Rated at 70 Shore A hardness, this O-ring carries FDA approval and meets SAE and MIL-Spec standards. It is sold in a package of 25 and is used across plumbing, HVAC, and hydraulic fluid system applications wherever a small-diameter, petroleum-resistant seal is needed. Licensed plumbers, HVAC technicians, and fluid system mechanics routinely stock this size for routine maintenance and repair work.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in residential and light commercial systems where sealing against petroleum-based fluids, oils, and fuels is required. The Buna-N compound performs across a wide service temperature range of -40 degrees F to 250 degrees F, making it appropriate for both refrigeration-adjacent and high-temperature fluid applications. The FDA-approved white compound also makes it acceptable for use in food-grade or potable-water-adjacent equipment where compliance is a requirement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFDA-approved Buna-N (NBR) compound suitable for food-grade and potable-water-adjacent applications\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards for broad application acceptance\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating provides excellent compression set and tear resistance\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eExcellent resistance to petroleum products, oils, and fuels\u003c\/li\u003e\n  \u003cli\u003eRound cross section, Dash 007 sizing — a widely stocked standard trade size\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 25 to support service inventory and batch repairs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum-based fluids and products per manufacturer specification. Designed as a standard Dash 007 replacement O-ring for use in plumbing valves, HVAC service ports, hydraulic fittings, and fluid handling components requiring an NBR seal. Not recommended for use with ozone, direct sunlight exposure, or near motors and electrical equipment that may generate ozone.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber, HVAC technician, or qualified fluid system mechanic. Always depressurize and isolate the system before removing or replacing O-rings, and verify that residual fluid has been cleared from the line. Lubricate the O-ring with a compatible lubricant before seating to reduce the risk of tearing during assembly. Do not store unused O-rings in direct sunlight or near motors and other electrical equipment that may generate ozone, as this will degrade the NBR compound over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber, NBR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 007\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.281 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\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 Fluids\u003c\/strong\u003e: Petroleum products\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: Yes\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: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0497 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: ZMSCH70FDA007\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709207675186,"sku":"ZMSCH70FDA007","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_96d95eee-eade-4be2-afbe-891069c6c113.jpg?v=1788452858","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70fda007-o-ring-dash-007-buna-n-fda-25pk","provider":"Voomi Supply","version":"1.0","type":"link"}
