Measuring 1.438 inches inside diameter, 1.688 inches outside diameter, and 0.125 inches thick, this round-cross-section ring is molded from Ethylene Propylene Diene Monomer (EPDM) rubber. It carries a hardness rating of 70 Shore A, which falls in the hard range and provides firm, consistent compression. Rated from -65 degrees F to 300 degrees F, it suits hot-water and steam service as well as phosphate ester hydraulic fluid systems.\u003c\/p\u003e\u003cp\u003eThis O-ring is well suited for plumbing, HVAC hydronic systems, and industrial fluid-handling circuits where hot water, steam, or phosphate ester hydraulic fluids are present. It also offers excellent resistance to Skydrol-type fluids used in commercial aircraft hydraulic systems, making it a practical choice for MRO and aerospace maintenance shops. Licensed plumbers, pipefitters, and industrial maintenance technicians commonly specify Dash 221 EPDM rings for valve stems, pump housings, manifold ports, and threaded union seals in these service environments. Sold in a package quantity of 50 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eEPDM material provides broad chemical resistance to hot water, steam, and phosphate ester hydraulic fluids\u003c\/li\u003e\n\u003cli\u003eRated for continuous service from -65 degrees F to 300 degrees F\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness delivers firm, stable sealing compression\u003c\/li\u003e\n\u003cli\u003eRound cross section ensures uniform compression across the sealing groove\u003c\/li\u003e\n\u003cli\u003eDash 221 standard sizing allows straightforward OEM and MRO replacement\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 50 supports stocking and field service kits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with hot water, steam, and phosphate ester type hydraulic fluids; also suitable for Skydrol-fluid service in commercial aircraft hydraulic systems.

Clean the groove and mating surfaces thoroughly and inspect for scoring or corrosion before installing the new O-ring. Lubricate the O-ring with a compatible fluid or grease rated for EPDM to prevent tearing during assembly. Follow applicable plumbing or mechanical codes, including IPC and ASME B31 references, for system pressure testing after reassembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 221\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.438 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.688 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\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\u003ePackage Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: ZMSCE70221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703720804658,"sku":"ZMSCE70221","price":20.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_bbfccdfa-e497-4655-9090-b7381039f511.jpg?v=1788418220","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsce70221-dash-221-epdm-o-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
