Constructed from Grade 316 stainless steel, it delivers strong corrosion resistance in demanding environments including chemical processing, marine applications, and food-service plumbing. The flange has a 7 inch outside diameter and is rated at 150 psi working pressure. Four bolt holes are positioned on 5-1\/2 inch bolt hole centers, with each hole measuring 3\/4 inch. Licensed plumbers and pipefitters install this flange as part of bolted flange connections where threaded end entry is specified.\u003c\/p\u003e\n\u003cp\u003eThis threaded flange is suited for residential and commercial piping installations where stainless steel is required to resist corrosion from water, mild chemicals, or sanitary service media. The threaded connection allows direct engagement onto male-threaded pipe ends without welding, making it practical for retrofit work and field installations where open flame or hot work permits are restricted. It is commonly specified in process piping, water treatment, and industrial plumbing systems operating at 150 psi or below.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for superior corrosion resistance in wet and chemical service environments\u003c\/li\u003e\n  \u003cli\u003eThreaded connection type eliminates the need for welding during installation\u003c\/li\u003e\n  \u003cli\u003e150 psi pressure rating suitable for standard low-pressure piping service\u003c\/li\u003e\n  \u003cli\u003e7 inch outside diameter with 4 bolt holes on 5-1\/2 inch bolt hole centers\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch bolt hole diameter for standard flange hardware\u003c\/li\u003e\n  \u003cli\u003eCircular shape with uniform bolt hole pattern for consistent sealing and alignment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation threaded pipe flange for 2-1\/2 inch pipe systems rated at 150 psi class service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or ASME B31 piping code requirements. Isolate and depressurize the piping system completely before installing or removing any flange. Apply an appropriate thread sealant or PTFE tape to the male pipe threads before threading the flange into position. Torque flange bolts evenly in a cross pattern using a calibrated torque wrench to achieve a proper gasket seal without distortion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Hole Centers\u003c\/strong\u003e: 5-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Hole Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Bolt Holes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Circle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175300\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: MERIT BRASS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 635-40\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51541204992306,"sku":"635-40","price":372.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c69dcd148b8c65ccffc6b549259af1c8_f8a7dc88-6a63-4d9c-9835-b648a980acb6.jpg?v=1785870104","url":"https:\/\/voomisupply.com\/products\/merit-brass-635-40-threaded-pipe-flange-2-1-2-in-ss316","provider":"Voomi Supply","version":"1.0","type":"link"}
