It measures 3.125 inches inside diameter, 3.5 inches outside diameter, and 0.1875 inches thick with a round cross section. Shore hardness is rated at 70, placing it in the hard range. Rated for continuous service from -15 degrees F to 400 degrees F, this O-ring suits demanding sealing environments in HVAC, plumbing, hydraulic, and industrial systems. Licensed plumbers, HVAC technicians, and industrial mechanics are the typical end users. Each package contains 5 pieces.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for residential and commercial applications where contact with petroleum products, hydraulic fluids, and a wide spectrum of chemicals is expected. The fluoroelastomer compound delivers low compression set and low gas permeability, making it a reliable choice for vacuum service lines, high-temperature fluid connections, and fuel-system sealing points. It is also appropriate for use in pool and spa equipment where chemical-resistant sealing is required at larger-bore fittings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton) compound provides wide chemical compatibility including petroleum products\u003c\/li\u003e\n\u003cli\u003eOperating range of -15 degrees F to 400 degrees F for high-temperature service\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness (hard rating) for low compression set under sustained load\u003c\/li\u003e\n\u003cli\u003eLow gas permeability makes it suitable for vacuum service applications\u003c\/li\u003e\n\u003cli\u003eRound cross section for consistent seating in standard O-ring grooves\u003c\/li\u003e\n\u003cli\u003eSold in a 5-piece package with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Dash 338 standard O-ring replacement for any groove or port sized to accept a 3.125-inch ID, 3.5-inch OD, 0.1875-inch thick round cross-section seal.

De-pressurize and de-energize the system before removing the old seal, and inspect the groove for nicks or debris before seating the new O-ring. Lubricate the O-ring with a compatible fluid prior to installation to prevent tearing during assembly. Avoid using petroleum-based lubricants in systems where they are not compatible with other sealing materials present.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer (Viton)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A (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\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible With\u003c\/strong\u003e: Petroleum Products\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: 5 pieces\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: ZMSCV70338\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692130926898,"sku":"ZMSCV70338","price":23.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ea2cf2e1a5bd14faee74434e8e615aac.jpg?v=1788293517","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70338-viton-o-ring-dash-338","provider":"Voomi Supply","version":"1.0","type":"link"}
