TIESOME 4PCS 90 Degree Metal Valve Stem Extenders, Universal Valve Stem Extensions for Dual Wheels Passenger Cars Vehicles

Features

• 【Secure 90-Degree Design】The 4 pcs 90 degree tire valve extensions solve accessibility issues in tight spaces between spokes, rims, or wheel covers. The right-angle bend aligns seamlessly with air pump nozzles, enabling effortless inflation and pressure checks. This design minimizes strain on valve stems during use, extending the lifespan of both the extender and original valve.
• 【Leak-Proof Sealing】Reinforced rubber gaskets and threaded sealing caps of the valve stem extenders creates a dual-layer airtight seal to prevent air loss. The internal valve core ensures controlled airflow during inflation and deflation, while the threaded connection locks securely onto standard Schrader valves. Once tightened, the system maintains consistent tire pressure even under vibration or temperature fluctuations.
• 【Durable Copper Material】Crafted from premium copper alloy, these universal metal valve extensions combine exceptional strength for prolonged durability. The copper construction ensures a secure, tight fit on valve stems, reducing the risk of stripping or damage during installation. Copper’s natural malleability allows for precise threading, enhancing airtight performance while maintaining structural integrity under pressure.
• 【Tool-Free Installation】The freely rotating threaded base of the bicycle valve stem adapter allows quick attachment by hand—simply screw onto the existing valve stem and tighten. Adjust the angle as needed, then secure the lock nut to fix the position. The included metal dust cap protects against dirt and wet, ensuring long-term reliability without requiring additional tools.
• 【Universal Compatibility】Compatible with passenger cars, motorcycles, bicycles, RVs, and trailers, these schrader valve adapters fit all standard schrader valves. Their compact size (4.1x2.6 cm) and rotatable base adapt to dual-wheel setups or narrow wheel wells, providing flexibility for vehicles with hard-to-reach valve placements.
