The leaf measures 0.002 inches thick, 0.5 inches wide, and 12 inches long, with a parallel profile that maintains consistent thickness across the full length of the blade. Constructed from high carbon steel, the blade resists wear and holds its calibrated thickness under repeated use. Technicians rely on this type of gage when setting valve clearances, checking bearing fits, verifying gasket compressions, or confirming tolerances during equipment assembly and inspection.\u003c\/p\u003e\n\u003cp\u003eThis feeler gage is suited for use in HVAC, refrigeration, plumbing, and general mechanical service environments where precise gap measurement is required. The 12-inch blade length provides reach into confined spaces without sacrificing rigidity. Parallel leaf geometry ensures the same measurement is taken regardless of insertion depth, making it appropriate for consistent field and shop use by licensed technicians and trained mechanics.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.002-inch blade thickness for fine-tolerance gap measurement\u003c\/li\u003e\n  \u003cli\u003eParallel leaf style maintains uniform thickness along the full 12-inch length\u003c\/li\u003e\n  \u003cli\u003eHigh carbon steel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e0.5-inch blade width provides a stable contact surface during measurement\u003c\/li\u003e\n  \u003cli\u003eSingle-leaf format for straightforward, no-assembly use in the field\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard parallel-leaf feeler gage suitable for general mechanical clearance measurement applications across HVAC, refrigeration, and industrial maintenance trades.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFeeler gages are used by mechanics, HVAC technicians, and millwrights as a measurement tool, not a permanently installed component. Always power down and de-energize equipment before inserting a feeler gage into any rotating or energized assembly. Keep blades clean and free of oil or debris that could affect measurement accuracy. Avoid bending or flexing the blade beyond its natural profile, as deformation will compromise calibrated thickness.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\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: 0.0034 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 91-354-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51722418061618,"sku":"91-354-1","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08fde29cfbe770ff6908a47b88c94fe5.jpg?v=1788590853","url":"https:\/\/voomisupply.com\/products\/spi-91-354-1-feeler-gage-0-002-in-parallel-leaf-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
