The body is constructed from glass fiber reinforced nylon, making it lightweight and resistant to corrosion in both water and light chemical service applications. The valve features a combination thread profile that accepts both NPT and BSP connections, and its spring-loaded mechanism allows installation at any angle without requiring a specific orientation. Low lead compliance makes it suitable for potable water installations where lead content restrictions apply. A nitrile rubber O-ring provides a reliable seal, and the valve is fully serviceable in the field.\u003c\/p\u003e\n\u003cp\u003eThis check valve is suited for residential and light commercial plumbing, hydronic heating systems, and water treatment installations where backflow prevention is required on a 1-1\/4-inch line. The combination NPT and BSP thread compatibility makes it a practical choice in mixed-thread piping environments or retrofit situations. Its serviceable, reusable design reduces replacement costs over time, and the non-corrosive nylon body handles wet service conditions without degradation. Licensed plumbers and HVAC technicians install this type of valve on domestic water, glycol, and similar fluid systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGlass fiber reinforced nylon body resists corrosion in wet service applications\u003c\/li\u003e\n  \u003cli\u003eSpring-loaded design allows installation at any angle, including vertical downflow\u003c\/li\u003e\n  \u003cli\u003eCombination thread accepts both NPT and BSP pipe connections\u003c\/li\u003e\n  \u003cli\u003eLow lead compliant for use in potable water systems\u003c\/li\u003e\n  \u003cli\u003eFully serviceable and field-disassembled without replacing the valve body\u003c\/li\u003e\n  \u003cli\u003eNitrile rubber O-ring provides a durable, reliable seal\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 1-1\/4-inch FNPT plumbing and hydronic piping systems requiring backflow prevention and low lead compliance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with the applicable local plumbing code and IPC guidelines. Shut off the water supply and relieve system pressure before removing or installing the valve. Thread sealant compatible with the pipe material and fluid type should be applied to male threads before making connections. Do not overtighten threaded connections into the nylon body, as excessive torque can crack the fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Compatibility\u003c\/strong\u003e: NPT and BSP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Glass Fiber Reinforced Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Nitrile Rubber O-ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLow Lead Compliant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 27 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50\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: WATTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ACV114\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":51525248844082,"sku":"ACV114","price":1073.93,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4187694ca12a7a034f544f8551a66922.jpg?v=1785468375","url":"https:\/\/voomisupply.com\/products\/watts-acv114-check-valve-1-1-4-inches-fnpt-low-lead","provider":"Voomi Supply","version":"1.0","type":"link"}
