GallopMax AC Oil & Dye Injector Kit for R134A & R1234YF — 2oz Aluminium Injector, Snap-On Couplers

This injector kit streamlines oil service and leak-detection prep for modern automotive A/C systems. Built for technicians and advanced DIYers, the kit includes snap-on couplings for both refrigerants, a precision-measured aluminum injector body, and accessories to verify and control dosages. Clear laser-etched markings, a low-side valve design, and visual oil-check tools make it easy to add the right amount of oil or fluorescent dye without disassembling the system.

How does the GallopMax injector save time during A/C service?

The injector is engineered to feed oil or dye into the system while the compressor runs, avoiding lengthy system breakdowns. A twist-action plunger forces contents through a low-side check valve for efficient transfer and minimal mess.

• Snap-on R134A and R1234YF couplers for quick connection
• Push-twist plunger injection reduces manual pumping
• Works with POE or mineral oils and fluorescent scanner fluids
• Compact aluminum body fits workshop workflows

What volumes and accuracy can I expect when measuring oil or dye?

GallopMax supplies a 2 oz (60 ml) injector with laser-engraved graduations and a 2 oz measuring cup so you can dose reliably. The included oil checkers indicate existing oil level and the cup confirms added volume, helping avoid overfill or underfill.

• Capacity range: 1/4 oz (7.5 ml) to 2 oz (60 ml)
• Clear, laser-etched scale for visible measurements
• Oil checkers provide quick level feedback
• Measuring cup for precise pre-fill measuring

Can this kit handle both R134A and R1234YF systems safely?

Yes — the kit contains dedicated quick couplers for each refrigerant type so you can service different vehicles without swapping tools. Each coupler includes a valve to control flow and to ensure a secure, leak-resistant connection to the low-pressure port.

• Separate R134A and R1234YF snap-on low-side couplings
• Integrated safety/stop valve on couplers for controlled injection
• Designed to fit industry-standard low-side service ports
• Avoids cross-connection by using distinct fittings for each gas

What accessories are included and how do they support maintenance tasks?

The kit provides the primary injector plus tools that make dosing and leak-prep straightforward. Everything needed for typical oil or dye additions is included so you don’t need separate measuring or adapter pieces.

• 1 × 2 oz professional-grade aluminum oil and paint injector
• 1 × R1234YF low-side quick coupler with valve
• 1 × R134A low-side quick coupler with valve
• 2 × oil checkers and 1 × 2 oz measuring cup plus instructions

Who this is for: The GallopMax injector kit is aimed at professional service technicians, mobile A/C specialists, and experienced DIYers who work on multiple vehicle refrigerant types. If you need a compact, accurate way to add POE or mineral oil, inject fluorescent leak dye, or top up additives without removing major components, this kit provides the fittings and measuring tools to do the job efficiently. It is not a replacement for full-system diagnostics or certified refrigerant handling equipment; follow local regulations for refrigerant service and wear appropriate protective gear while working on pressurized systems.
