Precision Brand 19255 Feeler Gage 0.005 in 5 in 10 Leaves

Product Description

The PRECISION BRAND 19255 is a flat-leaf feeler gage used to measure precise clearances and gaps in mechanical assemblies. Each leaf measures 0.005 inches thick and 5 inches long, making it suited for checking tight tolerances in engine components, bearing fits, valve clearances, and machined mating surfaces. The set includes 10 leaves, all constructed from high-carbon steel for durability and consistent spring-back. HVAC technicians, millwrights, machinists, and general maintenance professionals use feeler gages like the 19255 to verify air gaps, set igniter clearances, and confirm proper component spacing during installation or service.

The 19255 is appropriate for both shop and field use wherever a 5-inch flat-leaf gage at 0.005-inch thickness is required. Common applications include checking spark plug gaps, burner igniter gaps on gas appliances, compressor valve clearances, and motor bearing end play. The 0.5-inch leaf width provides a practical contact surface for most standard gap-check tasks. Individual leaves can be used alone or stacked with other gage leaves to measure cumulative clearances.

Key Features

• Flat leaf style for straightforward gap and clearance measurement
• 0.005-inch (0.127 mm) leaf thickness for fine tolerance checks
• 5-inch (127 mm) leaf length provides reach into recessed clearances
• 0.5-inch (12.7 mm) leaf width gives stable contact on mating surfaces
• High-carbon steel construction for rigidity and long service life
• 10 leaves per package for replacement stock or multi-tech tool kits

Compatibility

Designed as a standard flat-leaf feeler gage for general mechanical, HVAC, and industrial maintenance applications requiring a 0.005-inch measurement leaf.

Installation Notes

Feeler gages are precision measuring tools and do not require installation in the traditional sense. Before use, clean both the gage leaf and the surfaces being measured to remove debris that could affect accuracy. Insert the leaf with light drag resistance as the standard indication of correct fit — forcing the leaf can bend or distort it. Store leaves flat and avoid dropping the set, as impacts can alter leaf geometry and measurement accuracy.
