Overview
The ARRMA O-Ring, 19x1.5mm (4) is an essential replacement component for RC enthusiasts maintaining their remote control vehicles. Whether you are running an ARRMA RC car UK model or servicing your existing RC setup, these precision-engineered o-rings are critical for maintaining proper seals and preventing fluid leaks in hydraulic and pneumatic systems. Each pack contains four replacement o-rings, making this a cost-effective way to keep your RC vehicle in peak operating condition. For anyone serious about their ready to run RC cars or custom builds, having spare o-rings on hand is simply good maintenance practice.
O-rings are fundamental components found throughout RC vehicles, particularly in suspension systems, gear differentials, and fluid reservoirs. Over time, exposure to heat, pressure, and the elements can cause o-rings to degrade, crack, or lose their sealing properties. When this happens, your RC car may experience fluid leaks, reduced suspension performance, or operational issues. The ARRMA O-Ring, 19x1.5mm (4) Z-ARA716030 provides OEM-quality replacements that restore your vehicle to factory specifications, ensuring reliability whether you are competing at the track or enjoying weekend bashing sessions.
ARRMA is a recognised leader in the RC hobby, manufacturing high-quality components and complete RC vehicles trusted by hobbyists across the UK and worldwide. By choosing genuine ARRMA replacement parts, you are ensuring compatibility with your vehicle and maintaining the engineering standards that ARRMA vehicles are built to. This o-ring pack is suitable for anyone with an ARRMA RC model that requires this specific size specification, from beginners discovering their first RC car to experienced enthusiasts maintaining competition-grade machines.
Key Features
- OEM ARRMA Component — These o-rings are manufactured by ARRMA to original equipment manufacturer specifications, ensuring perfect fit and performance in your RC vehicle without the risk of compatibility issues or poor-quality replacements that could damage your model.
- Precision 19x1.5mm Dimensions — The specific 19mm outer diameter and 1.5mm cross-section thickness are engineered for exact fitment in ARRMA vehicles that require this size, guaranteeing proper sealing and hydraulic performance in critical applications.
- Pack of Four — Each purchase includes four replacement o-rings, providing multiple spares so you can service your vehicle completely or maintain a stock of replacements for future maintenance needs without repeated orders.
- Durable Rubber Compound — ARRMA o-rings are manufactured from high-quality elastomer materials designed to withstand the pressures, temperatures, and chemical exposure typical of RC vehicle operation, including exposure to hydraulic fluids and suspension oils.
- Universal Replacement Solution — Whether you are fixing a leaking differential, resealing a shock absorber, or replacing worn seals in fluid reservoirs, these o-rings provide a universal solution for maintaining your RC vehicle's critical sealing points.
Technical Performance
The ARRMA O-Ring, 19x1.5mm (4) represents precision engineering in miniature form. Constructed from premium elastomer compounds, these o-rings are engineered to maintain their sealing properties across the temperature ranges and pressures experienced in modern RC vehicles. The 19mm outer diameter and 1.5mm cross-sectional thickness are calculated to provide optimal compression and sealing force without creating excessive drag or resistance in the hydraulic systems where they are used. ARRMA's manufacturing standards ensure consistency across every o-ring in the pack, eliminating the variability sometimes found in generic aftermarket seals. These o-rings function across a broad range of hydraulic fluids commonly used in RC suspensions, from lighter silicone oils to thicker damping fluids. The material composition provides resistance to degradation from UV exposure, heat cycling, and the chemical properties of suspension fluids, extending service life and reliability. For RC enthusiasts running high-performance brushless vehicles or engaged in competitive racing, reliable sealing is crucial to maintaining consistent suspension behaviour and preventing fluid loss that could compromise handling characteristics. The pre-packaged quantity of four o-rings allows for comprehensive service of systems containing multiple sealing points or the ability to maintain a spare supply for future maintenance intervals.

Frequently Asked Questions
- What ARRMA RC vehicles use the 19x1.5mm o-ring? — This o-ring size is used in various ARRMA models where specific hydraulic sealing points require a 19mm diameter seal. Check your vehicle's parts diagram or manual to confirm this is the correct replacement for your model. The Z-ARA716030 part number will match your documentation if this is the correct component.
- Why do my RC car o-rings need replacing? — O-rings naturally degrade over time due to heat, pressure cycling, exposure to oils, and UV light. Even properly maintained RC vehicles will eventually experience o-ring deterioration, resulting in fluid leaks, reduced suspension performance, or loss of pressure in sealed systems. Regular replacement is part of standard RC vehicle maintenance.
- How often should I replace my RC vehicle's o-rings? — Replacement frequency depends on usage intensity and operating conditions. Heavily used vehicles or those exposed to extreme temperatures may require o-ring replacement more frequently. Inspect your vehicle regularly for fluid leaks around hydraulic components, which indicate that o-ring seals are no longer effective.
- Will these o-rings fit other RC brands? — Whilst the 19x1.5mm dimension is a standard size, these are ARRMA-branded components optimised for ARRMA vehicles. Generic o-rings of the same dimensions may work, but ARRMA originals ensure exact compatibility and are manufactured to the specifications your vehicle was designed with.
- How do I install replacement o-rings in my RC car? — Most o-ring replacements require disassembly of the component they seal, such as shock absorbers or differentials. Always consult your vehicle's manual for detailed disassembly instructions. Before installation, lightly lubricate the new o-ring with the same fluid your system uses to ensure proper seating and prevent damage during assembly.
- Can I use these o-rings with any hydraulic fluid? — ARRMA o-rings are compatible with standard RC suspension hydraulic fluids, including silicone oils and mineral-based damping fluids commonly available at RC hobby shops. Always use the fluid specification recommended for your vehicle to ensure optimal performance and longevity of seals.
