The leaf measures 0.025 inches thick, 0.5 inches wide, and 12 inches long with a parallel profile that maintains consistent thickness along the full length. Machinists, HVAC technicians, and equipment service professionals use feeler gages like this one to verify valve clearances, set burner electrode gaps, check bearing fits, and confirm proper air gaps in motors and compressors. The tempered steel construction resists flex and wear under repeated use.\u003c\/p\u003e\n\u003cp\u003eThis feeler gage leaf is suited for both bench and field service work where gap measurement is required. Common applications include setting electrode gaps on ignition assemblies, checking valve train clearances on combustion equipment, verifying motor armature air gaps, and confirming tolerance fits during mechanical assembly. The 12-inch length provides reach into confined spaces without sacrificing rigidity. It is appropriate for residential and light commercial service environments across HVAC, refrigeration, plumbing equipment, and general mechanical trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eParallel leaf profile maintains uniform 0.025-inch thickness along the full 12-inch length\u003c\/li\u003e\n  \u003cli\u003eTempered steel construction for durability and resistance to deformation under repeated use\u003c\/li\u003e\n  \u003cli\u003e0.5-inch width provides a stable contact surface for accurate gap measurement\u003c\/li\u003e\n  \u003cli\u003e12-inch leaf length allows reach into recessed or confined service areas\u003c\/li\u003e\n  \u003cli\u003eSingle-leaf format for straightforward use without managing a multi-leaf set\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose feeler gage leaf suitable for gap and clearance measurement tasks across mechanical, HVAC, refrigeration, and combustion equipment service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFeeler gages are hand-measurement tools installed by technicians across the mechanical and HVAC trades. Power down or de-energize any equipment before inserting the gage leaf into a gap near moving or energized components. Slide the leaf into the gap with light, consistent force — a correct fit typically allows the leaf to pass with slight drag and no binding. Do not bend or force the leaf, as this can alter the calibrated thickness and compromise measurement accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.025 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: Tempered Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 52863\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540722811186,"sku":"52863","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7100b44097772943058972199a26b585.jpg?v=1785862969","url":"https:\/\/voomisupply.com\/products\/starrett-52863-feeler-gage-0-025-in-parallel-leaf-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
