Precision Brand 19530 Feeler Gage 0.017 in Parallel Leaf

Product Description

The PRECISION BRAND 19530 is a parallel-leaf feeler gage used to measure gap clearances with consistent accuracy. The leaf is 0.017 inches thick, 0.5 inches wide, and 12 inches long, providing a generous reach for checking tight tolerances in confined spaces. Constructed from high carbon steel, this gage delivers the rigidity and wear resistance required for repeated use in shop and field environments. Machinists, HVAC technicians, and maintenance professionals use feeler gages to verify valve clearances, bearing fits, and component alignment during assembly or service work.

This feeler gage is suited for residential and commercial maintenance applications where precise gap measurement is required. The parallel leaf style keeps the width uniform along the full 12-inch length, making it practical for straight-line clearance checks on flat surfaces, flanged joints, and machine components. It is commonly used during HVAC equipment installation and preventive maintenance procedures where component spacing must meet manufacturer tolerances.

Key Features

• Leaf thickness of 0.017 inches (0.43 mm) for precise gap measurement
• Parallel leaf style maintains uniform 0.5-inch width across the full 12-inch length
• High carbon steel construction provides rigidity and resistance to wear and deformation
• 12-inch length allows reach into recessed or confined clearance points
• Package quantity of 12 leaves supports stocking multiple thicknesses or replacing worn gages

Compatibility

Designed as a standard parallel-leaf feeler gage for general maintenance and mechanical service applications requiring a 0.017-inch gap measurement leaf.

Installation Notes

Feeler gages are installed by licensed HVAC technicians, machinists, and maintenance trades during equipment service or assembly. Always de-energize and lock out equipment before inserting a feeler gage into any rotating or pressurized assembly. Insert the leaf smoothly without forcing it; bending or kinking the leaf will affect measurement accuracy. Handle high carbon steel gages with clean, dry hands or light oil to prevent corrosion from moisture exposure.
