The parallel leaf measures 12 inches long by 0.5 inches wide and is manufactured from high carbon steel for durability and dimensional stability. At 0.80mm thickness, this gage is suited for checking valve clearances, bearing fits, and component alignment tolerances. Licensed mechanics, HVAC technicians, and industrial maintenance professionals rely on this style of gage for repeatable, accurate feeler measurements in tight spaces where calipers or dial indicators cannot reach.\u003c\/p\u003e\u003cp\u003eThis feeler gage leaf is appropriate for use in both residential and commercial service environments. Common applications include checking clearances on furnace burner assemblies, compressor components, motor shaft alignments, and general mechanical assemblies where a specific gap must be confirmed before or after service. The 12-inch leaf length provides reach into deeper assemblies without requiring disassembly of surrounding components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.80mm leaf thickness for precise gap measurement\u003c\/li\u003e\n\u003cli\u003eParallel leaf style for consistent width along the full length\u003c\/li\u003e\n\u003cli\u003eHigh carbon steel construction resists bending and wear under repeated use\u003c\/li\u003e\n\u003cli\u003e12-inch leaf length provides extended reach into assemblies\u003c\/li\u003e\n\u003cli\u003e0.5-inch leaf width suits standard clearance-checking tasks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard parallel-leaf feeler gage suitable for general mechanical, HVAC, and industrial maintenance gap-measurement tasks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFeeler gages are used by HVAC technicians, machinists, and maintenance professionals to verify mechanical clearances. Always power down or de-energize equipment before inserting the gage leaf into any assembly. Apply light, consistent pressure when sliding the leaf into a gap — forcing the leaf can cause permanent deformation and compromise measurement accuracy. Keep the leaf clean and lightly oiled to prevent corrosion and maintain calibration integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.80mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeaf Style\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeaf Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeaf Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 91-411-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51696708419890,"sku":"91-411-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86e2e665d6e1a9479ad544e932e64ab9.jpg?v=1788345451","url":"https:\/\/voomisupply.com\/products\/spi-91-411-9-feeler-gage-0-80mm-parallel-leaf","provider":"Voomi Supply","version":"1.0","type":"link"}
