The leaf measures 0.5 inches wide by 12 inches long with a parallel profile and a nominal thickness of 0.05 millimeters. Constructed from high carbon steel, the blade resists wear and maintains dimensional accuracy through repeated use. HVAC technicians, machinists, and maintenance professionals use feeler gages to check valve clearances, spark plug gaps, bearing tolerances, and burner orifice spacing. The 12-inch leaf length provides reach into confined assemblies without bending.\u003c\/p\u003e\u003cp\u003eThis feeler gage leaf is suited for residential and commercial maintenance work where a single specific thickness is needed for a dedicated setup task. It is commonly used on gas appliance burner assemblies, compressor valves, motor end-play checks, and general mechanical clearance verification. The parallel leaf style delivers consistent width along the full length of the blade, which is important when a uniform contact surface is required across the measurement point.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eParallel leaf profile provides consistent 0.5-inch width along the full 12-inch blade length\u003c\/li\u003e\n\u003cli\u003e0.05 mm nominal thickness for fine-clearance measurement work\u003c\/li\u003e\n\u003cli\u003eHigh carbon steel construction for durability and dimensional stability\u003c\/li\u003e\n\u003cli\u003e12-inch length allows reach into deep or restricted assemblies\u003c\/li\u003e\n\u003cli\u003eSingle-leaf format suits dedicated clearance setups and go\/no-go checking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard single-leaf feeler gage for use wherever a 0.05 mm parallel-style blade is required in mechanical, HVAC, or general maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFeeler gages are precision measurement tools installed or used by HVAC technicians, machinists, and qualified maintenance personnel. Always power down and de-energize equipment before inserting a feeler gage into any moving assembly or energized component area. Do not force the blade into a gap; apply light, even pressure to avoid bending the leaf and introducing measurement error. Keep blades clean and lightly oiled when stored to prevent corrosion that can alter blade thickness.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.05 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeaf Style\u003c\/strong\u003e: Parallel\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\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\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 91-392-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692574802226,"sku":"91-392-1","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9ff3d6df5e99b5f8ace1bcd4d6a0d25.jpg?v=1788299560","url":"https:\/\/voomisupply.com\/products\/spi-91-392-1-feeler-gage-parallel-leaf-0-05mm","provider":"Voomi Supply","version":"1.0","type":"link"}
