The 70MS-7 Clamp-In Metal Valve Stem is a heavy-duty, commercial-grade tire valve designed specifically for medium and heavy-duty trucks, buses, and commercial trailers utilizing aluminum or steel wheels. Engineered for high-pressure reliability and long-haul durability, it is a preferred standard choice for Alcoa-style wheel assemblies requiring a precise, leak-proof seal.
