Aluminum 4 Way R410 AC Manifold Gauge Set with Sight Glass 80MM

The Aluminum 4 Way R410 AC Manifold Gauge Set with Sight Glass 80MM (SKU: 9G4107) is a professional-grade HVAC refrigerant charging and diagnostic tool designed for air conditioning technicians and refrigeration specialists. This R410A manifold gauge set helps measure refrigerant pressure, perform vacuum checks, and support accurate AC system servicing.

Built with a durable aluminum body, this 4-way refrigerant manifold gauge provides excellent strength while remaining lightweight for easy handling during field operations. The integrated 80mm sight glass allows technicians to visually monitor refrigerant flow and charging conditions, improving service accuracy.

The set includes four 60-inch color-coded 5/16″ SAE hoses for convenient identification of high pressure, low pressure, vacuum, and charging connections. Equipped with clear pressure scales, this AC pressure testing gauge supports high-pressure R410 refrigerant applications with reliable readings.

This R410A charging manifold features a high-pressure range of 0–800 PSI (0–55 kg/cm²), low-pressure measurement from 0–500 PSI (-1–35 kg/cm²), and vacuum measurement up to 76 in/Hg, making it suitable for a wide range of air conditioning repair and maintenance tasks.

Designed for professional HVAC use, this refrigeration manifold gauge set provides accurate performance, easy operation, and long service life for technicians working on modern cooling systems.
