performance with your compatible RC models, rather than relying on generic aftermarket parts that may not meet the same quality standards.
- Pack of four — You receive four o-rings in each pack, providing multiple spare units so you can replace worn seals without running out of spares before your next order arrives.
- Precise 14 x 1.2mm dimensions — The exact size specification ensures these o-rings fit perfectly in their intended applications, maintaining critical seals in fuel systems and hydraulic lines without gaps or excessive compression.
- Compatible with high-performance ARRMA vehicles — These o-rings are engineered to work with ARRMA's most powerful brushless RC trucks, including the 1/5 scale Kraton 4X4 8S BLX EXB and Outcast 4X4 8S BLX EXB models, which demand the highest-quality components.
- Essential maintenance part — Fuel and hydraulic seals degrade over time due to heat, UV exposure, and chemical attack from fuels and oils, making regular o-ring replacement a critical part of responsible RC ownership.
- Affordable spares solution — Replacement o-rings cost a fraction of the price of major repairs, making preventative maintenance with quality spares an excellent investment in protecting your more expensive RC vehicles.
Technical Performance
The ARRMA O-Ring, 14 x 1.2mm represents precision engineering in a small package. With a 14mm outer diameter and 1.2mm cross-sectional thickness, these o-rings are sized for specific fitting applications in ARRMA's high-performance brushless RC trucks. The engineering behind o-ring design might seem straightforward, but it's actually quite sophisticated — the cross-sectional diameter must be precise enough to create an effective seal without being compressed so tightly that it becomes difficult to install or prone to extrusion. ARRMA's manufacturing standards ensure that each o-ring meets strict tolerances for diameter, thickness, and material composition. These o-rings work in demanding conditions found in fuel systems of brushless monster trucks and stunt trucks, where they must withstand pressure variations, temperature fluctuations, and exposure to fuel chemicals. The material composition provides excellent resistance to degradation whilst maintaining flexibility for proper sealing. Whether you're maintaining a 1/5 scale Kraton or Outcast brushless truck, these o-rings are engineered to perform reliably under the intense pressures and temperatures generated during high-speed runs and competitive racing scenarios.

Frequently Asked Questions
- What vehicles are these ARRMA o-rings compatible with? — These 14 x 1.2mm o-rings are compatible with the ARRMA 1/5 Kraton 4X4 8S BLX EXB Brushless Monster Truck RTR and the ARRMA 1/5 Outcast 4X4 8S BLX EXB Brushless Stunt Truck RTR. Always check your vehicle's manual or parts diagram to confirm which o-ring sizes your specific model requires, as ARRMA produces o-rings in numerous sizes for different applications.
- Why do I need replacement o-rings for my RC truck? — O-rings create critical seals in fuel systems, hydraulic lines, and pneumatic fittings. Over time, they degrade due to heat exposure, UV radiation, chemical attack from fuels, and the natural wear that occurs during operation. Replacing degraded o-rings prevents fuel leaks, maintains system pressure, and protects your expensive RC vehicle from damage.
- How often should I replace o-rings on my brushless RC truck? — This depends on how frequently you run your RC car and how harshly you use it. Competitive racers might replace o-rings every few months, whilst casual weekend bashers might go longer. Inspect o-rings regularly for signs of cracking, hardening, or loss of elasticity. If you notice any fuel leaks or seepage around fittings, replace the o-rings immediately.
- Are genuine ARRMA o-rings worth buying instead of generic alternatives? — Yes, absolutely. Genuine ARRMA parts are engineered to exact specifications for your vehicle and are manufactured to consistent quality standards. Cheap generic o-rings may look similar but often have slightly different dimensions, inferior material composition, or inconsistent quality, leading to poor seals and potential fuel leaks that could damage your RC engine.
- How many o-rings should I keep in stock? — This pack provides four o-rings, which is a good starting point for your spares box. If you run multiple ARRMA vehicles or compete regularly, consider stocking several packs to ensure you never run out during a maintenance session or after a fuel system failure.
