The ring measures 2.725 inches inside diameter, 3.125 inches outside diameter, and 0.1875 inches thick with a round cross section. Hardness is rated at 70 Shore A, classified as hard. The NBR compound delivers excellent resistance to petroleum products along with strong compression set, tear resistance, and abrasion resistance. Sold in a package of 10 rings. This O-ring is installed by plumbers, pipefitters, HVAC technicians, and maintenance mechanics working on fluid-handling and sealing applications.\u003c\/p\u003e\n\u003cp\u003eThe ZMSCH70FDA335 is designed for use in systems that handle petroleum-based fluids, hydraulic media, water, and compatible process fluids. Its FDA-approved white NBR compound makes it appropriate for equipment where incidental food contact compliance is required, such as food processing or beverage handling machinery. The operating temperature range spans -40 degrees F to 250 degrees F, supporting both refrigeration-adjacent and moderate-heat service environments. The Dash 335 designation conforms to standard AS568 sizing used across industrial, HVAC, plumbing, and OEM equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFDA-approved white NBR (BUNA-N) compound suitable for food-contact-compliant sealing\u003c\/li\u003e\n  \u003cli\u003eDash 335 standard sizing: 2.725 inches ID, 3.125 inches OD, 0.1875 inches thick\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness provides firm sealing under mechanical compression\u003c\/li\u003e\n  \u003cli\u003eOperating range from -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eExcellent resistance to petroleum products, hydraulic fluids, and similar media\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\u003eCompatible with petroleum products and petroleum-based fluids per manufacturer specifications.

Inspect the groove and mating surfaces for burrs or damage before seating the ring to prevent premature failure. Lubricate the O-ring with a compatible fluid or grease prior to installation to avoid tearing during assembly. Follow applicable codes such as IPC or IFGC for plumbing and gas-line service where O-ring seals are used in fittings or valves.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.725 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 335\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (NBR\/BUNA-N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\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: 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\u003ePackage Weight\u003c\/strong\u003e: 5.77 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6 inches L x 4 inches W x 1 inch H\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: ZMSCH70FDA335\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51713756201266,"sku":"ZMSCH70FDA335","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_16493741-7718-4103-aeb7-7c1f60d16638.jpg?v=1788495064","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70fda335-o-ring-dash-335-nbr-fda","provider":"Voomi Supply","version":"1.0","type":"link"}
