Why Replace Your Gauge?

• Accuracy – Gauges lose accuracy over time due to wear and pressure cycling
• Readability – Faded scales or damaged faces reduce readability
• Safety – Damaged gauges can give false readings leading to system damage
• Compliance – Maintain calibration standards for professional work

Installation:

Simply unscrew the old gauge from your manifold body and replace with this gauge. Standard 1/8" NPT thread fits all Mastercool brass and aluminium manifolds. No special tools required.

Professional Quality: Mastercool gauges are manufactured to the highest standards with ANTI-FLUTTER technology for reliable, accurate readings in demanding HVAC/R service environments.
