Rated at Shore 70 hardness, this white FDA-approved O-ring is sold in a package of 10. It is designed for static and dynamic sealing applications where contact with petroleum-based fluids is expected. Buna-N is the most widely used O-ring elastomer in trade service, offering excellent compression set resistance along with strong tear and abrasion resistance. Licensed plumbers, HVAC technicians, and maintenance mechanics install this part as a sealing component in pumps, valves, fittings, and fluid-handling assemblies.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in residential and commercial plumbing, HVAC refrigeration lines, hydraulic systems, and industrial fluid-handling equipment where petroleum product compatibility is required. The FDA-approved white Buna-N compound makes it appropriate for applications subject to food-contact regulations or sanitary standards. It meets SAE and MIL-Spec standards, supporting use across both commercial trade and light industrial environments. The Dash 234 designation is a standard AS568 sizing reference used across a wide range of OEM and aftermarket seal applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFDA-approved white Buna-N compound suitable for food-contact and sanitary applications\u003c\/li\u003e\n  \u003cli\u003eShore 70 hardness rating provides firm, reliable sealing under compression\u003c\/li\u003e\n  \u003cli\u003eExcellent resistance to petroleum products, oils, and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eRound cross section conforms to standard O-ring groove dimensions for Dash 234\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards; UNSPSC Code 31401503\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 234 replacement O-ring compatible with petroleum products and systems where Buna-N elastomer is specified. Compatible material includes petroleum-based fluids. Should not be used in applications exposed to direct sunlight, ozone sources, or electrical equipment that generates ozone.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or qualified mechanics during valve, pump, or fitting service. Always depressurize and isolate the system before removing the old O-ring. Lubricate the O-ring lightly with a compatible fluid or O-ring lubricant before seating to prevent damage during assembly. Do not store O-rings in direct sunlight or near motors and other equipment that may generate ozone, as this can degrade the elastomer 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)\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: 234\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.984 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.25 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: Shore 70 (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: 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: 2.79 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8 inches L x 6 inches W x 1 inch H\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: ZMSCH70FDA234\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717467930930,"sku":"ZMSCH70FDA234","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ebb6027b447e35e3946e796977c9a54.jpg?v=1788540970","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70fda234-o-ring-dash-234-buna-n-fda","provider":"Voomi Supply","version":"1.0","type":"link"}
