GallopMax R1234YF & R134A AC Oil Dye Injector Kit — Dual Couplers, Precision 60ml Measuring Injector

This compact injector kit is built for technicians and DIYers who need a reliable way to add precise volumes of oil or fluorescent solutions into vehicle air-conditioning systems without evacuating refrigerant or swapping multiple tools. Designed to work with modern refrigerants, the kit includes dedicated snap-on couplers for both R134A and R1234YF low-side ports, graduated measuring capacity, and simple mechanical operation to force fluids into the system safely and predictably.

How does the injector actually deliver oil into an A/C system?

The injector uses a screw-plunger mechanism inside an aluminum body that pressurizes and forces oil or dye through a low-side check valve into the system while the compressor circulates refrigerant. It connects to the low-side service port so fluid travels with the system refrigerant rather than requiring system depressurization.

• Attach the appropriate snap-on quick coupler (R134A or R1234YF) to the vehicle low-side port.
• Fill the injector reservoir with the measured fluid and start the A/C system to circulate refrigerant.
• Open the safety valve and screw the plunger to push the fluid into the system.
• Laser-engraved scale and included measuring cup keep injected volumes accurate.

Which refrigerant systems and fluids is this kit compatible with?

The GallopMax kit is made to work with both R134A and R1234YF service ports and accepts POE or mineral oils, fluorescent leak solution, and most A/C system additives. Included couplers eliminate the need for separate tools when switching between refrigerant types.

• Included R134A and R1234YF snap-on low-side couplers with integrated valves.
• Accepts POE and mineral oils commonly used in automotive A/C service.
• Suitable for adding scanner fluorescent dye to help locate leaks under UV inspection.
• Not intended for refrigerant charging; use only for oils, dyes, and additives.

How much fluid can I measure and inject, and how accurate is it?

The injector has a clear, laser-engraved scale and ships with a 2 oz (60 ml) measuring cup so you can dose small to moderate amounts precisely. The internal capacity ranges from 1/4 oz (7.5 ml) up to 2 oz (60 ml), letting you match the manufacturer-recommended oil additions or dye quantities without guesswork.

• Graduated scale for precise readout of injected volumes.
• Oil checkers included to verify existing system oil level before topping up.
• 2 oz measuring cup for pre-measuring before transfer to the injector body.
• Aluminum construction resists corrosion and provides consistent mechanical action.

What comes in the box and how do I get started safely?

The kit is supplied ready for service: a 2 oz injector, both refrigerant couplers, two oil checkers, a 2 oz measuring cup and an instruction manual. To use it safely, read the included instructions, ensure the vehicle A/C is running with maximum cooling, and always connect to the low-side service port with the matching coupler.

• 1 professional-grade 2 oz aluminum oil/dye injector.
• 1 R1234YF quick coupler with valve and 1 R134A quick coupler with valve.
• 2 oil checkers, a 2 oz measuring cup, and user manual.
• Operate with A/C running on max to circulate added fluid into the system properly.

Who is this for: The GallopMax injector kit is aimed at automotive technicians, service shops, and knowledgeable DIY enthusiasts who need a durable, accurate tool to add oil, fluorescent dye, or compatible additives to R134A and R1234YF A/C systems. It’s not a refrigerant charging device; instead it simplifies oil/dye topping and diagnostic dye injection for leak detection, maintenance, and post-compressor service.
