The Snap-on Manifold Gauge Set is a high-quality diagnostic tool designed for precision monitoring and servicing of automotive air conditioning systems. Built for technicians who demand reliability and accuracy, this set is engineered to handle both R-134a and R-1234yf refrigerants (depending on model), making it ideal for modern and legacy A/C systems.

Key Features:

• Durable Construction: Heavy-duty aluminum manifold body with solid brass fittings ensures long-lasting performance under demanding shop conditions.

• High-Accuracy Gauges: Easy-to-read, color-coded analog gauges for precise pressure readings during evacuation, charging, and testing.

• Color-Coded Hoses: Includes red (high pressure), blue (low pressure), and yellow (service) hoses with quick-connect couplers for fast and secure hookup.

• Built-in Sight Glass: Allows for visual monitoring of refrigerant flow to ensure accurate charging.

• Anti-Flutter Design: Shock-resistant gauge dampers provide smooth, stable needle movement for easier readings.
