Precision Brand 19440 Steel Feeler Gauge 0.013 in

Product Description

The PRECISION BRAND 19440 is a single steel feeler gauge blade used to measure precise gaps, clearances, and tolerances in mechanical assemblies. The blade is 0.013 inches thick, 0.5 inches wide, and 12 inches long, ground and polished from high-carbon spring steel to maintain dimensional accuracy across its full length. Technicians in HVAC, plumbing, electrical, and general mechanical service rely on feeler gauge blades like this one to verify valve clearances, electrode gaps, and bearing fits during installation and maintenance work.

This feeler gauge blade is suited for residential and commercial service applications where precise gap measurement is required. Common use cases include checking spark electrode gap settings on gas burners and ignitors, measuring clearances on mechanical components during assembly or inspection, and verifying tolerances on motors and rotating equipment. The 12-inch blade length accommodates hard-to-reach locations in equipment cabinets and panels.

Key Features

• Blade thickness of 0.013 inches for accurate gap measurement
• Ground and polished high-carbon spring steel for consistent tolerance across the blade
• 0.5 inches wide by 12 inches long blade for extended reach
• Close-grain steel construction resists flex and maintains flatness during use
• Single-blade format for use as a standalone gauge or replacement in a set

Compatibility

Designed as a standard feeler gauge blade suitable for general mechanical gap and clearance measurement applications across HVAC, plumbing, and electrical service trades.

Installation Notes

Feeler gauge blades are used by trained technicians and require no tools for use. When checking gaps on energized equipment, de-energize and lock out the system before inserting the blade into any clearance. Do not force the blade into a gap smaller than its rated thickness, as this can bend the blade and affect measurement accuracy. Blades should be wiped clean and stored dry to prevent corrosion.
