It features a 3.5-inch outside diameter, a 150 psi pressure rating, and a four-bolt-hole pattern on a 2.375-inch bolt circle. The threaded end accepts standard NPT pipe, making field assembly straightforward without welding. Plumbers, pipefitters, and industrial maintenance technicians install this type of flange in corrosive-fluid and high-moisture environments where Grade 316 stainless provides superior resistance to chlorides and chemical exposure.\u003c\/p\u003e\n\u003cp\u003eThis flange is suited for use in residential and commercial plumbing, marine piping, food-service lines, and chemical-handling systems where stainless construction and threaded connections are required. The 150-class pressure rating aligns with standard low-pressure service applications. Each bolt hole measures 0.625 inches in diameter, accommodating standard flange fastener hardware. It is sold as a single unit and is a practical choice for maintenance, repair, and new installation work on 0.5-inch nominal pipe runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for corrosion resistance in chloride and chemical environments\u003c\/li\u003e\n  \u003cli\u003eThreaded connection type accepts standard NPT pipe — no welding required for assembly\u003c\/li\u003e\n  \u003cli\u003e150 psi pressure rating suitable for standard low-pressure piping service\u003c\/li\u003e\n  \u003cli\u003eFour-bolt-hole pattern on a 2.375-inch bolt circle for secure flanged joint assembly\u003c\/li\u003e\n  \u003cli\u003e3.5-inch outside diameter with 0.625-inch bolt holes sized for standard flange hardware\u003c\/li\u003e\n  \u003cli\u003eCircular shape with uniform bolt hole spacing for proper load distribution at the joint\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation threaded pipe flange for 0.5-inch nominal pipe systems operating at 150-class pressure ratings.\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 and ASME B16.5 or B16.15 standards. Shut off and depressurize the pipe system completely before removing or installing any flange. Apply appropriate thread sealant or PTFE tape to the NPT threads before making up the threaded connection. Torque flange bolts evenly in a cross pattern to ensure uniform gasket compression and a leak-free joint.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 0.5 inches nominal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Circle Diameter\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Hole Diameter\u003c\/strong\u003e: 0.625 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\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\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Circular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 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: 635-08\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51543107961138,"sku":"635-08","price":116.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c69dcd148b8c65ccffc6b549259af1c8_4ed3d724-8059-44c7-80e3-00b996526095.jpg?v=1785915657","url":"https:\/\/voomisupply.com\/products\/merit-brass-635-08-threaded-pipe-flange-316-ss-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
