It is compatible with both steel and aluminum truck wheels that use a clamp-in (bolt-in) valve configuration.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat does \"clamp-in\" mean and is it different from snap-in?\u003c\/strong\u003e\u003cbr\u003eYes. 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the maximum pressure rating for the 41MS-00?\u003c\/strong\u003e\u003cbr\u003eThe 41MS-00 is rated to 150 PSI max cold pressure, which meets the requirements for most commercial truck and trailer tire applications.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat are the cross-reference part numbers for the 41MS-00?\u003c\/strong\u003e\u003cbr\u003eThe 41MS-00 is also cross-referenced as V3-20-1. If your records show V3-20-1, this is the same part.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy is the valve stem brass instead of aluminum?\u003c\/strong\u003e\u003cbr\u003eBrass 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.\u003c\/p\u003e","brand":"A2Z Tire Supplies","offers":[{"title":"1 Valve","offer_id":47546867515614,"sku":"A2Z-41MS-00-1","price":7.65,"currency_code":"USD","in_stock":true},{"title":"10 Valves","offer_id":47543127113950,"sku":"A2Z-41MS-00-10","price":30.48,"currency_code":"USD","in_stock":true},{"title":"25 Valves","offer_id":47543127146718,"sku":"A2Z-41MS-00-25","price":62.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0664\/0612\/1694\/files\/A2Z-41MS-00.jpg?v=1769334631","url":"https:\/\/a2ztiresupplies.com\/products\/41ms-00-brass-truck-valve","provider":"A2Z Tire Supplies","version":"1.0","type":"link"}
