With a 0.5000-inch inside diameter, 0.6880-inch outside diameter, and 0.0937-inch thickness, this Dash 112 O-ring fits standard groove dimensions for that dash size. PTFE material provides near-universal chemical inertness, low friction, and zero water absorption, making it a reliable choice where rubber elastomers would degrade. It is rated for service from -300 degrees F to 500 degrees F. Plumbers, HVAC technicians, and industrial maintenance professionals install these in valve seats, fittings, and fluid system connections.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial plumbing, HVAC refrigerant circuits, chemical fluid handling lines, and pneumatic systems where aggressive media or extreme temperatures rule out standard nitrile or EPDM seals. PTFE compounds are commonly specified when system fluids include strong acids, solvents, or oxidizers. The Dash 112 designation indicates a standardized size recognized across fluid power and plumbing industries, simplifying cross-referencing during maintenance and repair. These O-rings ship in a package quantity of 100, making them practical for shop stock or service van inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePTFE construction offers chemical inertness across a broad range of aggressive media\u003c\/li\u003e\n  \u003cli\u003eRated from -300 degrees F to 500 degrees F for extreme temperature service\u003c\/li\u003e\n  \u003cli\u003eDash 112 standard sizing for straightforward cross-referencing and replacement\u003c\/li\u003e\n  \u003cli\u003eRound cross section for consistent seating in standard O-ring grooves\u003c\/li\u003e\n  \u003cli\u003eMedium hardness rating (Shore 55) balances flexibility and compression resistance\u003c\/li\u003e\n  \u003cli\u003ePackage of 100 units supports shop stock and multi-unit service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement O-ring for any application requiring a Dash 112 round cross-section seal in PTFE material, including valve bodies, fittings, and fluid system components machined to Dash 112 groove specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eO-ring installation should be performed by a qualified plumber, HVAC technician, or pipefitter following applicable codes such as the IPC or IFGC. Shut off and depressurize the system fully before removing the old seal and inspecting the groove for damage or contamination. Avoid stretching the O-ring beyond its natural diameter during installation, and do not use petroleum-based lubricants with PTFE seals; use a compatible assembly lubricant if needed. Confirm groove dimensions match Dash 112 specifications before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PTFE (Polytetrafluoroethylene)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 112\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.6880 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 inches\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: 55 Shore (Medium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -300 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\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100\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: ZMSCTFE112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698486444338,"sku":"ZMSCTFE112","price":65.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc6bfb6f35a0485944da884a2ddc5632.jpg?v=1788363622","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsctfe112-ptfe-o-ring-dash-112-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
