It measures 9.25 inches inside diameter, 9.625 inches outside diameter, and 0.1875 inches (3\/16 inches) thick with a round cross-section profile. Rated at 70 Shore A hardness, this O-ring delivers reliable compression set resistance along with strong tear and abrasion resistance. It is sold in a package quantity of 5 and is suited for installation by licensed plumbers, HVAC technicians, and mechanical contractors working with fluid or gas sealing systems.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is designed for use in applications where petroleum-based fluids or gases are present, including hydraulic systems, pneumatic systems, fuel handling equipment, and general industrial or HVAC sealing points. Its Buna-N compound performs across a wide temperature range, from -40 degrees F to 250 degrees F, making it appropriate for both outdoor and mechanical room environments. It is not FDA approved and should not be used in food-contact or potable-water applications without confirming material suitability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) compound — excellent resistance to petroleum products, hydraulic fluids, and fuels\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating — hard durometer class for reliable sealing under compression\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile conforms to Dash 374 standard dimensions\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eBlack color; package quantity of 5 per order unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products and petroleum-based hydraulic fluids per supplier specifications. Buna-N O-rings should not be exposed to ozone sources, direct sunlight during storage, or electrical equipment generating ozone, as these conditions degrade the elastomer over time.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eO-ring installation is typically performed by licensed plumbers, HVAC technicians, or mechanical contractors. Before replacing any O-ring, de-energize the system, relieve all pressure, and drain or isolate the fluid circuit. Lubricate the O-ring with a compatible lubricant — use only petroleum-compatible grease with Buna-N — and seat the ring evenly in its groove without twisting or stretching. Do not use tools with sharp edges that could nick or cut the sealing surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 9.25 inches (9-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 9.625 inches (9-5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 374\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A (Hard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Media\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\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\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: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZMSCH70374\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715331260722,"sku":"ZMSCH70374","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_e6e260ce-9da5-4fdb-98ca-b62bcda59566.jpg?v=1788512166","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70374-o-ring-dash-374-nitrile-nbr","provider":"Voomi Supply","version":"1.0","type":"link"}
