Starrett 71256 Drop Indicator Rubber Dust Guard

Product Description

The STARRETT 71256 is a replacement rubber dust guard designed for use with AGD (American Gage Design) drop indicators. This protective accessory seals out debris, particulates, and contaminants that can interfere with indicator movement and accuracy over time. It fits around the indicator body to maintain a clean internal environment, helping preserve measurement repeatability in shop and field conditions. Machinists, tool and die makers, and quality control technicians typically service or replace this component during routine indicator maintenance.

This dust guard is suited for use in manufacturing environments, machine shops, and metrology settings where drop indicators are regularly deployed on magnetic bases, surface plates, or transfer setups. It is a direct replacement part intended to restore a worn or damaged seal on an existing AGD-style drop indicator without requiring full instrument replacement.

Key Features

• Rubber construction provides flexible, durable sealing against dust and debris
• Designed specifically for AGD drop indicators for proper fitment
• Simple replacement part that extends service life of the indicator
• Sold individually — one dust guard per package

Compatibility

Designed for use with AGD (American Gage Design) drop indicators as specified by the manufacturer.

Installation Notes

Installation of this dust guard is typically performed by a machinist or calibration technician during indicator inspection or rebuild. Ensure the indicator is removed from service and cleaned before fitting the new guard. Avoid stretching the rubber excessively during installation to prevent tearing or premature failure.
