It measures 2.125 inches inside diameter, 2.313 inches outside diameter, and 0.094 inches thick, with a round cross-section profile. The fluoroelastomer compound delivers a 75 Shore A hardness rating, wide chemical compatibility, and a working temperature range of -15 degrees F to 400 degrees F. These characteristics make it well suited for high-temperature service, vacuum service, and environments where low gas permeability is critical.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is used in residential and commercial applications wherever a Dash 138 standard-size seal is specified. Common install scenarios include refrigeration service valves, hydraulic fittings, pump housings, and plumbing unions that contact petroleum-based fluids, oils, or fuels. The brown fluoroelastomer compound is compatible with petroleum products and offers low compression set, meaning it holds its seal shape under sustained clamping load. Technicians working on fuel systems, chemical lines, or high-temperature HVAC components regularly specify this size and material combination.

Always depressurize and lock out the system before replacing any seal. Inspect the groove and mating surfaces for nicks or corrosion that could prevent proper seating. Apply a thin film of compatible lubricant to the O-ring during installation to reduce the risk of twisting or tearing; do not use lubricants that are incompatible with fluoroelastomer compounds.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer (Viton-type)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 138\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.125 inches (53.64 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.313 inches (58.88 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: 75 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: -15 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 400 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Material\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Brown\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: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: ZMSCVB75138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707086537010,"sku":"ZMSCVB75138","price":15.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f0e36f9f99629f739efd82c3e8c67be_dd7895cb-d2ef-47d3-b7eb-edfa82bdbbb8.jpg?v=1788438287","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscvb75138-viton-o-ring-dash-138","provider":"Voomi Supply","version":"1.0","type":"link"}
