It measures 0.25 inches inside diameter, 0.438 inches outside diameter, and 0.094 inches thick with a round cross section. Rated at 90 durometer (extra hard), this O-ring provides excellent compression set resistance along with strong tear and abrasion resistance. The temperature range spans -40 to 250 degrees F, making it suitable for a broad range of service conditions. Licensed trades and maintenance technicians working with hydraulic, pneumatic, and fluid systems rely on this standard AS568 dash size for reliable sealing performance.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is used across residential and commercial HVAC, plumbing, refrigeration, and general mechanical applications wherever a Dash 108 sealing element is required. It is particularly well suited for use with petroleum-based fluids and oils, making it a common choice in compressor service, pump assemblies, valve bodies, and hydraulic fittings. The Buna-N formulation offers excellent resistance to petroleum products, fuels, and lubricating oils. Sold in a package quantity of 100, this item is well suited for shop stock or field service kits where multiple O-rings of this size are consumed regularly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction with excellent resistance to petroleum products\u003c\/li\u003e\n  \u003cli\u003e90 durometer extra hard rating for strong compression set and sealing performance\u003c\/li\u003e\n  \u003cli\u003eDash 108 standard sizing: 0.25 inches ID, 0.438 inches OD, 0.094 inches thick\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 100 units for shop stock or service kit replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products, lubricating oils, fuels, and hydraulic fluids. Designed as an OEM-style replacement Dash 108 O-ring for use in HVAC, plumbing, hydraulic, and general mechanical sealing applications where Buna-N elastomer material is specified. Note: Buna-N is not recommended for use with ozone-generating environments, direct sunlight exposure, or systems using incompatible solvents or glycol-based fluids.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eO-ring installation is performed by licensed HVAC technicians, plumbers, and maintenance mechanics depending on the application. Always depressurize and de-energize the system before replacing O-rings, and relieve any residual fluid pressure before disassembly. Inspect the seating groove for damage or debris before installing the new O-ring, and apply a compatible lubricant to ease installation and prevent pinching or rolling. Do not store unused Buna-N O-rings in direct sunlight or near motors and electrical equipment that may generate ozone, as this degrades the elastomer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 108\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.25 inches (6.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.438 inches (11.12 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.094 inches (2.62 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: 90 Durometer (Extra Hard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 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 Fluids\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\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\u003eWeight\u003c\/strong\u003e: 0.17 pounds\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: ZMSCH90108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721647718706,"sku":"ZMSCH90108","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14fd8ed23175006e4397cdd9da1af04f.jpg?v=1788579159","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90108-o-ring-dash-108-nbr-pack-100","provider":"Voomi Supply","version":"1.0","type":"link"}
