Built with a stainless steel body and stainless steel spring, it handles maximum working pressures up to 6000 psi with a crack pressure of 1.00 psi. The valve connects via male NPT fittings on both ends at a 3\/8 inch pipe size, making it straightforward to integrate into existing threaded line assemblies. It is well suited for industrial, hydraulic, and process piping applications where corrosion resistance and pressure integrity are critical requirements. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis check valve is intended for inline installation in systems requiring reliable backflow prevention under high-pressure conditions. Its stainless steel construction makes it appropriate for corrosive media, washdown environments, and applications where carbon steel components would degrade. The MNPT x MNPT end connections fit standard 3\/8 inch threaded pipe runs common in hydraulic circuits, pneumatic lines, chemical processing, and HVAC refrigerant or water-side piping. The compact, single-piece body design minimizes installation space requirements while maintaining full-rated working pressure.\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\u003eLow crack pressure of 1.00 psi allows flow with minimal system pressure drop\u003c\/li\u003e\n  \u003cli\u003eStainless steel body and spring provide corrosion resistance in aggressive environments\u003c\/li\u003e\n  \u003cli\u003eMNPT x MNPT connections on both ends for straightforward threaded pipe installation\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch pipe size fits standard trade piping configurations\u003c\/li\u003e\n  \u003cli\u003eCompact inline design suited for space-constrained plumbing and hydraulic assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style inline check valve replacement for 3\/8 inch MNPT threaded pipe systems rated to high-pressure service.

Depressurize and isolate the system fully before removing any existing valve or fitting. Apply appropriate thread sealant to the MNPT connections and avoid over-tightening, which can crack fittings or distort sealing surfaces. Confirm the flow direction arrow or valve orientation matches system flow before pressurizing the line.\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: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MNPT x MNPT\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: 0.5 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: 6M-C6L-1-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541714829618,"sku":"6M-C6L-1-SS","price":312.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87f9de5a8e99f94b47413ae4b0b3de97_48457091-c8c7-4b03-936f-d9aa286ad483.jpg?v=1785882825","url":"https:\/\/voomisupply.com\/products\/parker-6m-c6l-1-ss-inline-check-valve-3-8-in-mnpt-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
