SURIEEN AC Dye Injector Kit R134A 2 oz Oil & Dye Injector — Aluminum Body, Low-Side Snap Coupler

The SURIEEN AC Dye Injector Kit is a handheld 2 oz oil and fluorescent dye injector designed to add lubricant or tracer dye into R134A, R410A, R22 and R12 refrigeration systems without relying on the compressor.

This compact aluminum-and-brass tool gives technicians and DIYers a controlled, compressor-independent method to introduce POE or mineral oil and leak-detecting fluorescent dye into low-side ports. Built for field use, the kit features a quick-snap low-side coupler, 1/4" SAE connection, and a 2-ounce push-in cylinder so you can meter lubricant and dye into systems for maintenance, diagnostics, or recovery from low-oil conditions.

How does the SURIEEN injector add oil or dye without running the compressor?

The injector uses a precharged inner cylinder and a simple push-turn valve to force oil or dye into the low-pressure side of the system. Because it seals to the low-side service port and relies on manual pressure rather than the running compressor, the tool is safe for adding measured amounts while the system is off.

• 2 oz (60 ml) push-type reservoir for controlled dosing
• Low-side 13 mm snap-on coupler for leak-free connection
• 1/4" SAE threaded fittings for standard compatibility
• Compatibility with POE, mineral oil, and fluorescent dyes

Which refrigeration systems and refrigerants are compatible?

The injector is built to work with a wide range of systems—automotive and HVAC—using common refrigerants. It supports R134A, R22, R12 and many R410A setups; for some 5/16" R410A ports you may need the CV23p adapter to ensure a proper fit.

• Designed for R134A automobiles and residential HVAC units
• Works with R22 and R12 service ports where applicable
• Adapter recommended for specific 5/16" R410A fittings
• Sealing components sized for standard low-side ports

What are the key build features and durability notes?

SURIEEN combines an aluminum alloy body with brass connectors and a reinforced high-pressure hose to handle field conditions. The kit’s check valve and screw-tight inner core help maintain a reliable seal and controlled discharge, while the metal construction resists wear from repeated service use.

• Aluminum alloy main body for strength and light weight
• Brass connectors for corrosion resistance and sealing
• High-pressure hose with 1/4" female fitting
• Check valve and screw mechanism for controlled release

How easy is it to install and operate for non-professionals?

The injector is engineered for straightforward, tool-free operation: screw the check valve on the cartridge, tighten the cylinders, purge a small amount of air, then attach to the low-side port. Clear step-by-step handling reduces guesswork so homeowners and fleet techs can safely add dye or oil when needed.

• Hand-turn design — no special tools required
• Simple purge step to remove air before injection
• Push-in action meters fluid; one-shot dosing possible
• Includes common fittings for quick setup

Who is this for? The SURIEEN AC Dye Injector Kit is aimed at HVAC technicians, automotive mechanics, and informed DIYers who need an efficient way to introduce lubricant or fluorescent dye into refrigeration systems without running the compressor. It’s useful for routine maintenance, leak tracing, and restoring oil level after repairs. If you work regularly on R134A-equipped vehicles, residential air conditioners, or service a variety of refrigerant systems, this compact, rugged injector is a practical addition to your toolkit. The product also ships with a one-year warranty and SURIEEN customer support for replacements or refunds if you run into issues.
