It features a round cross section with a 4.5-inch inside diameter, 4.75-inch outside diameter, and a 0.125-inch thickness. Rated at 70 Shore A hardness, this O-ring provides a firm, reliable seal under pressure. EPDM construction delivers excellent resistance to heat and moisture, making it a practical choice for plumbing, HVAC hydronic systems, and industrial fluid lines. Each package contains 10 O-rings.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial applications involving hot water service, steam lines, and phosphate ester type hydraulic fluids such as Skydrol, which is commonly used in commercial aircraft hydraulic systems. It performs across a wide temperature range, from -65 degrees F to 300 degrees F, covering the demands of most hydronic heating, steam distribution, and fluid power installations. Plumbers, HVAC technicians, and industrial maintenance professionals regularly use this profile for pump flanges, valve seats, and pipe couplings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEPDM material with excellent resistance to hot water, steam, and phosphate ester hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eDash 246 standard profile with round cross section for consistent groove fitment\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating for a firm, reliable seal under load\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range: -65 degrees F to 300 degrees F\u003c\/li\u003e\n  \u003cli\u003ePackaged 10 pieces per unit for job-site convenience\u003c\/li\u003e\n  \u003cli\u003eBlack color for easy visual identification in standard O-ring groove sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with systems handling hot water, steam, and phosphate ester type hydraulic fluids.

Shut down and depressurize the system fully before removing the old O-ring or seating the replacement. Inspect the groove for scoring, corrosion, or debris before installing the new O-ring. Do not stretch or twist the O-ring during installation, as deformation can compromise the seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: EPDM (Ethylene Propylene Diene Monomer)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 246\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.75 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\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\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: ZMSCE70246\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722746757426,"sku":"ZMSCE70246","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/256233d1f871ea4134bb8d44e15c5a70.jpg?v=1788595285","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsce70246-epdm-o-ring-dash-246-10-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
