GallopMax AC Oil Dye Injector Kit — R134A/R1234YF/R410A Compatible, 2 oz Metered Aluminum

This all-in-one injector kit is designed for HVAC technicians and DIYers who need a reliable method to add lubricant, fluorescent leak-detection dye, or performance additives to automotive and light-truck air-conditioning systems. It supports both common refrigerants and arrives with dedicated quick couplers, measuring tools and oil checkers so you can measure and deliver precise volumes without cross-contamination.

How does this injector work with different refrigerants?

The kit includes snap-on couplers made for R134A and R1234YF low-side service ports and works with systems using R410A-compatible oils or additives. Using the correct coupling prevents leaks and ensures a secure connection during injection. The injector forces fluid into the system via a threaded plunger and safety valve for controlled delivery.

• Snap-on R134A and R1234YF low-side quick couplers included.
• Threaded aluminum body with safety valve for controlled injection.
• Compatible for oil, fluorescent dye, and liquid additives.

How do I measure and inject the correct amount?

The injector body has a laser-engraved scale ranging from 1/4 oz (7.5 ml) to 2 oz (60 ml) to help you dose accurately. A clear measuring cup and oil checkers indicate current oil levels and the exact volume being added. Injection is performed with the plunger; twist the outer tube, open the valve, and turn the handle clockwise until the set volume is delivered.

• Laser-engraved scale for precise dosing from 7.5 ml to 60 ml.
• Included 2 oz measuring cup for pre-measurement of fluids.
• Oil checkers report system oil presence before and after service.

What functions can this kit perform during A/C service?

Beyond adding oil after component replacement, the injector can re-lubricate compressors, introduce fluorescent scanner fluid for leak detection, or add liquid performance additives. The multi-function design eliminates the need for separate tools for each task, saving time during routine maintenance and diagnostics. Each function uses the same secure coupling and injection technique to maintain system integrity.

• Add compressor oil or top up system lubricant after repairs.
• Inject fluorescent dye to locate leaks with UV scanners.
• Introduce compatible liquid additives to improve system function.

What comes in the kit and how is it used safely?

The GallopMax kit ships complete with a 2 oz injector, a pair of oil checkers, a 2 oz measuring cup and both R134A and R1234YF low-side couplers. Start the vehicle with A/C set to max cooling, attach the proper coupler to the low side, fill the injector to the measured volume, open the safety valve and turn the plunger to inject. Follow refrigerant-handling best practices: work in a ventilated area, wear gloves and eye protection, and avoid introducing incompatible fluids.

• Contents: 2 oz aluminum injector, 2 oil checkers, 2 oz cup, two quick couplers.
• Procedure: connect low-side, fill injector, open safety valve, screw plunger to inject.
• Safety: use PPE, ensure correct coupler, avoid contaminating refrigerant circuit.

Who is this for: The GallopMax injector kit is aimed at professional mechanics, mobile A/C technicians and experienced DIYers who service automotive air-conditioning systems and need a compact, accurate tool to add oil, dye or additives across R134A and R1234YF systems. It’s particularly useful for workshops that service multiple refrigerant types and want to avoid buying separate injectors for each system.
