It measures 3.75 inches inside diameter, 4 inches outside diameter, and 0.125 inches thick with a round cross-section. The compound carries a Shore A hardness of 75, placing it in the hard durometer range. Viton fluoroelastomer provides strong resistance to petroleum-based fluids, high temperatures up to 400 degrees F, and a wide range of chemicals. Low compression set and low gas permeability make this O-ring a reliable choice in static and dynamic sealing applications where hydrocarbon exposure or elevated temperatures are a concern.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for use in HVAC refrigerant systems, hydraulic assemblies, fuel handling equipment, compressor fittings, and industrial process lines where petroleum products, oils, or high-temperature gases are present. Plumbers, HVAC technicians, and industrial maintenance professionals commonly use Dash 240 O-rings as face-seal or port-seal replacements in standard AN and SAE port configurations. The -15 to 400 degrees F operating range covers most residential and light commercial mechanical system environments as well as many demanding industrial service conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton) material provides broad chemical compatibility and high-temperature performance\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -15 degrees F to 400 degrees F\u003c\/li\u003e\n\u003cli\u003eShore A hardness of 75 for reliable sealing under compression\u003c\/li\u003e\n\u003cli\u003eLow compression set helps maintain a consistent seal over extended service cycles\u003c\/li\u003e\n\u003cli\u003eLow gas permeability makes this O-ring suitable for vacuum and gas-containment service\u003c\/li\u003e\n\u003cli\u003eSold in a pack of 5 to support multiple repairs or installations from a single order\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products, oils, and a wide spectrum of chemical media.

Always depressurize and isolate the system before removing the old O-ring, and clean the mating groove thoroughly to remove debris or residual sealant. Avoid rolling or twisting the O-ring during installation, and apply a compatible lubricant to reduce the risk of nicking the material. Follow applicable system-specific codes and manufacturer service procedures when returning the assembly to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer (Viton)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 240\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.75 inches (94.84 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4 inches (101.90 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches (3.53 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 (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\u003eCompatible Media\u003c\/strong\u003e: Petroleum products, oils, broad chemical spectrum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Brown\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: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\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: ZMSCVB75240\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723819254066,"sku":"ZMSCVB75240","price":18.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f0e36f9f99629f739efd82c3e8c67be_54f517d9-0403-4726-9e2c-e4da13190b35.jpg?v=1788608384","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscvb75240-viton-o-ring-dash-240-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
