Rated at 400 WOG (Water-Oil-Gas), it carries a crack pressure of 0.50 psi and a maximum operating temperature of 550 degrees F, making it suitable for a wide range of commercial and industrial service conditions. The body and seat are both bronze, meeting ASTM B61 material standards and conforming to MSS SP-80. Licensed plumbers and pipefitters are the primary installers of this type of valve in hydronic, fuel, and utility piping systems.\u003c\/p\u003e\u003cp\u003eThis check valve is sized for 3\/8 inch pipe and is well suited for residential and light commercial plumbing, HVAC hydronic loops, gas distribution lines, and oil supply piping. Its threaded NPT connections make it compatible with standard pipe and fitting systems without the need for specialized tooling. The operating temperature range of -20 degrees F to 550 degrees F covers most conventional service environments where backflow prevention is required at low crack pressure.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e400 WOG pressure rating for use with water, oil, and gas service\u003c\/li\u003e\n\u003cli\u003eLow crack pressure of 0.50 psi allows the valve to open under minimal differential pressure\u003c\/li\u003e\n\u003cli\u003eBronze body and seal construction rated to ASTM B61 material grade\u003c\/li\u003e\n\u003cli\u003eThreaded NPT end connections for straightforward installation into standard pipe systems\u003c\/li\u003e\n\u003cli\u003eConforms to MSS SP-80 industry standards for bronze valves\u003c\/li\u003e\n\u003cli\u003eWide temperature range: -20 degrees F to 550 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with gas, oil, and water piping systems.

Shut off and depressurize the line completely before removing or installing any check valve. Verify correct flow direction before threading the valve into place, as check valves are directional and will not function properly if installed backwards. Use appropriate thread sealant rated for the service fluid — confirm compatibility with gas or oil service before application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: NPT (Threaded)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 400 WOG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrack Pressure\u003c\/strong\u003e: 0.50 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Pressure\u003c\/strong\u003e: 5 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 550 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -20 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: ASTM B61\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: MSS SP-80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.54 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MILWAUKEE VALVE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 508-38\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE VALVE","offers":[{"title":"Default Title","offer_id":51713231814962,"sku":"508-38","price":122.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/832aac30ed7aa572ec9e603f9ca10030_c0be8803-7332-473f-83d2-06ee7650de50.jpg?v=1788492159","url":"https:\/\/voomisupply.com\/products\/milwaukee-valve-508-38-bronze-check-valve-3-8-inch-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
