The body is constructed from brass with a stainless steel spring, making it suitable for use in water, oil, and gas service lines rated up to 3,000 WOG (Water, Oil, Gas). It uses compression x compression end connections, which allow tool-assisted installation without soldering or threading. This valve is a common choice for licensed plumbers and HVAC technicians working on fluid control applications where backflow prevention is required.\u003c\/p\u003e\u003cp\u003eThis inline check valve is suited for residential and light commercial plumbing and HVAC systems. The 3\/4 inch compression x compression configuration makes it compatible with standard copper or compatible tubing installations. It is typically installed in supply lines, heating loops, or other pressurized fluid circuits where reverse flow could cause system damage or inefficiency. The compact inline design allows installation in tight spaces with minimal line modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInline check valve design prevents backflow in pressurized fluid lines\u003c\/li\u003e\n\u003cli\u003eBrass body provides corrosion resistance for water, oil, and gas service\u003c\/li\u003e\n\u003cli\u003eStainless steel spring ensures reliable valve seating and long service life\u003c\/li\u003e\n\u003cli\u003eCompression x compression end connections eliminate the need for soldering or threading\u003c\/li\u003e\n\u003cli\u003e3,000 WOG pressure rating suitable for demanding plumbing and HVAC applications\u003c\/li\u003e\n\u003cli\u003e3\/4 inch pipe size fits standard residential and light commercial line sizes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style inline check valve for residential and light commercial plumbing and HVAC systems using 3\/4 inch compression fittings.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local codes and the IPC. Shut off the water supply and relieve system pressure completely before removing any existing fittings or valves. Ensure the valve is oriented in the correct flow direction as indicated by the arrow or marking on the valve body. Do not overtighten compression fittings, as this can deform the ferrule and cause leaks.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Compression x Compression\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Inline Check Valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 3,000 WOG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 12Z-C12L-1-BN-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51543456121138,"sku":"12Z-C12L-1-BN-B","price":412.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8691110676a06e711f6f0ac3efbf6ffb_648882c1-b965-433b-afe2-6d9245458b98.jpg?v=1785918881","url":"https:\/\/voomisupply.com\/products\/parker-12z-c12l-1-bn-b-check-valve-3-4-in-compression","provider":"Voomi Supply","version":"1.0","type":"link"}
