With a 90-degree angle and a length of 30 mm, it is ideal for rims with a valve hole of 8.3 mm. The valve is made from durable rubber and tested to withstand tire pressures up to 4.5 bar, ensuring a safe and reliable seal. ### Suitable for various applications This valve is perfect for standard scooters and light motorcycles. It is designed for easy installation and provides a reliable seal, which is essential for maintaining the correct tire pressure and ensuring a safe ride. ### Importance of choosing the right valve Choosing the right valve is crucial for the safety and performance of your vehicle. For heavily loaded vehicles such as vans and trailers, where tire pressure can be significantly higher, the use of steel valves is recommended. These can withstand higher pressures and offer extra safety. ### Various sizes available Sinatec offers a range of rubber tubeless valves in different lengths: 33 mm, 43 mm, 49 mm, and 61 mm. It is important to always use the length recommended by the car or rim manufacturer. Longer valves can be subjected to extra stress from centrifugal forces, increasing the risk of leakage. ### Specifications - **Brand:** Sinatec Unimotive - **Type:** Tubeless valve - **Angle:** 90 degrees - **Length:** 30 mm - **Valve hole diameter:** 8.3 mm - **Maximum tire pressure:** 4.5 bar - **Material:** Durable rubber ### Benefits - Easy installation - Reliable seal - Suitable for standard scooters and light motorcycles - Tested for durability and safety ### Application advice For vehicles with a tire pressure above 4.5 bar, such as heavily loaded vans and trailers, the use of steel valves is recommended.

Replace worn or damaged valves in time to ensure the safety and performance of your vehicle. ## Breadcrumbs - [Luggage & Transport](https://www.auto-service.be/en/luggage-transport) - [Tire Material](https://www.auto-service.be/en/luggage-transport/tire-material) -
