    Frequently Asked Questions

    What vehicles and wheel types is the 41MS-00 compatible with?
    The 41MS-00 is designed for commercial trucks, semi-trailers, box trucks, and heavy equipment wheels with a standard 0.382" valve hole. It is compatible with both steel and aluminum truck wheels that use a clamp-in (bolt-in) valve configuration.

    What does "clamp-in" mean and is it different from snap-in?
    Yes. A clamp-in (also called bolt-in) valve stem is secured to the wheel with a nut on the inside, making it a permanent, high-pressure-rated mount. Snap-in rubber stems are pressed in by hand and are typically limited to passenger car pressures. Clamp-in is the standard for commercial truck and trailer applications.

    What is the maximum pressure rating for the 41MS-00?
    The 41MS-00 is rated to 150 PSI max cold pressure, which meets the requirements for most commercial truck and trailer tire applications.

    What are the cross-reference part numbers for the 41MS-00?
    The 41MS-00 is also cross-referenced as V3-20-1. If your records show V3-20-1, this is the same part.

    Why is the valve stem brass instead of aluminum?
    Brass offers excellent corrosion resistance, machinability, and durability under the high-pressure, high-vibration conditions of commercial trucking. It resists oxidation better than steel and handles the thermal cycling of truck tires reliably over time.
