At 1.5\" in height with a 0.625\" valve hole and 150 PSI max cold pressure rating, it is the standard go-to for commercial trucks, buses, trailers, and most heavy equipment wheel applications.\u003c\/p\u003e\u003cp\u003eBuilt with a solid brass body and O-ring seal, the TR501 provides a secure, leak-free mount that holds up under the continuous vibration, pressure cycling, and environmental exposure of commercial vehicle operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 1.5\" straight profile\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Hole:\u003c\/strong\u003e 0.625\" standard truck wheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Cold Pressure:\u003c\/strong\u003e 150 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Brass body with O-ring seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-Reference:\u003c\/strong\u003e TR501\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the TR501 compatible with all commercial truck wheels?\u003c\/strong\u003e\u003cbr\u003eThe TR501 fits any commercial wheel with a standard 0.625\" round valve hole using a clamp-in configuration. This covers the vast majority of commercial truck, bus, and trailer wheels. If your wheel has an oval valve hole, see the TR501-OV. If your wheel uses the smaller 0.382\" valve hole, see the MS series stems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between the TR501 and TR500?\u003c\/strong\u003e\u003cbr\u003eThe TR501 is 1.5\" tall; the TR500 is 2\" tall. Both are straight brass clamp-in stems for 0.625\" holes at 150 PSI. The TR501 is the standard choice for most wheels; use the TR500 when extra height is needed for wheel cover or valve pocket clearance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the maximum pressure rating for the TR501?\u003c\/strong\u003e\u003cbr\u003eThe TR501 is rated to 150 PSI max cold pressure for commercial truck and trailer tire applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the cross-reference part numbers for the TR501?\u003c\/strong\u003e\u003cbr\u003eTR501 is the industry-standard part designation, recognized universally across commercial tire suppliers, OEM documentation, and fleet maintenance records.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need a special tool to install the TR501?\u003c\/strong\u003e\u003cbr\u003eYes, proper installation requires a clamp-in valve installation tool and the correct torque on the retaining nut, typically around 4 in-lb. Overtightening can crack the brass body; undertightening can allow air leakage. A valve core tool is also needed to install the valve core after mounting.\u003c\/p\u003e","brand":"A2Z Tire Supplies","offers":[{"title":"1 Valve","offer_id":47546866434270,"sku":"A2Z-501-1","price":7.65,"currency_code":"USD","in_stock":true},{"title":"10 Valves","offer_id":47543144349918,"sku":"A2Z-501-10","price":30.48,"currency_code":"USD","in_stock":true},{"title":"25 Valves","offer_id":47543144382686,"sku":"A2Z-501-25","price":62.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0664\/0612\/1694\/files\/A2Z-501.jpg?v=1769334644","url":"https:\/\/a2ztiresupplies.com\/products\/tr501-brass-truck-valve","provider":"A2Z Tire Supplies","version":"1.0","type":"link"}
