Constructed from 316 stainless steel; corrosion resistance and mechanical strength are inherent properties, compatible with air, natural gas, non-potable water, and propane within the device's rated operating ranges. This coupling includes a standard nitrile seal to provide a leak-tight seal under defined operating conditions and is suitable for axial movement within piping systems. It meets various standards including ANSI, ASTM 1476, AWWA C227-07, ISO, and NP-15837\/15838, and is certified as low lead compliant for potable water systems.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial: 316 stainless steel with polished finish\u003c\/li\u003e\n\u003cli\u003eNominal pipe size: 3 inches\u003c\/li\u003e\n\u003cli\u003eOverall length: 3 11\/16 inches (3-45\/64 inches)\u003c\/li\u003e\n\u003cli\u003eMaximum operating pressure: 232 psi\u003c\/li\u003e\n\u003cli\u003eTemperature range: -4°F to 180°F\u003c\/li\u003e\n\u003cli\u003eIncludes 2 bolts made of 316 stainless steel with 89mm Hex heads\u003c\/li\u003e\n\u003cli\u003eSeal material: Nitrile, included to provide a leak-tight seal under defined operating conditions\u003c\/li\u003e\n\u003cli\u003eDesigned for use with air, natural gas, non-potable water, and propane within the product's rated pressure and temperature ranges\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv class=\"nbs-spec-wrap\" style=\"overflow-x:auto;-webkit-overflow-scrolling:touch;\"\u003e\u003ctable class=\"nbs-spec-table\" style=\"width:100%;max-width:100%;border-collapse:collapse;font-size:0.95em;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:8px 10px;border:1px solid #d9dee5;background:#f4f6f9;width:38%;\"\u003eBrand\u003c\/th\u003e\n\u003ctd style=\"padding:8px 10px;border:1px solid #d9dee5;\"\u003eStraub\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:8px 10px;border:1px solid #d9dee5;background:#f4f6f9;width:38%;\"\u003eManufacturer Part Number\u003c\/th\u003e\n\u003ctd style=\"padding:8px 10px;border:1px solid #d9dee5;\"\u003eG20651-SI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003c\/div\u003e\n\u003cdiv class=\"nbs-b2b-callout\" style=\"border-left:4px solid #1F3A5F;background:#f4f6f9;padding:12px 16px;margin:18px 0 0;\"\u003e\n\u003cp style=\"margin:0 0 6px;\"\u003e\u003cstrong\u003eOEM Part Verification:\u003c\/strong\u003e Confirm Straub part number G20651-SI against your equipment nameplate or parts list before ordering.
