It measures 13 mm inside diameter, 18 mm outside diameter, and 2.5 mm thick. The black Buna-N compound delivers excellent resistance to petroleum-based fluids, strong compression set performance, and good tear and abrasion resistance. Rated at Shore 70 hardness, this O-ring operates across a wide temperature range of -40 degrees F to 250 degrees F. Licensed plumbers, HVAC technicians, and industrial maintenance professionals specify Buna-N O-rings for high-contact sealing environments where petroleum fluid exposure is expected.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in hydraulic systems, pneumatic assemblies, plumbing fittings, fuel handling equipment, and general fluid-sealing applications where contact with petroleum products is anticipated. Its compact metric dimensions make it a common choice for both residential and light commercial service work involving valves, pumps, manifolds, and pipe couplings. It is not approved for use with ozone-generating environments or direct sunlight storage, and should be kept away from motors or electrical equipment that may produce ozone during storage. Sold in packages of 100, this SKU is practical for service shops maintaining a working O-ring inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction — excellent resistance to petroleum products, oils, and fuels\u003c\/li\u003e\n  \u003cli\u003eShore 70 hardness rating provides firm compression set and long-term seal integrity\u003c\/li\u003e\n  \u003cli\u003eRated for service from -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross section for reliable seating in standard O-ring grooves\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eSold in a 100-piece package with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products and petroleum-based fluids. Designed for use in standard O-ring groove applications where Buna-N elastomer is specified. Not recommended for use with ozone, strong oxidizing agents, or non-petroleum synthetic fluids where Buna-N is unsuitable.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance professionals. Always depressurize and shut off fluid supply to the system before replacing any O-ring seal. Inspect the groove and mating surfaces for nicks, burrs, or corrosion before seating the new O-ring. Avoid storing Buna-N O-rings in direct sunlight or near motors and other equipment that may generate ozone, as ozone exposure degrades nitrile rubber 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\u003eInside Diameter\u003c\/strong\u003e: 13 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 18 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 2.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\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: 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 Fluids\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\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: ZMSCH2.5X13\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691638423858,"sku":"ZMSCH2.5X13","price":18.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d46f0eeb24d689bfa74d4d004b3dae1.jpg?v=1788287992","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch2-5x13-buna-n-o-ring-13mm-id","provider":"Voomi Supply","version":"1.0","type":"link"}
