Precision Brand 19K2X Feeler Gage Set 0.0025 Inch 12 Leaf

Product Description

The PRECISION BRAND 19K2X is a flat-leaf feeler gage set used to measure small gaps, clearances, and tolerances in mechanical assemblies. Each leaf measures 0.0025 inches thick, 0.5 inches wide, and 12 inches long, providing extended reach for hard-to-access measurement points. The set includes 12 leaves made from high-carbon steel for durability and dimensional stability under repeated use. Machinists, millwrights, engine rebuilders, and HVAC technicians rely on feeler gages like this to verify air gaps, valve clearances, bearing fits, and component alignment during installation and service.

This feeler gage set is suited for both shop and field use where precise gap measurement is required. The flat leaf style makes it compatible with standard gap-checking tasks on motors, compressors, pumps, generators, and other rotating or reciprocating equipment. The 12-inch leaf length allows access to recessed or deep-set clearance points that shorter gages cannot reach. This set is appropriate for light industrial, commercial maintenance, and residential trade applications.

Key Features

• Leaf thickness of 0.0025 inches for fine-tolerance gap measurement
• Flat leaf style for straightforward insertion into parallel gaps
• 12-inch leaf length provides extended reach in tight assemblies
• 0.5-inch leaf width offers a stable contact surface for accurate readings
• High-carbon steel construction resists deformation and maintains calibration over time
• 12-leaf set covers a range of measurement tasks from a single kit

Compatibility

Designed as a general-purpose feeler gage set suitable for gap and clearance measurement on a wide range of mechanical, HVAC, and industrial equipment where 0.0025-inch tolerance verification is required.

Installation Notes

Feeler gages are a hand measurement tool and require no installation. De-energize and lock out any equipment before inserting leaves into rotating machinery or live assemblies. Insert the leaf with light, consistent hand pressure — do not force or bend the leaf, as this will affect accuracy. Store leaves clean and lightly oiled to prevent corrosion and maintain dimensional accuracy.
