It measures 2 inches inside diameter, 2.375 inches outside diameter, and 0.1875 inches thick. The X cross section provides four-point sealing contact, which reduces roll and spiral-out in dynamic applications compared to a standard round-section O-ring. NBR compound offers solid resistance to petroleum-based fluids, making this ring suitable for hydraulic, pneumatic, and fluid-handling assemblies. Plumbers, HVAC technicians, and industrial maintenance technicians commonly use Dash 329 O-rings as sealing elements in pipe fittings, valve bodies, and equipment flanges.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for static and dynamic sealing applications in residential and commercial systems where petroleum-based oil, fuel, or water is the working fluid. Typical installation points include pump housings, valve stems, union fittings, and threaded port plugs. The Dash 329 size is a standard AS568 designation, meaning it is a direct dimensional match for any AS568-329 gland. Sold in packages of 25, this SKU is appropriate for stocking service vans or shop inventory where multiple repairs of the same fitting size are anticipated.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eX-profile (Quattro) cross section provides four-point contact sealing, reducing O-ring roll and spiral failure in dynamic grooves\u003c\/li\u003e\n  \u003cli\u003eNitrile Butadiene Rubber (NBR) compound resists petroleum-based hydraulic fluids, oils, and water\u003c\/li\u003e\n  \u003cli\u003eDash 329 designation conforms to AS568 standard dimensions for direct gland compatibility\u003c\/li\u003e\n  \u003cli\u003e2 inches inside diameter and 0.1875 inches cross-section thickness suit medium-bore fittings and valve ports\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 25 supports fleet stocking and multi-unit repair jobs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard AS568 Dash 329 replacement O-ring for any gland or groove dimensioned to accept a 2 inches ID by 2.375 inches OD by 0.1875 inches thick X-profile seal in NBR material.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePower down or depressurize the system completely before removing any fitting or valve that retains this O-ring. Clean the gland groove of debris, old compound, and corrosion before seating the new ring. Apply a thin film of compatible lubricant to the O-ring and groove to prevent tearing during assembly. Verify the gland dimensions match the Dash 329 specification before installation to avoid under- or over-compression of the seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 329\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2 inches (2.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.375 inches (2.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: X (Quattro)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (NBR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401500\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: ZMSCQH70329\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702652109106,"sku":"ZMSCQH70329","price":28.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_08977db7-791b-42da-a737-48a98b7ec710.jpg?v=1788412548","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscqh70329-o-ring-dash-329-nbr-x-cross","provider":"Voomi Supply","version":"1.0","type":"link"}
