{"product_id":"tr501-ov-brass-truck-valve","title":"TR501-OV Brass Clamp-In Truck Valve Stem 1.5\" Oval Hole","description":"\u003cp\u003eThe TR501-OV is a 1.5\" straight brass clamp-in truck tire valve stem designed specifically for wheels with an oval valve hole measuring 0.625\" x 0.875\". Rated to 150 PSI max cold pressure, it is dimensionally identical to the standard TR501 in body diameter and thread configuration, but features an oval base flange that seals correctly against elongated valve hole geometry.\u003c\/p\u003e\u003cp\u003eIf your commercial wheel has an oval valve opening rather than a round one, the TR501-OV is the correct replacement. Using a round-base stem on an oval hole will result in an improper seal and potential air loss.\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 Oval 0.625\" x 0.875\"\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-OV\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if my wheel needs the TR501-OV versus the standard TR501?\u003c\/strong\u003e\u003cbr\u003eMeasure the valve hole in your wheel. If it is circular and approximately 0.625\" in diameter, use the TR501. If the hole is elongated (oval) and measures approximately 0.625\" x 0.875\", use the TR501-OV. Using the wrong base geometry will result in a poor seal and air leakage.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat vehicles use oval valve holes?\u003c\/strong\u003e\u003cbr\u003eOval valve holes are found on certain commercial truck and trailer wheels, particularly from some European manufacturers and older domestic designs. Check your wheel specification or measure the existing hole before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the maximum pressure rating for the TR501-OV?\u003c\/strong\u003e\u003cbr\u003eThe TR501-OV is rated to 150 PSI max cold pressure, the same as the standard TR501.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the cross-reference part numbers for the TR501-OV?\u003c\/strong\u003e\u003cbr\u003eTR501-OV is the standard industry cross-reference designation for this valve stem. Verify against your wheel spec if you are sourcing as a direct replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use the TR501-OV on a round valve hole wheel?\u003c\/strong\u003e\u003cbr\u003eNo. The oval base is designed to seal against an oval hole. Installing it on a round valve hole will not produce a proper seal. Use the standard TR501 for round 0.625\" valve holes.\u003c\/p\u003e","brand":"A2Z Tire Supplies","offers":[{"title":"1 Valve","offer_id":47546866172126,"sku":"A2Z-501-OV-1","price":7.72,"currency_code":"USD","in_stock":true},{"title":"10 Valves","offer_id":47543145857246,"sku":"A2Z-501-OV-10","price":31.23,"currency_code":"USD","in_stock":true},{"title":"25 Valves","offer_id":47543145890014,"sku":"A2Z-501-OV-25","price":64.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0664\/0612\/1694\/files\/A2Z-501-OV.jpg?v=1769334645","url":"https:\/\/a2ztiresupplies.com\/products\/tr501-ov-brass-truck-valve","provider":"A2Z Tire Supplies","version":"1.0","type":"link"}
