It features male NPT connections on both ends (MNPT x MNPT) at 1\/4 inch pipe size, a stainless steel spring, and a stainless steel seal. The valve has a crack pressure of 3.00 psi, a maximum operating temperature of 250 degrees F, and a minimum operating temperature of 33 degrees F. Licensed plumbers, HVAC technicians, and mechanical contractors install this type of valve in water, air, and refrigerant-adjacent piping applications where reverse flow protection is required.\u003c\/p\u003e\u003cp\u003eThis check valve is suited for use in residential and light commercial plumbing, HVAC, and fluid-handling systems where a compact, threaded inline check valve is needed. Its 1\/4 inch MNPT x MNPT configuration makes it a practical choice for small-diameter pipe runs in supply, control, or instrument lines. The brass body construction offers durability in typical water and air service environments within its rated temperature range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBrass body construction for corrosion resistance in water and air service\u003c\/li\u003e\n\u003cli\u003eStainless steel spring and seal for reliable seating and long service life\u003c\/li\u003e\n\u003cli\u003eMNPT x MNPT end connections for straightforward threaded installation\u003c\/li\u003e\n\u003cli\u003eCrack pressure of 3.00 psi for low-pressure activation\u003c\/li\u003e\n\u003cli\u003eRated for operating temperatures from 33 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.0625 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement check valve for 1\/4 inch NPT threaded piping systems in residential and commercial plumbing and HVAC applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified mechanical technician in accordance with applicable local plumbing codes and IAPMO or IPC guidelines. Shut off and depressurize the supply line completely before removing the existing valve or fitting the new one. Apply thread sealant or PTFE tape to the male threads and hand-tighten before using a wrench to achieve a leak-free joint. Do not exceed the rated maximum temperature of 250 degrees F in service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Check\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: MNPT x MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/4 x 1\/4 inches\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: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrack Pressure\u003c\/strong\u003e: 3.00 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: 33 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141622\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Control Devices\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: M2525-1WA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CONTROL DEVICES","offers":[{"title":"Default Title","offer_id":51541279834418,"sku":"M2525-1WA","price":18.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78eb47d9400dfd4a3c0493197e8def84.jpg?v=1785871311","url":"https:\/\/voomisupply.com\/products\/control-devices-m2525-1wa-brass-check-valve-1-4-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
