It connects threaded pipe ends to mating flanges in pressure piping systems, providing a removable, leak-resistant joint. The 316 stainless construction offers strong resistance to corrosion and oxidation, making it a reliable choice in wet, chemical-exposure, or marine-adjacent environments. Rated at 150 psi, this flange suits standard low-pressure piping service. Plumbers and pipefitters install it on commercial and industrial systems where threaded connections and corrosion resistance are both required.\u003c\/p\u003e\n\u003cp\u003eThis flange is suited for use in plumbing, process piping, and light industrial systems operating at up to 150 psi. The four-bolt-hole pattern on a 3.125-inch bolt hole center circle is a standard layout for 1-inch Class 150 flanged connections. It is commonly installed in water supply lines, chemical handling systems, and marine or coastal mechanical systems where Grade 316 stainless is specified for its elevated chloride resistance compared to 304-series alloys.\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 harsh or wet environments\u003c\/li\u003e\n  \u003cli\u003eThreaded connection type for straightforward installation on standard threaded pipe ends\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 centered at 3.125 inches across bolt hole centers\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch bolt holes sized to accept standard Class 150 flange hardware\u003c\/li\u003e\n  \u003cli\u003eCircular flange shape with 4.25-inch outside diameter for 1-inch pipe sizing\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 1-inch pipe in Class 150 threaded flange applications.\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 plumbing codes such as the IPC. Shut off and depressurize the piping system completely before removing or installing any flange. Thread the flange fully onto the pipe end using appropriate thread sealant or PTFE tape rated for the service fluid. Torque flange bolts evenly in a cross pattern to achieve uniform gasket compression, referencing the applicable flange standard for bolt load guidance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Hole Centers\u003c\/strong\u003e: 3.125 inches across\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Hole Size\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: Circle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.45 pounds\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: 635-16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51538988532018,"sku":"635-16","price":161.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe6014db7e340d4ccf3c6266d83f057a.jpg?v=1785831939","url":"https:\/\/voomisupply.com\/products\/merit-brass-635-16-threaded-pipe-flange-1-in-316-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
