The body is constructed from polypropylene, offering resistance to a wide range of chemicals and moisture. This valve has a crack pressure of 3.00 psi and is rated for a minimum operating pressure of 0 psi, making it suitable for low-pressure applications. At 0.5 pounds, it is a compact, lightweight component installed by HVAC technicians, plumbers, and fluid system specialists in both equipment assembly and field service work.\u003c\/p\u003e\u003cp\u003eThis check valve is suited for inline installation in tubing systems where backflow prevention is required. The barb connection style is compatible with tubing that has a 5\/32 inch inside diameter, with an outside diameter measuring approximately 16.30 millimeters. Typical applications include pneumatic control lines, condensate drainage systems, fluid transfer assemblies, and similar low-to-moderate pressure circuits found in residential and light commercial equipment. It is packaged and sold as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInline check valve design prevents reverse flow without manual actuation\u003c\/li\u003e\n\u003cli\u003eBarb connection type provides a secure friction fit on compatible tubing\u003c\/li\u003e\n\u003cli\u003ePolypropylene body offers corrosion resistance and chemical compatibility\u003c\/li\u003e\n\u003cli\u003eLow crack pressure of 3.00 psi allows actuation under minimal differential pressure\u003c\/li\u003e\n\u003cli\u003eRated for a minimum operating pressure of 0 psi, suitable for gravity-assist or near-atmospheric circuits\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.5 pounds for easy handling and installation in tight spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with tubing having a 5\/32 inch inside diameter and a barb-style connection.

Before servicing, shut off all pressure supply to the line and verify pressure has fully relieved before disconnecting tubing. Ensure tubing inside diameter matches the barb fitting dimension to maintain a proper seal and prevent leakage. Follow all applicable plumbing and mechanical codes for the jurisdiction and system type in which this valve is installed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Inline Check Valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Barb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrack Pressure\u003c\/strong\u003e: 3.00 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Operating Pressure\u003c\/strong\u003e: 0 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Inside Diameter\u003c\/strong\u003e: 5\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 16.30 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORGREN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4LD-064-D00\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORGREN","offers":[{"title":"Default Title","offer_id":51692498714930,"sku":"4LD-064-D00","price":74.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96a98878bbb7e2ce06441a794014126f.jpg?v=1788298486","url":"https:\/\/voomisupply.com\/products\/norgren-4ld-064-d00-inline-barb-check-valve-5-32-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
