The leaf measures 0.013 inches thick, 0.5 inches wide, and 12 inches long, giving technicians a full-length reach into tight clearances. Constructed from high carbon steel, the leaf resists flex distortion and maintains dimensional accuracy through repeated use. This gauge is used by HVAC technicians, machinists, and field service pros who need consistent gap verification during alignment, adjustment, or inspection tasks.\u003c\/p\u003e\u003cp\u003eThis feeler gauge leaf is suited for residential and commercial service applications where gap measurement is required. Common uses include checking valve clearances, burner orifice gaps, motor shaft alignment tolerances, and compressor component clearances. The 12-inch length allows access to recessed or hard-to-reach measurement points without repositioning. The parallel leaf style delivers uniform thickness across the full length, which is critical for accurate readings in flat-surface gap applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eParallel leaf style ensures consistent 0.013-inch thickness along the full 12-inch length\u003c\/li\u003e\n\u003cli\u003eHigh carbon steel construction resists bending and maintains long-term dimensional accuracy\u003c\/li\u003e\n\u003cli\u003e0.5-inch width provides stable contact surface for reliable gap measurement\u003c\/li\u003e\n\u003cli\u003e12-inch length reaches deep into assemblies and tight clearance points\u003c\/li\u003e\n\u003cli\u003eSingle-leaf format for direct selection without flipping through a set\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose parallel feeler gauge leaf suitable for use in HVAC, mechanical, and equipment service applications requiring 0.013-inch gap measurement.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFeeler gauges are installed and removed by hand without special tools. Always power down or de-energize equipment and relieve any mechanical tension before inserting a gauge leaf into a clearance gap. Do not force the leaf into a gap smaller than the rated thickness, as this can deform the leaf and compromise measurement accuracy. Clean the gauge and contact surfaces before use to prevent debris from affecting readings.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.013 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: 0.0223 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: 91-366-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51708641149234,"sku":"91-366-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e5ce0e8306ed2fa92925f099f4076e1.jpg?v=1788447574","url":"https:\/\/voomisupply.com\/products\/spi-91-366-5-feeler-gauge-0-013-in-parallel-leaf-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
