It uses a male pipe thread on both ends (MPT x MPT) and is rated to 500 psi working pressure with a maximum temperature of 180 degrees F. The valve body is machined from brass and seals with a FKM (Viton-compatible) elastomer, making it suitable for a range of fluids including petroleum-based media. A cracking pressure of 1 psi means the valve opens with minimal upstream pressure, keeping flow resistance low. Licensed plumbers and pipefitters are the typical installers for this fitting class.\u003c\/p\u003e\n\u003cp\u003eThis check valve suits residential and light commercial plumbing systems where backflow prevention is required on smaller-diameter lines. The 3\/8 inch MPT x MPT configuration fits standard threaded pipe runs and is commonly installed in water supply, compressed air, or fuel lines. Its compact brass body and FKM seal make it well suited for applications that demand chemical resistance and durability in tight spaces. The domestic designation indicates U.S. manufacture, which is relevant for projects with domestic-content requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e500 psi maximum working pressure for high-demand plumbing and fluid system use\u003c\/li\u003e\n  \u003cli\u003eFKM (Viton-compatible) seal provides resistance to petroleum-based fluids and elevated temperatures\u003c\/li\u003e\n  \u003cli\u003e1 psi cracking pressure minimizes flow restriction at low upstream pressure\u003c\/li\u003e\n  \u003cli\u003eBrass body construction offers corrosion resistance in water and fuel service\u003c\/li\u003e\n  \u003cli\u003eMPT x MPT connection on both ends simplifies installation into existing threaded runs\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured for projects with U.S.-origin requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install check valve for 3\/8 inch threaded pipe systems in residential and light commercial plumbing, compressed air, and fuel line applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or pipefitter. Shut off the supply line and relieve system pressure fully before removing any existing valve or fitting. Apply thread sealant tape or compound rated for the intended media to the male threads before making up the joint. Verify flow direction against the arrow or markings on the valve body before completing the installation, and pressure-test the assembly before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MPT x MPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 500 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 180 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCracking Pressure\u003c\/strong\u003e: 1 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: FKM (Viton-compatible)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic (USA)\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: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 46572V\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67948570280242,"sku":"46572V","price":35.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a613cf48a28ee89c6f698b48b6aee3c0.jpg?v=1791667618","url":"https:\/\/voomisupply.com\/products\/midland-industries-46572v-brass-check-valve-3-8-in-mpt","provider":"Voomi Supply","version":"1.0","type":"link"}
