It measures 1.563 inches inside diameter, 1.750 inches outside diameter, and 0.094 inches thick with a round cross section. The fluoroelastomer compound delivers a Shore A hardness of 75, low compression set, and broad chemical compatibility. The temperature range spans -15 degrees F to 400 degrees F, making it suitable for both high-temperature service and moderate cryogenic exposure. Each package contains 25 rings.\u003c\/p\u003e\u003cp\u003eThis O-ring is appropriate for use in petroleum-based fluid systems, hydraulic assemblies, fuel handling equipment, and vacuum service applications. Its low gas permeability and high temperature resistance make it a common choice for refrigerant circuit fittings, fuel line connections, and pump seals in both residential and commercial mechanical systems. Plumbers, HVAC technicians, and industrial maintenance professionals install this O-ring wherever a Dash 129 fluoroelastomer seal is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton-type) material for high resistance to petroleum products and fuels\u003c\/li\u003e\n\u003cli\u003eOperating range of -15 degrees F to 400 degrees F suits high-temperature HVAC and fuel applications\u003c\/li\u003e\n\u003cli\u003eShore A hardness of 75 with low compression set for long-term sealing integrity\u003c\/li\u003e\n\u003cli\u003eLow gas permeability makes it suitable for vacuum service\u003c\/li\u003e\n\u003cli\u003eWide spectrum of chemical compatibility reduces the need for multiple seal types on a job\u003c\/li\u003e\n\u003cli\u003eSold in a pack of 25 to support service inventory and reduce per-unit cost\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 129 O-ring replacement compatible with systems that specify fluoroelastomer seals for use with petroleum products and high-temperature fluids.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician following applicable system codes such as IFGC or IPC where gas or fluid lines are involved. Always depressurize and isolate the system before removing any seals. Inspect the groove and mating surface for scoring or debris before seating the new O-ring. Do not use petroleum-based lubricants unless confirmed compatible with the system fluid; use an appropriate assembly lubricant rated for fluoroelastomer compounds.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer (Viton-type)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 129\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.563 inches (39.34 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.750 inches (44.58 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.094 inches (2.62 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShore A Hardness\u003c\/strong\u003e: 75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Hard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -15 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 400 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Material\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.21 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZMSCVB75129\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693332201778,"sku":"ZMSCVB75129","price":20.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f0e36f9f99629f739efd82c3e8c67be_1a5db8f4-5e8d-4543-bdcc-123c9a513845.jpg?v=1788310778","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscvb75129-viton-o-ring-dash-129-25pk","provider":"Voomi Supply","version":"1.0","type":"link"}
