Built with a stainless steel body and stainless steel spring, it handles working pressures up to 6000 psi, making it well suited for demanding industrial and mechanical applications. The 1\/4 inch MNPT x MNPT end connections allow direct threaded installation into standard pipe fittings. At 0.2 pounds, it is compact and lightweight. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers for this type of component.\u003c\/p\u003e\u003cp\u003eThis check valve is intended for inline installation in hydraulic, pneumatic, instrumentation, or process piping lines where backflow prevention is required. The 1\/4 inch pipe size and MNPT x MNPT configuration make it a common choice for small-bore lines in both commercial and industrial settings. A crack pressure of 1.00 psi allows the valve to open under minimal differential pressure, which is appropriate for low-resistance flow applications. It is commonly found in compressed air systems, fluid control panels, and instrumentation tubing assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStainless steel body and spring construction for corrosion resistance in harsh environments\u003c\/li\u003e\n\u003cli\u003eMaximum working pressure of 6000 psi for high-pressure system compatibility\u003c\/li\u003e\n\u003cli\u003eLow crack pressure of 1.00 psi enables reliable opening under minimal flow pressure\u003c\/li\u003e\n\u003cli\u003e1\/4 inch MNPT x MNPT end connections for straightforward threaded pipe installation\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.2 pounds for use in tight installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style inline check valve for 1\/4 inch MNPT threaded piping systems in industrial, hydraulic, pneumatic, and instrumentation applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or qualified mechanical technician. Depressurize and isolate the system completely before removing any existing fittings or installing this valve. Apply appropriate thread sealant to the MNPT connections per the system fluid compatibility requirements, and verify that the valve is oriented in the correct flow direction before pressurizing the system. Follow applicable codes including ASME and local mechanical codes for high-pressure piping installations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Inline Check Valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MNPT x MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/4 inch\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: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 4M-C4L-1-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541841379634,"sku":"4M-C4L-1-SS","price":142.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5ed613b2711d789124e7c82147b8fda.jpg?v=1785886546","url":"https:\/\/voomisupply.com\/products\/parker-4m-c4l-1-ss-inline-check-valve-1-4-in-mnpt-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
