With an inside diameter of 4 mm, an outside diameter of 6 mm, and a thickness of 1 mm, this round cross-section ring carries a Shore 70A hardness rating. The silicone compound supports a working temperature range of -80 degrees F to 450 degrees F, making it suitable for systems that must perform reliably under extreme heat or cold. Each package contains 25 pieces. Licensed HVAC technicians, plumbers, and industrial maintenance professionals regularly install O-rings of this type during equipment overhauls, valve rebuilds, and pump service work.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is used across residential and commercial applications wherever a small-diameter silicone seal is required. Silicone compound is well suited for environments with exposure to dry heat, outdoor weathering, and ozone. The material provides limited oil resistance and handles many common chemicals and solvents. Typical install scenarios include sensor fittings, solenoid valve bodies, low-pressure fluid connections, and HVAC component housings where thermal cycling is a primary concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicone compound rated for -80 degrees F to 450 degrees F continuous service\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile, 1 mm thick, for consistent groove seating\u003c\/li\u003e\n  \u003cli\u003eShore 70A hardness provides firm compression with reliable sealing force\u003c\/li\u003e\n  \u003cli\u003eGood weather and ozone resistance for outdoor or exposed installations\u003c\/li\u003e\n  \u003cli\u003eCompatible with oils, chemicals, and solvents in appropriate concentrations\u003c\/li\u003e\n  \u003cli\u003eSold in a 25-piece package to support service inventory or single-job needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement silicone O-ring for equipment requiring a 4 mm ID by 6 mm OD by 1 mm thick round cross-section seal in silicone compound.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or industrial mechanics as part of valve, pump, or fitting service. De-energize electrical systems and shut off fluid supply lines before disassembling any sealed component. Inspect the mating groove for nicks, corrosion, or debris before seating the O-ring, and avoid twisting the ring during installation. Follow applicable codes such as IPC or IFGC for plumbing and gas piping applications where O-ring seals are used at fittings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Silicone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1 mm\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: Shore 70A (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\u003ePackage Quantity\u003c\/strong\u003e: 25 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: USA INDUSTRIALS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZUSAS1x4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"USA INDUSTRIALS","offers":[{"title":"Default Title","offer_id":52057100615986,"sku":"ZUSAS1x4","price":30.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4057a4fa90d46cc4833223ab26f5850d_e17f4ca9-edca-4d1a-9edb-c0e29c23f734.jpg?v=1790038661","url":"https:\/\/voomisupply.com\/products\/usa-industrials-zusas1x4-silicone-o-ring-4mm-id-6mm-od","provider":"Voomi Supply","version":"1.0","type":"link"}
