It measures 2.484 inches inside diameter, 2.75 inches outside diameter, and 0.125 inches thick with a round cross section. Hardness is rated at 70 Shore A, placing it in the hard category. This O-ring is suited for static and dynamic sealing in fluid systems across plumbing, HVAC, hydraulic, and industrial maintenance applications. Licensed plumbers, pipefitters, and maintenance technicians are the primary installers. Sold in packs of 10.\u003c\/p\u003e\u003cp\u003eBuna-N is the most widely used O-ring elastomer in trade applications. This part is a direct fit for sealing applications involving petroleum-based fluids, water, and mild chemicals. It performs across a temperature range of -40 degrees F to 250 degrees F, making it appropriate for both chilled-water and hot-water piping systems, pump housings, valve bonnets, and compressor fittings. The FDA-approved white compound also makes it suitable for potable water and food-processing equipment where material compliance is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFDA-approved Buna-N compound rated for food-contact and potable water applications\u003c\/li\u003e\n\u003cli\u003eRated from -40 degrees F to 250 degrees F operating temperature range\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness for reliable compression set performance in high-cycle applications\u003c\/li\u003e\n\u003cli\u003eExcellent resistance to petroleum products, hydraulic fluids, and mineral oils\u003c\/li\u003e\n\u003cli\u003eRound cross section for consistent sealing across standard O-ring grooves\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards for dimensional and material compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products and systems requiring Buna-N elastomer seals.

Always depressurize the system and shut off all fluid supply before removing the existing seal. Inspect the mating groove for surface damage or debris before seating the new O-ring. Do not store unused O-rings in direct sunlight or near motors and electrical equipment that may generate ozone, as this degrades the elastomer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 230\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.484 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 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: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.31 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: ZMSCH70FDA230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694606385458,"sku":"ZMSCH70FDA230","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/677e497d29bf51979a9a285f4ea409b4.jpg?v=1788326170","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70fda230-o-ring-dash-230-buna-n-fda","provider":"Voomi Supply","version":"1.0","type":"link"}
