It features an outside diameter of 4-5\/8 inches and is constructed from Grade 316 and 316L stainless steel, providing strong corrosion resistance in demanding environments. Rated at 150 psi, this flange is built for Class 150 piping systems where a secure, leak-tight termination is required. Plumbers, pipefitters, and mechanical contractors install this fitting in commercial and industrial plumbing, process piping, and fluid handling systems.\u003c\/p\u003e\n\u003cp\u003eThis blind flange is suited for use in residential and commercial piping systems where stainless steel is specified for corrosion resistance, sanitary requirements, or chemical compatibility. It fits 1-1\/4 inch pipe schedules consistent with Class 150 ANSI flange standards. The 4-bolt hole pattern with 5\/8 inch bolt holes on 3-1\/2 inch bolt hole centers makes it straightforward to mate with matching Class 150 flanges. Typical applications include water, steam, and process fluid systems where a capped termination point is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 and 316L stainless steel construction for corrosion and chemical resistance\u003c\/li\u003e\n  \u003cli\u003eBlind connection type seals pipe ends in Class 150 flanged systems\u003c\/li\u003e\n  \u003cli\u003e4-5\/8 inch outside diameter with 4-bolt hole pattern\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch bolt holes on 3-1\/2 inch bolt hole centers\u003c\/li\u003e\n  \u003cli\u003e150 psi pressure rating\u003c\/li\u003e\n  \u003cli\u003eCircular shape consistent with standard ANSI Class 150 flange geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for 1-1\/4 inch Class 150 flanged piping systems using ANSI-pattern blind flanges.\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 mechanical and plumbing codes. Depressurize and drain the piping system completely before removing or installing any flange. Use appropriate gasket material and fasteners rated for the system pressure and fluid type. Do not overtighten bolts unevenly — follow a cross-pattern sequence to achieve uniform gasket compression.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Blind\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Hole Size\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Hole Centers\u003c\/strong\u003e: 3-1\/2 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\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316 \/ 316L\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: 3 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: A635BL-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51540495434034,"sku":"A635BL-20","price":770.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c7f6daaa81bfc35b992d4b0a135ef4c_f4906993-e04d-4138-8cf5-1e657f020308.jpg?v=1785856541","url":"https:\/\/voomisupply.com\/products\/merit-brass-a635bl-20-blind-pipe-flange-1-1-4-in-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
