With an inside diameter of 0.0781 inches, an outside diameter of 0.2030 inches, and a cross-section thickness of 0.0625 inches, this is a small-profile ring suited for tight-tolerance fittings and compact assemblies. The round cross-section profile provides consistent compression and reliable sealing contact. Hardness is rated at 70 Shore A, placing it in the hard range for firm, stable seating under pressure. Licensed technicians and service pros working on refrigeration circuits or fluid handling systems install these during routine maintenance, component rebuilds, or system commissioning.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is commonly used in refrigeration and HVAC applications where resistance to Freon and similar refrigerants is required. The neoprene compound also performs well in applications involving moderate petroleum product exposure, outdoor environments, and systems subject to ozone degradation. Typical install scenarios include compressor fittings, valve bodies, flare adapters, and small-bore fluid connections. The 100-piece pack quantity supports service shops and technicians who replace O-rings as consumables during system service calls or preventive maintenance routines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNeoprene compound rated for use with Freon and refrigeration fluids\u003c\/li\u003e\n  \u003cli\u003eDash 004 standard sizing with 0.0781 inch ID and 0.2030 inch OD\u003c\/li\u003e\n  \u003cli\u003eRound cross-section for consistent compression and sealing contact\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness for firm, stable seating in tight-tolerance grooves\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -65 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eModerately resistant to petroleum products with good ozone and weather resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in refrigeration and HVAC fluid circuits requiring a Dash 004 neoprene O-ring with a round cross-section; compatible with Freon-based refrigerants as noted in the product specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eO-rings of this size are typically installed by licensed HVAC technicians or refrigeration mechanics during system service, valve replacement, or fitting assembly. Always depressurize and recover refrigerant from the system before replacing O-rings in any refrigerant circuit, in accordance with EPA Section 608 requirements. Inspect the seating groove for burrs or debris before installation to avoid damage to the O-ring sealing surface. Do not over-compress the ring during assembly, as excess deformation will reduce service life and sealing performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Neoprene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 004\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.0781 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 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\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: -65 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 Fluid\u003c\/strong\u003e: Freon\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: 100\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: ZMSCN70004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693312606514,"sku":"ZMSCN70004","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a85a04616a0b8edf3ad2b4aa4905ae64_60371f06-9c8a-4911-9696-c8753e737254.jpg?v=1788310489","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscn70004-neoprene-o-ring-dash-004","provider":"Voomi Supply","version":"1.0","type":"link"}
