Built with an aluminum body, this valve is sized for 0.25-inch pipe with female NPT connections on both ends. At just 0.05 pounds, it is suited for light-duty installations where a small, reliable check valve is needed. A minimum operating pressure of 4 psi is required to open the valve. Plumbers, pipefitters, and HVAC technicians commonly install this type of component in compressed air lines, fluid transfer systems, and similar low-volume piping circuits.\u003c\/p\u003e\n\u003cp\u003eThis check valve is intended for inline installation in 0.25-inch pipe systems using standard NPT threaded connections. Its compact dimensions make it a practical choice for tight spaces in residential and light commercial applications. The FNPT x FNPT end configuration threads directly into existing pipe runs without additional adapters in most standard installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInline check valve prevents backflow in 0.25-inch pipe systems\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT end connections for direct thread-in installation\u003c\/li\u003e\n  \u003cli\u003eAluminum body construction for lightweight service\u003c\/li\u003e\n  \u003cli\u003eMinimum opening pressure of 4 psi\u003c\/li\u003e\n  \u003cli\u003eCompact profile at 1.97 inches long and 0.67 inches in height and width\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.05 pounds for easy handling in confined spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for inline 0.25-inch NPT piping systems in residential and light commercial fluid or pneumatic applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the system completely before threading in or removing any check valve. Apply appropriate thread sealant or PTFE tape to NPT threads per local plumbing code requirements. Confirm flow direction arrow or inlet and outlet orientation before making final connections.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Inline Check Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Pressure\u003c\/strong\u003e: 4 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.97 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.67 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.67 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: PRO-SOURCE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4926801813PRO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51740940140850,"sku":"4926801813PRO","price":23.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d09e40c8683394ae5074d220a5a23291.jpg?v=1788828492","url":"https:\/\/voomisupply.com\/products\/pro-source-4926801813pro-check-valve-1-4-inch-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
