With an 8-inch inside diameter, 8.375-inch outside diameter, and a thickness of 0.1875 inches, this is a Dash 369 standard-size seal. The silicone compound carries a hardness rating of 70 Shore A, which is considered hard and provides good dimensional stability under compression. Silicone material is selected specifically when a wide service temperature range is required, spanning from -80 degrees F to 450 degrees F, making it well suited for environments where standard nitrile or EPDM compounds would fail.\u003c\/p\u003e\u003cp\u003eThis O-ring is appropriate for use in HVAC equipment, plumbing assemblies, pump housings, fluid system manifolds, and general mechanical sealing where exposure to heat, ozone, or weather cycling is a factor. The silicone compound offers good dry heat and ozone resistance. It is sold individually and is suitable for one-for-one replacement of any Dash 369 O-ring of equivalent silicone material and hardness. Service technicians working on air handling units, compressor assemblies, or piping flanges will find this size relevant to large-bore sealing faces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 369 standard sizing: 8 inches ID, 8.375 inches OD, 0.1875 inches thick\u003c\/li\u003e\n\u003cli\u003eSilicone compound rated for service temperatures from -80 degrees F to 450 degrees F\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness for firm compression sealing and dimensional stability\u003c\/li\u003e\n\u003cli\u003eRound cross-section profile for reliable groove seating\u003c\/li\u003e\n\u003cli\u003eCompatible with oils, chemicals, and solvents within silicone resistance limits\u003c\/li\u003e\n\u003cli\u003eGood weather and ozone resistance for outdoor or exposed installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 369 silicone O-ring replacement suitable for any application requiring an 8-inch ID round cross-section seal with silicone material compatibility.

Inspect the groove for burrs, scoring, or debris before seating the new ring. Do not stretch the O-ring over sharp edges without a proper installation tool, and avoid twisting the cross-section during placement. Follow applicable system manufacturer torque specifications for any fasteners used to compress the sealing face.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 8.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 369\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Silicone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Hard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -80 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 450 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible With\u003c\/strong\u003e: Oils, Chemicals, Solvents\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\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\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: ZMSCS70369\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51719443415346,"sku":"ZMSCS70369","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/522062ef0f6aef5885c61161d615a2e8.jpg?v=1788559452","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70369-silicone-o-ring-dash-369","provider":"Voomi Supply","version":"1.0","type":"link"}
