Product Specification:

The product offers three different angles for valve stem extensions: 2 x 45 degree, 2 x 90 degree, and 2 x 135 degree.

The 45-degree extension has a long side of 1.4 inch/3.5 cm and a short side of 1 inch/2.5 cm. The 90-degree extension has a long side of 1.4 inch/3.5 cm and a short side of 1 inch/2.5 cm. The 135-degree extension has a long side of 1.6 inch/4 cm and a short side of 0.9 inch/2.2 cm.

Warning:

Before driving, it is recommended to remove the Schrader valve extension from the tire. The design of the stem extension is not suitable for wheels in high-speed operation. High-speed rotation and vibration may cause loosening and air leakage risks.

For your safety and user experience, be sure to tighten the threads on the valve core, and the cap on the valve core also needs to be tightened before it can exert its airtight effect.

The three valve stem extensions (45 degree, 90 degree, and 135 degree) successfully solved a series of operations, such as the inability to pump or check air pressure due to insufficient space between the valve and the spokes, or the inconvenient position and angle of the valve. Due to the built-in valve core, they can allow inflation and deflation, which is convenient and quick.

Be sure to tighten the thread when using it; otherwise, the best sealing effect cannot be achieved.

The tire valve extension joint is made of brass, with a chrome-plated surface. The chrome-plated layer has higher hardness, better heat resistance, and is not easy to rust. Equipped with a rubber sealing ring and sealing cover, it is durable.

Prevent Air Leakage: 1. Install the valve angle extension on the valve core, and be sure to tighten the thread of the rotating part so that there is no air leakage. 2. When adjusting the angle, rotate the valve extension. After the angle adjustment is over, you must tighten the rotating thread to the maximum. 3. The threaded head on the valve extenders is screwed on the existing valve stem, and the included end cap replaces the existing valve stem cover.

Our valve core adapters are equipped with rubber sealing rings and sealing caps to ensure airtightness without leakage. It is recommended to tighten the sealing caps quickly after use to prevent air leakage.

These tire valve extensions are suitable for most bicycles, motorcycles, strollers, trailers, and RVs with standard American tire valves.
