It connects to air hoses via a 1\/4-inch barbed fitting and is designed for non-gauged tire inflation in shop and field service applications. The closed-check valve design prevents air loss when the chuck is disengaged from the valve stem, allowing a cleaner, more controlled inflation process. Built for heavy-duty use, the brass body resists corrosion and wear, supporting a long service life in demanding environments. Automotive technicians, fleet mechanics, and tire service professionals use this chuck as a reliable daily-use inflation tool.\u003c\/p\u003e\u003cp\u003eThis chuck is suited for tire service bays, fleet maintenance shops, and roadside service operations where fast, repeatable connections to Schrader valve stems are required. The ball foot design allows the chuck to lock onto the valve stem at an angle, which is especially useful when working around wheel weights, tight spoke clearances, or low-profile wheels. It performs best in non-gauged inflation setups where a separate in-line gauge or tank-mounted gauge is already part of the air supply system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClosed-check valve prevents air bleed-back when chuck is removed from the valve stem\u003c\/li\u003e\n\u003cli\u003eBall foot chuck style locks onto valve stems at an angle for easy access in tight clearances\u003c\/li\u003e\n\u003cli\u003e1\/4-inch barbed inlet fits directly onto standard air hose ends\u003c\/li\u003e\n\u003cli\u003eBrass construction provides corrosion resistance and durability in heavy-duty shop use\u003c\/li\u003e\n\u003cli\u003eDesigned for non-gauged tire inflation applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit chuck for standard Schrader valve tire inflation setups using non-gauged air supply lines with 1\/4-inch barbed hose connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by pressing the barbed fitting firmly into a compatible 1\/4-inch air hose end or pushing it through a hose barb clamp assembly. Depressurize the air line before connecting or disconnecting the chuck from the hose. No special tools are required for hose attachment, but a hose clamp driver may be used if a clamp is applied over the barb. Verify that the air supply pressure does not exceed the rated capacity of the hose and associated fittings in the inflation system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChuck Type\u003c\/strong\u003e: Ball Foot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCheck Type\u003c\/strong\u003e: Closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection\u003c\/strong\u003e: 1\/4 inch Barbed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Non-gauged tire inflation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40142200\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: COILHOSE PNEUMATICS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CH12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COILHOSE PNEUMATICS","offers":[{"title":"Default Title","offer_id":51561640984882,"sku":"CH12","price":15.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/298ee4ea1c1b52b73f83640172cd9cb8.jpg?v=1786466953","url":"https:\/\/voomisupply.com\/products\/coilhose-pneumatics-ch12-closed-check-ball-foot-brass-air-chuck","provider":"Voomi Supply","version":"1.0","type":"link"}
