Built with a stainless steel body and stainless steel spring, it is rated for a maximum working pressure of 6000 psi and a crack pressure of 1.00 psi. The FNPT x FNPT end connections make it straightforward to install in existing threaded piping runs. This valve is typically installed by licensed plumbers, pipefitters, or mechanical contractors working on hydraulic lines, instrumentation systems, compressed gas circuits, or other high-pressure process piping applications.\u003c\/p\u003e\n\u003cp\u003eThis check valve is suited for inline installation in residential, commercial, and industrial piping systems where backflow prevention is required. The 1\/4 inch pipe size fits compact instrumentation and control lines as well as hydraulic and pneumatic circuits. Its stainless steel construction makes it appropriate for corrosive media, high-cycle service, and environments where carbon steel or brass fittings are not acceptable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum working pressure of 6000 psi for demanding high-pressure applications\u003c\/li\u003e\n  \u003cli\u003eCrack pressure of 1.00 psi allows the valve to open at minimal differential pressure\u003c\/li\u003e\n  \u003cli\u003eStainless steel body and spring for corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT end connections for direct threaded installation\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch pipe size suits instrumentation, hydraulic, and pneumatic lines\u003c\/li\u003e\n  \u003cli\u003eInline design for easy integration into existing piping runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install inline check valve for 1\/4 inch FNPT threaded piping systems rated to 6000 psi working pressure.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or qualified mechanical technician familiar with high-pressure piping systems. Depressurize and isolate the line completely before removing any existing valve or fitting. Apply appropriate thread sealant compatible with the system media to all FNPT connections. Verify that flow direction aligns with the valve orientation before pressurizing the system.\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: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrack Pressure\u003c\/strong\u003e: 1.00 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 6000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4F-C4L-1-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538247450930,"sku":"4F-C4L-1-SS","price":146.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/942566d67c91a005c45d00d3b114ba4f.jpg?v=1785820729","url":"https:\/\/voomisupply.com\/products\/parker-4f-c4l-1-ss-check-valve-1-4-in-fnpt-ss-6000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
