Precision Brand 19335 Feeler Gage 0.008 in Parallel Leaf

Product Description

The PRECISION BRAND 19335 is a parallel-leaf feeler gage manufactured from high carbon steel, designed for precise gap measurement in mechanical assembly, maintenance, and inspection work. The leaf measures 0.008 inches thick, 0.5 inches wide, and 12 inches long, providing a consistent and stable measuring surface along the full length of the blade. This type of feeler gage is a standard tool in HVAC, mechanical, and industrial trade work where accurate clearance checks on components such as valve seats, spark plugs, bearings, and machinery fits are required. Each package contains 12 individual leaves.

This feeler gage leaf is suited for use in residential and commercial maintenance environments, as well as light industrial settings. The parallel-leaf design delivers uniform thickness from end to end, making it appropriate for blind-clearance checks, go/no-go gap verification, and general fitment work. HVAC technicians, millwrights, and mechanics commonly use individual replacement leaves when a specific gauge thickness is needed without replacing an entire set.

Key Features

• Parallel leaf design provides uniform 0.008 inch thickness end to end
• High carbon steel construction for durability and resistance to deformation under load
• 12 inch leaf length accommodates a wide range of measurement applications
• 0.5 inch width provides stable surface contact during gap checks
• Metric equivalent thickness of 0.20 mm for dual-standard reference
• Sold in a package of 12 individual leaves

Compatibility

Designed as an OEM-style replacement leaf for use with standard feeler gage sets and holders that accept 12 inch parallel-style blades.

Installation Notes

Feeler gage leaves are used by hand and require no power tools or power disconnection during normal gap measurement. Handle leaves carefully to avoid bending, as deformation will compromise measurement accuracy. Clean the blade surface before use to remove oils or debris that could affect clearance readings. Replace any leaf that shows visible wear, pitting, or permanent deformation.
