Mastercool 93500-G Gauge Anti-Flutter Device for HVAC Manifold Gauges

The Mastercool 93500-G Gauge Anti-Flutter Device is designed to eliminate needle flutter and vibration in HVAC manifold gauge sets, providing stable and accurate pressure readings. This essential diagnostic accessory helps technicians obtain precise measurements when working with refrigeration and air conditioning systems by dampening rapid needle oscillations caused by system pulsations.

Key Features:

• Eliminates gauge needle flutter for more accurate pressure readings
• Compatible with standard HVAC manifold gauge sets
• Easy installation with no special tools required
• Durable construction for long-lasting performance
• Improves diagnostic accuracy by stabilizing gauge needle movement

Ideal for HVAC technicians and refrigeration professionals who need consistent, reliable gauge readings during system diagnosis, charging, and recovery operations. The anti-flutter device installs between the manifold and the gauge to dampen pressure fluctuations without affecting measurement accuracy.
