It measures 0.452 inches inside diameter, 0.625 inches outside diameter, and 0.047 inches thick, with a rectangular cross-section profile. The durometer rating of 55 (medium hardness) provides a reliable static or low-motion seal across a wide service temperature range of -65 to 500 degrees F. Licensed plumbers, HVAC technicians, and industrial maintenance mechanics use this O-ring where standard nitrile or EPDM compounds are inadequate due to chemical exposure or extreme temperature.\u003c\/p\u003e\u003cp\u003eThis PTFE O-ring is suited for use in fluid handling systems, chemical process lines, high-temperature pneumatic fittings, and specialty HVAC refrigerant circuits where fluoropolymer material is specified. The Dash 111 designation follows AS568 standard sizing, making it a drop-in dimensional fit for any application calling out a Dash 111 O-ring groove. Sold in a package of 50 units, this SKU is appropriate for shop stock, service van inventory, or low-volume production use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePTFE construction resists chemical attack from acids, solvents, and aggressive process fluids\u003c\/li\u003e\n\u003cli\u003eWide operating temperature range: -65 to 500 degrees F\u003c\/li\u003e\n\u003cli\u003eDash 111 AS568-standard sizing: 0.452 inches ID x 0.625 inches OD x 0.047 inches thick\u003c\/li\u003e\n\u003cli\u003eMedium durometer hardness (55) for consistent static sealing performance\u003c\/li\u003e\n\u003cli\u003eRectangular cross-section for predictable groove fit and compression\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 50 supports shop stock and repeat-service applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to fit any application specifying an AS568 Dash 111 O-ring groove, including plumbing, pneumatic, chemical, and high-temperature HVAC fittings and valves requiring PTFE sealing material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eO-ring installation should be performed with the system fully depressurized and, where applicable, power or fuel supply shut off and locked out. Inspect the groove and mating surfaces for burrs or scoring before seating the ring. PTFE O-rings do not require lubrication in most chemical applications, but a compatible PTFE-rated grease may be used if assembly requires it. Follow applicable plumbing or mechanical codes for the jurisdiction when replacing seals in pressurized systems.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 111\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.452 inches (11.48 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.625 inches (15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.047 inches (1.19 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness (Durometer)\u003c\/strong\u003e: 55 (Medium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -65 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 500 degrees F\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: 0.05 pounds\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: ZMSCTST111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711852052786,"sku":"ZMSCTST111","price":24.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30b4cf84e8413a0ccc2591328d901348_b036edf9-cad7-42b1-9bd7-50fbcc27a7fe.jpg?v=1788480462","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsctst111-ptfe-o-ring-dash-111-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
