Precision Brand 77155 Thickness Gage 0.003 in Stainless Steel

Product Description

The PRECISION BRAND 77155 is a stainless steel thickness gage supplied in a continuous strip format measuring 0.003 inches thick, 0.5 inches wide, and 25 feet long. Thickness gages of this type are used to measure clearances, set gaps, and verify tolerances during assembly, alignment, and inspection tasks. The stainless steel construction resists corrosion and holds dimensional accuracy across a wide range of shop and field conditions. Technicians in HVAC, refrigeration, mechanical, and general maintenance trades reach for this type of gage when precise gap measurement is required and a rigid measuring instrument is not practical.

This gage strip is suited for applications where a flexible, conformable feeler stock is needed rather than a rigid blade set. Common uses include checking bearing clearances, verifying gasket compression gaps, setting valve clearances, and confirming component alignment during installation or service. The 25-foot roll format allows technicians to cut custom lengths to fit specific measurement tasks on the job or at a bench.

Key Features

• Stainless steel construction for corrosion resistance and long service life
• 0.003-inch thickness for fine-tolerance gap and clearance measurement
• 0.5-inch width provides a workable surface for most clearance checks
• 25-foot continuous roll allows custom-length pieces to be cut as needed
• Flexible strip format conforms to curved or irregular mating surfaces

Compatibility

Designed as a general-purpose thickness gage strip suitable for use in HVAC, refrigeration, mechanical maintenance, and light industrial service applications where 0.003-inch feeler stock is specified.

Installation Notes

This product is a measurement and layout tool, not an installed component. Power down or de-energize any equipment before using feeler stock to check internal clearances on motors, compressors, or electrical assemblies. Use appropriate cutting tools such as shears or snips to cut strip lengths cleanly and avoid burrs that could affect measurement accuracy. Discard sections that become kinked or deformed, as dimensional integrity is required for accurate readings.
