Truck Valve 50MS TPMS – TA03 ALU

Clamp-in valve for TPMS sensors in commercial vehicles

The straight 50MS truck valve is designed for wheels of vehicles equipped with a direct tire pressure monitoring system (TPMS). It is suitable for trucks, buses, trailers, and semi-trailers where a durable, airtight, and operationally resistant connection between the valve, rim, and TPMS sensor is required.

The valve is designed for rims with a valve hole diameter of 9.7 mm (+0.3 mm). Unlike angled versions, the 50MS model features a straight valve stem, allowing installation in rims where no offset of the valve end is required.

Brass construction with nickel coating

The valve body is made of brass and coated with a nickel layer. The nickel-plated surface increases resistance to corrosion, moisture, and operating contamination, while also protecting the contact area between the valve and the rim. This is particularly important in commercial vehicles operating under variable road conditions and heavy loads.

Clamp-in design

The 50MS valve features a clamp-in construction. The valve stem is inserted through the rim hole and then mechanically secured using a nut and sealing components.

30° sensor mounting angle

The sensor-side base of the valve is specially shaped so that the TPMS sensor mounting screw is guided at a 30° angle. This positioning allows correct alignment of the sensor in relation to the valve and the inside of the rim.

The TPMS sensor is mounted using an M6 Torx TX20 screw with washer. The valve is compatible with the CUB TPMS Truck 2.0 Uni-Sensor. It may also be compatible with other TPMS sensors mounted in the same way (e.g. Hamaton EU-PRO Truck 1.0), provided they meet the structural requirements of the valve and rim.

Valve components

The valve set includes:

• straight valve stem,
• valve nut for size 16 wrench,
• rubber seals,
• valve insert,
• metal cap with seal,
• M6 Torx TX20 screw with washer for TPMS sensor mounting.

Application

The 50MS valve is designed for installation in truck rims equipped with direct TPMS systems. It can be used when replacing a damaged valve, installing a new TPMS sensor, or preparing an additional wheel set – as a replacement for valves such as:

• Hamaton 6-461
• Alcoa 45MS
• Wonder 1353
• Wonder 1313

Thanks to its metal construction, nickel-plated surface, straight valve stem, and clamp-in mounting design, the valve provides durable installation, reliable sealing, and high resistance to operating conditions typical for commercial vehicles.
