It measures 2.125 inches inside diameter, 2.313 inches outside diameter, and 0.0937 inches thick. With a 70-durometer hardness rating, this O-ring delivers a firm, reliable seal under compression. The fluoroelastomer compound provides high temperature resistance up to 400 degrees F and performs down to -15 degrees F, making it well suited for HVAC, plumbing, refrigeration, and industrial service where petroleum-based fluids or elevated temperatures are present. Licensed tradespeople and industrial maintenance technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis O-ring is used wherever a Dash 138 size seal is required in systems handling petroleum products, hydraulic fluids, or high-temperature media. Typical applications include pump housings, valve bodies, compressor fittings, and fluid line connections in both residential and commercial mechanical systems. The low compression set characteristic helps maintain a consistent seal over extended service life, and the low gas permeability makes it appropriate for vacuum service applications as well.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton-type) compound with wide chemical compatibility including petroleum products\u003c\/li\u003e\n\u003cli\u003eRated for service from -15 degrees F to 400 degrees F\u003c\/li\u003e\n\u003cli\u003e70-durometer hardness for firm, stable sealing under load\u003c\/li\u003e\n\u003cli\u003eLow compression set extends service life in static and dynamic sealing applications\u003c\/li\u003e\n\u003cli\u003eLow gas permeability supports vacuum service use\u003c\/li\u003e\n\u003cli\u003eRound cross section for standard O-ring groove fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Dash 138 standard O-ring replacement compatible with systems and components requiring a 2.125-inch ID fluoroelastomer seal, particularly those in contact with petroleum products and high-temperature media.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance mechanics. Shut down and depressurize the system completely before removing the old O-ring or installing the replacement. Lightly lubricate the O-ring with a compatible fluid or grease before seating it in the groove to prevent tearing during assembly. Avoid overstretching the O-ring during installation, as this can reduce sealing performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer (Viton-type)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.313 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 inches (3\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 138\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 durometer (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 Media\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\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: 0.02 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: ZMSCV70138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715540353330,"sku":"ZMSCV70138","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bcb30ea70f0b11da633d52783307f868.jpg?v=1788515377","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70138-viton-o-ring-dash-138","provider":"Voomi Supply","version":"1.0","type":"link"}
