The body and spring are both constructed from polytetrafluoroethylene (PTFE), giving the valve strong chemical resistance across a wide range of media. Rated at 120 WOG (water, oil, gas), it is suited for low- to moderate-pressure line applications. The PARFLARE x PARFLARE end connections allow for secure, leak-resistant tubing attachment consistent with Parker flare fitting standards. Licensed plumbers, HVAC technicians, and refrigeration mechanics are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis valve is designed for inline installation in 1\/2-inch pipe or tubing systems where one-directional flow must be maintained. Its all-PTFE construction makes it appropriate for corrosive fluid service, chemical lines, refrigerant circuits, and other applications where metal body valves would be unsuitable. The compact form factor allows installation in tight plumbing or mechanical system runs where space is a constraint. A Cv rating of 2.0 indicates the flow capacity through the valve under rated conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePTFE body and spring construction for broad chemical compatibility and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003ePARFLARE x PARFLARE end connections for secure, tool-compatible tubing attachment\u003c\/li\u003e\n  \u003cli\u003e120 WOG pressure rating suitable for water, oil, and gas service\u003c\/li\u003e\n  \u003cli\u003eCv rating of 2.0 for predictable flow performance\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch pipe size fits standard half-inch tubing and line configurations\u003c\/li\u003e\n  \u003cli\u003eInline design allows direct installation within existing line runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style inline check valve for 1\/2-inch PARFLARE connection systems in HVAC, refrigeration, plumbing, and chemical fluid line applications rated up to 120 WOG.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or refrigeration mechanic. Shut off and depressurize the line completely before removing any existing valve or fitting. Verify flow direction arrow or marking on the valve body before finalizing the connection. PTFE components should not be over-torqued during flare fitting assembly, as excess force can deform the sealing surfaces.\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\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: PARFLARE x PARFLARE\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\u003eCv Rating\u003c\/strong\u003e: 2.0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 120 WOG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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-1-6688\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542043328818,"sku":"CV-1-6688","price":575.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cc3130d22d77eea9e61628ce3da80c7_e925b460-21dd-4063-85fc-9013cd7bfb9b.jpg?v=1785890384","url":"https:\/\/voomisupply.com\/products\/parker-cv-1-6688-inline-check-valve-1-2-in-parflare-ptfe","provider":"Voomi Supply","version":"1.0","type":"link"}
