It measures 1.375 inches inside diameter, 1.75 inches outside diameter, and 0.1875 inches (3\/16 inches) thick. With a Shore A hardness rating of 70, this O-ring delivers firm compression set resistance along with excellent tear and abrasion resistance. It is compatible with petroleum-based fluids, making it the most widely used general-purpose elastomer in industrial and mechanical sealing work. Licensed HVAC technicians, plumbers, and mechanical contractors routinely specify this size for valve, fitting, and pump seal applications.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for sealing duties in residential and commercial mechanical systems where petroleum-based lubricants, hydraulic oils, fuels, or similar media are present. It performs reliably across a temperature range of -40 degrees F to 250 degrees F, covering most heating, cooling, plumbing, and fluid-power service conditions. The round cross-section profile seats cleanly in standard AN\/SAE Dash 324 O-ring grooves. Sold in a package quantity of 50 units, it is a practical bench-stock item for service shops and field technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (nitrile butadiene rubber) construction — the most widely used O-ring elastomer for petroleum service\u003c\/li\u003e\n  \u003cli\u003eShore A 70 durometer hardness — rated Hard, providing strong compression set and extrusion resistance\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eExcellent resistance to petroleum products, hydraulic oils, and fuels\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile for consistent seating in standard Dash 324 grooves\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 50 — suitable for shop stock or multi-unit service jobs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application calling for a standard Dash 324 O-ring groove; compatible with petroleum products and petroleum-based fluids.

Always depressurize and drain the affected line or component before removing the old O-ring. Lightly lubricate the O-ring with a compatible petroleum-based grease before seating to prevent pinching or rolling during assembly. Do not store unused O-rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure degrade nitrile rubber over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.375 inches (1-3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.75 inches (1-3\/4 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\u003eDash Number\u003c\/strong\u003e: 324\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 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: -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 Media\u003c\/strong\u003e: Petroleum Products\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: 50\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\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: ZMSCH70324\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696633413938,"sku":"ZMSCH70324","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6566c1749878217bacd0534985c2ad9.jpg?v=1788344681","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70324-o-ring-dash-324-nitrile-70a","provider":"Voomi Supply","version":"1.0","type":"link"}
