HoBao O-Ring Seal 6mm Outer Diameter 1mm Cross-Section 5 Pack H36109

Overview

The HoBao O-Ring 6x1mm (Part number H36109) is an essential spare component for RC enthusiasts maintaining and repairing their HoBao RC vehicles. This pack contains five genuine O-rings, each measuring 6mm in outer diameter with a 1mm cross-section, making them a crucial wear item for any serious RC car UK collector or regular basher. Whether you're running a competition-grade RC buggy, a weekend off-road crawler, or any HoBao-powered RC model, these O-rings are fundamental to keeping your vehicle performing at its best.

O-rings serve a critical sealing function in RC vehicles, preventing fluid leakage and maintaining pressure in various drivetrain and engine components. Over time, through repeated use, heat cycles, and exposure to fuel or oil, O-rings naturally degrade and lose their elasticity. Having a spare pack of five O-rings means you'll always be prepared for maintenance without interrupting your RC racing or bashing sessions. For anyone serious about maintaining their ready to run RC car or custom-built machine in peak condition, these authentic HoBao spares are an indispensable addition to your toolkit.

Purchasing genuine manufacturer parts like these HoBao O-rings ensures perfect compatibility with your specific RC model and maintains the integrity of your vehicle's sealing systems. Rather than risking mismatched aftermarket alternatives that could lead to leaks or performance issues, investing in original HoBao spares guarantees reliable performance and peace of mind.

Key Features

• Genuine HoBao Manufacturer Part — These O-rings are authentic HoBao spare components, ensuring perfect compatibility with HoBao RC vehicles and guaranteed quality standards that third-party alternatives cannot match.
• Six Millimetre Outer Diameter — The 6mm sizing is precisely engineered for specific sealing applications within HoBao RC drivetrains and transmission systems, ensuring optimal fit and function.
• One Millimetre Cross-Section — The 1mm wall thickness provides the correct durometer and flexibility needed for effective sealing whilst maintaining durability under the pressures and temperatures generated during RC vehicle operation.
• Pack of Five Units — With five O-rings in each pack, you have multiple replacement options, allowing you to service multiple components or maintain a reserve supply for future maintenance needs without needing to reorder frequently.
• Essential Wear Item — O-rings gradually deteriorate through normal use, heat exposure, and contact with fuels or oils, making regular replacement a necessary part of responsible RC vehicle maintenance and longevity.
• Affordable Spare Parts Solution — Priced accessibly at just £1.66, this pack represents cost-effective vehicle maintenance, allowing hobbyists to keep their RC cars in top condition without significant expense.

Technical Performance

O-rings are precision-engineered elastomeric seals that play a vital role in the mechanical integrity of RC vehicles. The 6x1mm specification indicates an outer diameter of 6 millimetres with a 1-millimetre cross-sectional thickness, creating a ring profile that fits into grooves and between mating surfaces to prevent fluid leakage. In HoBao RC applications, these seals are typically found in transmission components, differentials, and various drivetrain assemblies where they must withstand moderate pressures, heat generated by friction, and exposure to lubricating oils or fuel residue. The elastomer material used in genuine HoBao O-rings is formulated to maintain flexibility across the temperature ranges experienced during typical RC driving sessions, from room temperature assembly through to the elevated heat of extended running periods. Unlike inferior replacement O-rings that may harden prematurely or swell excessively when exposed to petroleum-based lubricants, genuine HoBao spares are engineered for durability and consistent performance. The one-millimetre wall thickness represents an optimal balance between sealing effectiveness and material flexibility, ensuring the O-ring can conform to the surfaces it seals without becoming overly rigid. Regular inspection and replacement of O-rings as part of routine RC vehicle maintenance prevents leaks that could compromise differential operation, transmission efficiency, or other critical systems.

Frequently Asked Questions

• Why do I need to replace O-rings on my HoBao RC car? — O-rings are elastomeric seals that gradually lose their flexibility and effectiveness through normal use, heat cycles, and exposure to oils and lubricants. Over time, they may harden, crack, or become permanently deformed, leading to leaks in transmission, differential, or drivetrain components. Regular replacement during scheduled maintenance prevents these leaks and maintains the integrity of your RC vehicle's mechanical systems.
• How often should I replace O-rings on my HoBao RC vehicle? — The replacement interval depends on usage frequency and intensity. For regular bashers, inspecting and replacing wear-prone O-rings every 10-15 hours of running time is a sensible precaution. Competition users may need more frequent replacement due to sustained high-load operation. Always inspect O-rings when servicing transmissions or differentials, and replace any that show signs of hardening, cracking, or permanent deformation.
• Are these genuine HoBao parts? — Yes, these O-rings are authentic HoBao manufacturer spares identified by part number H36109. Purchasing genuine parts ensures perfect compatibility with your HoBao RC vehicle and maintains the manufacturer's engineering standards and quality control. Avoid counterfeit or generic alternatives that may not fit correctly or perform reliably.
• What HoBao RC models use 6x1mm O-rings? — The 6x1mm specification is a common sizing across various HoBao RC vehicle models including buggies, trucks, and other platforms where transmission or differential sealing is required. Check your specific HoBao vehicle's service manual or parts diagram to confirm that H36109 is the correct part number for your model.
• Can I use non-HoBao O-rings instead? — Whilst generic O-rings may appear similar, there are risks with using non-manufacturer alternatives. They may be formulated with different elastomer compounds that behave differently with HoBao-approved lubricants, potentially swelling, hardening, or becoming ineffective more quickly. Genuine HoBao parts are engineered specifically for your vehicle, and using them eliminates compatibility uncertainties.
• How should I install these O-rings? — Before installation, ensure the groove and mating surfaces are clean and free from debris or old elastomer residue. Apply a light coat of the appropriate lubricant (typically silicone or petroleum-based grease depending on your HoBao vehicle type) to the O-ring to aid seating. Gently roll the O-ring into its groove, ensuring it sits evenly without twisting or bunching. Consult your HoBao vehicle's assembly guide for specific component-level installation instructions.
