It measures 1.875 inches inside diameter, 2.25 inches outside diameter, and 0.1875 inches thick. Rated at 70 Shore A hardness, this O-ring is formulated from ethylene propylene diene monomer (EPDM) rubber, which provides strong resistance to hot water, steam, and phosphate ester hydraulic fluids. It operates across a wide temperature range, from -65 degrees F to 300 degrees F, making it suitable for demanding thermal environments. Licensed plumbers, HVAC technicians, and hydraulic system technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is commonly used in plumbing, HVAC, and hydraulic sealing applications where exposure to hot water or steam is expected. It is also rated for use with phosphate ester type hydraulic fluids, including Skydrol fluids used in commercial aircraft hydraulic systems. Typical install scenarios include sealing joints in water heating systems, steam distribution lines, and industrial hydraulic circuits. Each purchase includes 25 O-rings packaged together.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEPDM material provides excellent resistance to hot water, steam, and phosphate ester hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eRated for Skydrol fluids used in commercial aircraft hydraulic systems\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating for firm, reliable sealing under pressure\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range: -65 degrees F to 300 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross section for consistent contact and uniform compression\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 25 for shop stocking and service vehicle inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with hot water, steam, and phosphate ester hydraulic fluid systems.

Always depressurize and drain the system, or relieve hydraulic pressure fully, before removing the old O-ring or installing the replacement. Inspect the groove and mating surfaces for wear or damage prior to seating the new O-ring. Do not use petroleum-based lubricants with EPDM O-rings, as they can cause swelling and seal failure.\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: 328\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 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\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\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: ZMSCE70328\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721250930994,"sku":"ZMSCE70328","price":22.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2225f36e795e8063a256174e7545fc3.jpg?v=1788575362","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsce70328-epdm-o-ring-dash-328-pack-25","provider":"Voomi Supply","version":"1.0","type":"link"}
