Works Right Out of the Box: Gallopmax's complete AC gauge kit includes a 4-way gauge, four heavy-duty hoses, two quick couplers, self-sealing can taps, and threaded adapters. No extra parts needed – start servicing HVAC systems immediately.
Durability Meets Daily Use: Aluminum body and pure copper fittings resist corrosion, leaks, and wear. Engineered to outlast cheaper brass sets – survive drops, weather, and heavy workshop abuse for years.
Color-Coded Hoses Built to Withstand Extreme Pressure:4-layer reinforced PVC hoses (800 psi working/4000 psi burst) use color-coded tips. Swap connections faster and safer with zero guesswork.
Oil-Filled Precision for Year-Round Accuracy: Durable oil-filled gauges resist shock and cold-weather fogging. Calibration screws ensure ±1.6% accuracy on high/low pressure readings, backed by rugged dry-dial tech for reliable winter performance.
