Constructed from brass, it delivers reliable sealing and resists corrosion in shop and field environments. The closed-check design holds air in the line when the chuck is disconnected, reducing pressure loss and keeping the system primed. The 1\/4-inch FPT threaded connection fits standard air hose fittings and inflator whips. Built for heavy-duty use, this chuck is suited to daily demands in automotive, fleet, and industrial settings where consistent, fast tire service is required.\u003c\/p\u003e\n\u003cp\u003eThe CH15 is intended for non-gauged inflation applications where a reliable lock-on connection is needed to seat and hold the chuck on a valve stem without continuous hand pressure. Typical install scenarios include tire service bays, fleet maintenance shops, and mobile service rigs. The lock-on design frees the technician to monitor inflation while the chuck remains secured to the valve stem, improving workflow and reducing the chance of accidental disconnection during inflation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClosed-check design retains line pressure when chuck is disconnected\u003c\/li\u003e\n  \u003cli\u003eLock-on chuck style holds securely to valve stem without hand pressure\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance and long service life\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch FPT thread for compatibility with standard air hose assemblies\u003c\/li\u003e\n  \u003cli\u003eRated for heavy-duty use in automotive, fleet, and industrial service\u003c\/li\u003e\n  \u003cli\u003eDesigned for non-gauged tire inflation applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or add-on lock-on air chuck for standard pneumatic inflator whips and air hose assemblies with 1\/4-inch FPT connections used in non-gauged tire inflation service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a pneumatic technician or tire service professional. Depressurize the air line before threading the CH15 onto the inflator whip or hose end fitting. Apply thread sealant tape to the 1\/4-inch FPT threads to prevent air leakage at the connection. Inspect the chuck and check valve for wear or debris before returning the assembly to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChuck Type\u003c\/strong\u003e: Lock-On\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\u003eThread Standard\u003c\/strong\u003e: FPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\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: 0.09 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40142200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: CH15\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COILHOSE PNEUMATICS","offers":[{"title":"Default Title","offer_id":51557951504690,"sku":"CH15","price":27.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/301518522ce7e9247c4e8abc2bafffc7.jpg?v=1786399301","url":"https:\/\/voomisupply.com\/products\/coilhose-pneumatics-ch15-closed-check-brass-air-chuck","provider":"Voomi Supply","version":"1.0","type":"link"}
