Autotools Metal tyre valve 42 MS/525 AL silver

The Autotools 42 MS/525 AL is a clamp-in metal valve with a small nut for tubeless passenger car wheels on alloy rims. It is made of nickel-plated brass and has a low-profile base. A plastic protective washer keeps the valve from scratching the rim finish.

The kit holds a seal, a washer, a nut with seal, a valve core and a cap. Tighten the nut to 3-5 Nm with a torque wrench or torque screwdriver, and after fitting check for leaks and the tyre pressure.
