It measures 3.875 inches inner diameter by 4.125 inches outer diameter with a 0.125-inch cross-section thickness. Rated at 90 durometer (extra hard), this O-ring delivers excellent compression set resistance along with strong tear and abrasion resistance. Its operating temperature range spans -40 to 250 degrees F, making it suitable for a broad range of service environments. Licensed plumbers, hydraulic technicians, and industrial maintenance professionals specify this compound for petroleum-based fluid systems.\u003c\/p\u003e\n\u003cp\u003eBuna-N O-rings in the Dash 241 size are commonly used in hydraulic fittings, pneumatic assemblies, pump housings, valve stems, and pipe flange seals where petroleum-based fluids or oils are present. This size is a standard fit in many industrial and trade applications including HVAC refrigerant-adjacent fittings, plumbing equipment, and fluid power components. Each package contains 25 O-rings. Note: Buna-N should not be stored in direct sunlight or near motors and other electrical equipment that may generate ozone, as ozone exposure degrades this elastomer over time.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) compound offers excellent resistance to petroleum products and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003e90 durometer extra-hard rating provides strong compression set and dimensional stability under pressure\u003c\/li\u003e\n  \u003cli\u003eWide temperature range of -40 to 250 degrees F suits diverse industrial and trade service conditions\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile meets SAE and MIL-Spec standards for dimensional consistency\u003c\/li\u003e\n  \u003cli\u003eSold in a 25-piece package quantity for bench stock and service kits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with petroleum-based products and hydraulic fluids.

Lightly lubricate the O-ring with a compatible fluid before seating to prevent pinching or rolling during assembly. Avoid using sharp tools that may nick the sealing surface of the O-ring or the gland. Consult applicable system service documentation to verify gland dimensions and compression ratio before installation.\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\u003eDash Number\u003c\/strong\u003e: 241\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.875 inches (98.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.125 inches (104.77 mm)\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: 90 Durometer (Extra 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\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\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: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.02 pounds\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: ZMSCH90241\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693899612466,"sku":"ZMSCH90241","price":16.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e63e5be40384736fb1f090e4d0cdd585_e4349eaf-5f1a-4b69-b750-435ad56bdde5.jpg?v=1788318774","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90241-o-ring-dash-241-nbr-90-duro","provider":"Voomi Supply","version":"1.0","type":"link"}
