The leaf measures 0.022 inches thick, 0.5 inches wide, and 12 inches long, providing enough reach for most service and assembly applications. Constructed from high carbon steel, the leaf resists wear and holds its calibrated thickness under repeated use. HVAC technicians, machinists, and general service trades use feeler gauges like this one to check valve clearances, set burner gaps, verify electrode spacing, and confirm fits during assembly or inspection work.\u003c\/p\u003e\u003cp\u003eThis gauge is suited for residential and light commercial service scenarios where precise gap measurement is required. Common applications include setting igniter-to-burner electrode gaps on gas appliances, checking clearances on mechanical assemblies, and verifying tolerances during preventive maintenance. The 12-inch leaf length allows access into recessed areas where shorter gauges cannot reach. The 0.5-inch width provides a stable contact surface across the measured gap.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eParallel leaf profile maintains consistent 0.022-inch thickness along the full 12-inch length\u003c\/li\u003e\n\u003cli\u003eHigh carbon steel construction resists bending and deformation during repeated use\u003c\/li\u003e\n\u003cli\u003e0.5-inch leaf width provides stable, flat contact across the measured gap\u003c\/li\u003e\n\u003cli\u003e12-inch length allows access to deep or recessed measurement points\u003c\/li\u003e\n\u003cli\u003eSingle-leaf format for straightforward, dedicated-thickness measurement tasks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose 0.022-inch feeler gauge suitable for HVAC, mechanical, and light industrial gap-measurement applications where a parallel-leaf profile is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFeeler gauges are used by HVAC technicians, mechanics, and service pros as a measurement tool, not an installed component. De-energize and shut off gas supply to any appliance before using a feeler gauge to set electrode or burner gaps. Insert the leaf gently and do not force it into tight clearances, as bending the leaf will compromise its calibrated thickness. Clean the leaf after each use and store it flat to preserve accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.022 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\u003eLeaf Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeaf Style\u003c\/strong\u003e: Parallel\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: 0.0356 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: 91-375-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692919423282,"sku":"91-375-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/acf7658fd259909730cc6aa0ce059168.jpg?v=1788304961","url":"https:\/\/voomisupply.com\/products\/spi-91-375-6-feeler-gauge-0-022-inch-parallel-leaf","provider":"Voomi Supply","version":"1.0","type":"link"}
