How does this kit prevent gauge damage on job sites?

The rubber boots act as a protective barrier around the instrument body, cushioning shocks from drops and blunt impacts. They reduce the chance of cracks or internal damage that can cause inaccurate readings or costly gauge replacement.

• Shock-absorbing rubber reduces impact force on the dial and housing.
• Oil- and scratch-resistant finish stands up to workshop conditions.
• Form-fitting design locks onto 3-1/8" Ye-llow Jacket gauge casings securely.

What improvement does the 49100 crystal lens provide to old or damaged gauges?

The 49100 lens restores clarity to scratched, fogged, or missing gauge faces so technicians can read dials accurately. Its optical transparency returns the instrument’s professional appearance and helps avoid misreads caused by distorted or obscured markings.

• High-clarity crystal restores unobstructed dial visibility.
• Precision fit for Ye-llow Jacket 3-1/8" gauges ensures proper alignment.
• Quick swap-in replacement minimizes downtime between jobs.
