The leaf measures 0.95 mm in thickness, 0.5 inches wide, and 12 inches long, giving technicians enough reach to access recessed measurement points without removing adjacent components. Constructed from high carbon steel, the leaf resists flex distortion and holds its nominal thickness under repeated use. This gauge is suited for HVAC technicians, machinists, engine mechanics, and service professionals who require accurate gap measurements during routine maintenance or equipment assembly.\u003c\/p\u003e\n\u003cp\u003eThis feeler gauge is used wherever precise gap measurement is required — burner orifice clearance checks, valve lash settings, bearing clearances, and component alignment in both residential and light commercial service applications. The 12-inch leaf length makes it practical in deep or partially obstructed assemblies where shorter gauges cannot reach. The parallel leaf style provides a consistent cross-section along the full length of the blade, ensuring repeatable measurement contact along the entire insertion depth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.95 mm nominal thickness for precise gap and clearance measurement\u003c\/li\u003e\n  \u003cli\u003eParallel leaf style maintains consistent cross-section along full 12-inch length\u003c\/li\u003e\n  \u003cli\u003eHigh carbon steel construction resists wear and maintains dimensional stability\u003c\/li\u003e\n  \u003cli\u003e0.5-inch blade width provides adequate contact surface for stable readings\u003c\/li\u003e\n  \u003cli\u003e12-inch length allows access to deep or partially enclosed measurement points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose parallel-leaf feeler gauge suitable for mechanical clearance measurement tasks across HVAC, engine service, and industrial maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFeeler gauges are a hand-measurement tool and do not require installation. Insert the leaf into the gap being measured without forcing or bending the blade, as permanent deformation will affect accuracy. Clean the blade before and after each use to prevent contamination from affecting measurement readings. Store gauges flat or in a protective case to maintain leaf straightness and prevent corrosion on the high carbon steel surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.95 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\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: 91-414-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689673949490,"sku":"91-414-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e391e81c300443dfaab19401fd7c0db.jpg?v=1788262795","url":"https:\/\/voomisupply.com\/products\/spi-91-414-3-feeler-gauge-parallel-leaf-0-95-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
