GallopMax HVAC AC Gauge Set — 4-Valve R1234yf/R134a/R404a Kit with Oil-Filled Gauges & Quick Couplers

GallopMax R1234YF R134a 4-valve AC gauge set is a ready-to-use HVAC charging and diagnostic kit built for modern refrigerants and professional daily use.

If you service vehicle or stationary air conditioning systems, you need a durable, accurate gauge set that handles multiple refrigerants without adapters or guesswork. This GallopMax kit supports R1234yf, R134a, and R404a and arrives complete with a 4-way manifold, four high-pressure hoses, quick couplers, can taps, and threaded adapters — everything required to measure pressure, evacuate lines, and recharge systems on both older and newer units.

How does this gauge set make HVAC service faster and safer?

The kit’s color-coded hoses and quick couplers reduce connection errors and speed up common procedures like vacuuming, pressure testing, and refrigerant addition. The oil-filled gauges stay readable in cold weather and resist shock, so you get consistent readings under workshop conditions.

• Four color-coded reinforced hoses for immediate identification
• Quick couplers for secure, leak-minimizing connections
• Oil-filled gauges for stable, fog-free readings in any temperature
• Complete fittings and can taps included — no extra purchases required

Is this set compatible with the refrigerants I commonly work with?

Yes — the GallopMax manifold and fittings are designed for cross-compatibility with R1234yf, R134a, and R404a systems. That flexibility allows technicians to switch between vehicle platforms and different HVAC appliances without swapping core tools.

• Supports R1234yf, R134a, and R404a refrigerants
• Threaded adapters to match varied service ports
• Self-sealing can taps for safe refrigerant draws

How accurate and durable are the gauges and hoses?

GallopMax uses oil-filled gauge movements and precision calibration screws to keep readings within ±1.6% on high/low pressure ranges. The manifold body is aluminum and fittings are pure copper, chosen to resist corrosion and heavy workshop wear.

• Oil-filled gauges for shock resistance and clear readings
• Aluminum manifold plus copper fittings for long-term durability
• 4-layer reinforced PVC hoses rated 800 psi working, 4000 psi burst

What comes in the box and what tasks can I perform immediately?

The kit ships complete and service-ready so technicians can begin diagnostics, evacuations, and refrigerant charging right away. Included accessories remove the need for aftermarket adapters in most common repair scenarios.

• 4-way gauge manifold with calibration screws
• Four heavy-duty, color-coded hoses with matching tips
• Two quick couplers, self-sealing can taps, and threaded adapters

Who is this for: The GallopMax R1234YF R134a 4-valve gauge set is aimed at automotive technicians, HVAC contractors, and experienced DIYers who need a professional, multi-refrigerant charging kit. It’s particularly useful for shops that service mixed fleets or handle both legacy and modern refrigerant systems and want a single, rugged toolset that delivers reliable readings and reduces downtime.
