It measures 10 inches inside diameter, 10.25 inches outside diameter, and 0.125 inches thick, with a round cross section and a Shore hardness rating of 70. Buna-N is the most widely used O-ring elastomer in trade applications, valued for its excellent resistance to petroleum-based fluids, strong compression set retention, and resistance to tearing and abrasion. Licensed plumbers, pipefitters, and mechanical contractors install this size in large-bore assemblies.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for residential and commercial plumbing, HVAC, pool equipment, and general industrial applications where sealing against petroleum-based fluids or hydraulic media is required. The Dash 274 designation identifies the standard AS568 sizing, making it straightforward to cross-reference against existing seal specifications on the job. It is appropriate for static and low-dynamic sealing applications within its rated temperature range. Sold in a package quantity of 5, it covers multiple service calls or replacement needs from a single order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (nitrile butadiene rubber) construction with excellent resistance to petroleum products and hydraulic fluids\u003c\/li\u003e\n\u003cli\u003eDash 274 AS568 standard sizing for straightforward cross-referencing\u003c\/li\u003e\n\u003cli\u003eShore hardness of 70 for firm compression set and reliable sealing under pressure\u003c\/li\u003e\n\u003cli\u003eRated from -40 degrees F to 250 degrees F for broad service temperature coverage\u003c\/li\u003e\n\u003cli\u003eRound cross section for consistent groove fit and even sealing contact\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products and petroleum-based hydraulic fluids.

Depressurize and shut off fluid supply to the system before removing the existing seal. Inspect the O-ring groove for nicks, corrosion, or debris before seating the new ring. Avoid rolling or twisting the O-ring during installation to prevent cross-section distortion that can lead to seal failure. Do not store unused O-rings near motors, electrical equipment, or in direct sunlight, as ozone exposure degrades nitrile rubber.\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\u003eDash Number\u003c\/strong\u003e: 274\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 10.25 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\u003eShore Hardness\u003c\/strong\u003e: 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\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Media\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: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: ZMSCH70274\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717660049714,"sku":"ZMSCH70274","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9ea7b2e51af3bfe5f52ab4afb07b7fc4.jpg?v=1788544015","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70274-o-ring-nitrile-dash-274","provider":"Voomi Supply","version":"1.0","type":"link"}
