Tyre Valves - Pack Of 10 - Clamp-In Safety Hump 45 Degree - 9.7mm

The safety hump helps to securely seat the valve in the rim hole, preventing it from being pulled back into the tire during inflation or under high pressure, thus ensuring a more reliable seal.

Yes, these metal clamp-in valves are generally suitable for alloy wheels, provided the rim has the correct 9.7mm valve hole size. Always consult your wheel manufacturer's specifications if unsure.

The 45-degree angle makes it easier to connect an air hose or tire pressure gauge to the valve stem, especially on wheels where the stem is positioned in a tight spot.

The installation torque of 13-15 Nm is critical. Too little torque may result in an air leak, while too much torque can damage the valve or the wheel rim.

Yes, clamp-in metal tyre valves with a safety hump are designed for use with tubeless tires.

Metal valves are generally more durable than rubber ones. With proper care and installation, they can last for many years, but regular inspection for damage or corrosion is recommended.

You will need tools to remove the old valve and, crucially, a torque wrench to ensure the new valve is installed at the specified 13-15 Nm. Tire mounting equipment is also typically required.

Check that the valve is tightened to the correct torque (13-15 Nm). Ensure the valve base is properly seated against the rim and that there are no visible cracks or damage to the valve stem. Inspect the valve core for tightness.

Confirm that the rim hole is indeed 9.7mm. Ensure the valve stem is inserted straight into the hole. Lubricating the rubber base slightly might help, but avoid excessive force. Professional installation may be required if issues persist.

Replace the valve immediately. Metal valves can corrode over time, especially in harsh environments. Damaged valves compromise tire pressure and safety.
