Key benefits Reliable tubeless fit: Designed specifically as a tubeless tire valve, it provides a secure seal for tubeless tires on electric bikes and other electric vehicles, reducing air loss and maintenance. Safer operation: The valve body is made of copper and engineered for anti-explosion resistance, helping protect the tire and rider under normal operating pressures. Long-lasting airtightness: Metal/copper construction delivers strong resistance to wear and maintains airtight performance over time, improving durability and effectiveness. Superior seal material: The valve head uses imported EPDM rubber with high tensile strength and excellent aging resistance, ensuring a consistent, flexible seal that resists cracking and hardening. What it does and why you need it Seals tubeless tire systems to prevent slow leaks and maintain proper tire pressure, which improves ride stability, battery efficiency on electric vehicles, and reduces the need for frequent top-ups. Provides a metal, explosion-resistant valve core for added safety compared with lower-grade materials. Combines durable metal housing with an EPDM rubber head to balance strength and sealing performance, extending service life and reducing replacement frequency. Materials and performance Valve body: copper/metal for impact and pressure resistance; designed to resist rupturing under typical electric vehicle and e-bike pressures. Valve head: imported EPDM rubber offering strong tensile strength and high resistance to aging, ozone and temperature-related degradation. Airtightness: constructed to minimize air leakage and maintain reliable pressure retention in tubeless setups. Compatibility and function Intended for tubeless tire applications on electric bikes and other electric vehicles that use tubeless valve stems. Fits standard tubeless valve ports and acts as a direct replacement for worn or damaged tubeless valves (verify stem diameter and length with your wheel specifications before purchase). Functions: air inlet/outlet for inflation, airtight sealing, and pressure containment with enhanced safety from copper anti-explosion design. Practical use scenarios Daily e-bike commuter: Keeps tire pressure stable for consistent handling and longer range between charges, reducing roadside top-ups. Cargo or delivery e-scooter: Durable construction and improved airtightness reduce downtime and maintenance costs for vehicles with heavy usage. Small electric vehicle or mobility device: Provides a safer, longer-lasting valve solution for tubeless wheels used in frequent short trips or shared/multi-user settings. What to expect A tubeless valve assembly combining a copper/metal body and an EPDM rubber head, designed for reliable sealing, improved durability, and added safety in electric bike and electric vehicle applications. Improved airtightness and resistance to aging compared with basic rubber-only valves, resulting in fewer replacements and more consistent tire pressure.
