Built with a polytetrafluoroethylene (PTFE) body and PTFE spring, this valve delivers strong chemical resistance across a wide range of media. It connects via female NPT (FNPT) threads on both ends and is rated for 120 WOG (Water, Oil, Gas) service. The 3\/8 inch pipe size and compact form factor make it a practical choice for tight plumbing runs. Licensed plumbers, HVAC technicians, and industrial piping contractors are the typical installers of this fitting.\u003c\/p\u003e\n\u003cp\u003eThis check valve is suited for residential and light commercial plumbing, HVAC hydronic systems, chemical handling lines, and compressed air or gas distribution where backflow prevention is required. The PTFE construction makes it appropriate for corrosive or high-purity fluid applications where metal-bodied valves would be unsuitable. Its inline configuration allows direct installation into existing 3\/8 inch NPT threaded pipe runs without additional fittings or adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePTFE body and spring construction for broad chemical compatibility\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT end connections for direct threaded installation\u003c\/li\u003e\n  \u003cli\u003eInline flow path simplifies integration into existing pipe runs\u003c\/li\u003e\n  \u003cli\u003e120 WOG pressure rating for water, oil, and gas service\u003c\/li\u003e\n  \u003cli\u003eCv rating of 2.430 supports adequate flow capacity for 3\/8 inch lines\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for use in space-restricted installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation check valve for 3\/8 inch FNPT threaded piping systems rated for 120 WOG service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified technician. Shut off and depressurize the system completely before removing any existing valve or fitting. Apply appropriate thread sealant to NPT connections per local plumbing code requirements. Verify flow direction marking on the valve body before finalizing installation to ensure backflow prevention functions as intended.\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\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 120 WOG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCv Rating\u003c\/strong\u003e: 2.430\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Material\u003c\/strong\u003e: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: CV-1-1166\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542486483250,"sku":"CV-1-1166","price":600.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cc3130d22d77eea9e61628ce3da80c7_70359ae5-b0b6-4289-887f-4d5be617b05e.jpg?v=1785901648","url":"https:\/\/voomisupply.com\/products\/parker-cv-1-1166-check-valve-3-8-inch-fnpt-inline","provider":"Voomi Supply","version":"1.0","type":"link"}
