## Long description

Feeler gauge Proline 21220 — single-pack precision gap measuring tool is a compact stainless steel blade for checking clearances and tolerances in mechanical assemblies. Supplied as one piece, this feeler gauge is designed to measure small distances between parts, helping to adjust valves, set spark plug gaps and verify clearances in engines and various machinery. The simple, durable design makes it suitable for workshop use and field service where a single, reliable thickness standard is needed.
Advantages
The stainless steel construction ensures corrosion resistance and a stable thickness over time, offering consistent measurement results. Its single-blade format provides straightforward handling and quick insertion into narrow gaps. The compact size and smooth edges reduce the risk of part damage during inspection and enable easy storage in a toolbox or pocket. Because it is a single, calibrated blade, it is easy to clean and maintain for repeated use.
Suitable for
Adjusting valve clearances on engines
Setting spark plug gaps
Measuring small gaps and tolerances in mechanical assemblies
Routine workshop inspections and maintenance tasks
Key specifications
Material: stainless steel
Pack: single piece
Use: precision gap measurement between mating parts
Form factor: flat blade for insertion into narrow spaces
Suitable environment: workshop and field service
How to use
Wipe the feeler gauge clean before use to remove oil or debris. Gently insert the blade between the mating surfaces to be measured and feel for a slight drag that indicates the correct clearance. If the blade passes freely, a thicker blade is required; if it cannot enter, use a thinner gauge. Use steady, even pressure and avoid bending the blade during measurement. After use, clean the blade and store it in a dry place to preserve its accuracy.
Usage recommendations
For accurate results, perform measurements at ambient temperature and ensure contact surfaces are free of contaminants. Use the Proline stainless steel feeler blade for single-thickness checks and combine with other calibrated gauges when cumulative thickness is required.
