It measures 5 inches inner diameter, 5.25 inches outer diameter, and 0.125 inches thick. With a 70 Shore A hardness rating, this O-ring is formulated for demanding fluid-sealing applications where resistance to heat, steam, and aggressive hydraulic fluids is required. It is used by plumbers, mechanical contractors, and maintenance technicians in systems carrying hot water, steam, and phosphate ester hydraulic fluids. Each package contains 10 O-rings.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial plumbing, industrial fluid systems, and hydraulic applications requiring reliable sealing across a wide temperature range. It is especially well-suited for use with Skydrol-type phosphate ester hydraulic fluids common in commercial aircraft ground-support and hydraulic maintenance applications. It also performs in hot water and steam service, and shows resistance to select acids, alkalies, and ozone exposure. NSF 61 certification makes it appropriate for potable water system components where that listing is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEthylene Propylene Rubber construction provides excellent resistance to hot water, steam, and phosphate ester hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eRated for temperatures from -65 degrees F to 300 degrees F\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness — rated Hard — for firm, reliable compression sealing\u003c\/li\u003e\n  \u003cli\u003eRound cross section, Dash 250 sizing for standardized fitment\u003c\/li\u003e\n  \u003cli\u003eNSF 61 listed for potable water system compatibility\u003c\/li\u003e\n  \u003cli\u003eResistant to select acids, alkalies, and ozone\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in systems handling hot water, steam, and phosphate ester type hydraulic fluids including Skydrol-type fluids used in commercial aircraft hydraulic systems.

Always depressurize and drain the system before removing or replacing seals. Inspect the seating groove for damage, corrosion, or contamination before installing the new O-ring. Avoid twisting the O-ring during installation; use a compatible lubricant approved for EPR compounds and the fluid being sealed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Ethylene Propylene Rubber (EPR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches (3.53 mm)\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: -65 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 300 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Fluids\u003c\/strong\u003e: Hot water, steam, phosphate ester hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: NSF 61\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: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.34 pounds (package)\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: ZMSCE70NSF250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697700634930,"sku":"ZMSCE70NSF250","price":41.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bedbb31a52481aa0d89659b36d335e1c.jpg?v=1788354180","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsce70nsf250-o-ring-dash-250-epr-10-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
