Precision Brand 19330 Flat Feeler Gage 0.008 in 10 Pack

Product Description

The PRECISION BRAND 19330 is a flat feeler gage leaf used to measure precise clearances and gaps in mechanical assemblies. Each leaf is made from high-carbon steel and measures 0.008 inches (0.203 mm) thick, 5 inches long, and 0.5 inches wide. This package contains 10 leaves of identical thickness. Feeler gages of this type are a standard diagnostic and setup tool used by machinists, HVAC technicians, engine mechanics, and millwrights when verifying valve clearances, bearing fits, shaft alignments, and other tight-tolerance gaps.

The 19330 flat leaf style suits a wide range of close-clearance measurement tasks in both residential and commercial service settings. Common applications include spark plug gap checks, valve lash adjustment on gas-fired equipment, rooftop unit fan blade tip clearance verification, and precision machine setup. The 5-inch leaf length provides enough reach for most standard service access points without excess flex. Supplied in a 10-pack, these leaves work as replacements for worn or bent leaves in existing feeler gage sets or as dedicated single-thickness tools staged in a service kit.

Key Features

• 0.008 inch (0.203 mm) thickness for precise gap measurement at that tolerance
• Flat leaf style for straightforward insertion into parallel gap applications
• High-carbon steel construction for durability and resistance to deformation
• 5 inch leaf length with 0.5 inch width for good reach and handling
• 10 leaves per package — suitable for stocking or replacing individual gage set leaves

Compatibility

Designed as standard flat feeler gage leaves compatible with typical multi-leaf feeler gage holders and used as standalone gap-measurement tools across mechanical, HVAC, and engine service applications.

Installation Notes

Feeler gages are hand tools and require no power-down procedure for the gage itself, though the equipment being measured must be shut down and de-energized or depressurized per applicable safety procedures before inserting the leaf. Insert the leaf with light, even pressure — forcing a leaf can bend or score it and introduce measurement error. Replace any leaf that shows visible kinks, scoring, or corrosion, as surface damage affects accuracy.
