Metal clamp-in valve 42 MS/525 AL with short nut for tubeless passenger-car wheels

Looking for a durable valve for tubeless passenger-car wheels? Choose this nickel-plated metal clamp-in (screw-in) valve. The clamp-in design provides reliable sealing and excellent resistance to heat and high speeds. The protective polymer washer safeguards the paint/anodized finish on alloy rims and helps reduce galvanic corrosion between dissimilar metals.

Key features

• Metal, nickel-plated clamp-in valve for tubeless passenger-car wheels
• Rim hole diameter: 11.3mm (PCD standard for passenger cars)
• Overall length: 45mm — easy access on deeper seats, with trims/hubcaps
• Low-profile base for a clean look and reduced snag risk
• Tightening torque: 3–5Nm — use a calibrated torque wrench/driver
• Protective washer version — improved sealing + rim finish protection
• Complete kit: gasket (grommet), washer, nut, valve core, cap

Why a metal clamp-in valve?

Greater durability and temperature resistance than rubber valves; recommended for higher speeds, track use, higher pressures and demanding conditions. The threaded clamp-in assembly with a rubber grommet and nut ensures stable, repeatable sealing.

When is the 42mm stem useful?

When the valve seat is recessed (thicker rim bed, specific rim geometry, trims/hubcaps). The longer stem improves access for gauges, inflators and TPMS tools.

Protective washer — what's the benefit?

Prevents scratching the rim finish during tightening and provides a barrier between dissimilar metals to limit galvanic corrosion. The washer's chemical resistance and low friction help achieve even, controlled torque.

Installation notes

• Install on a clean, smooth 11.3mm valve hole
• Tighten the nut to 3–5Nm with a torque wrench/driver
• After installation, check for leaks and set the correct pressure
