Robinair 16356 is a four-pack of 1 oz. twist-on fluorescent dye cartridges designed to quickly locate refrigerant leaks in automotive and HVAC A/C systems.

These compact cartridges give technicians a reliable, OEM-approved method for finding leaks without altering system performance. Each 30 ml cartridge installs directly into compatible service kits and delivers bright, long-lasting fluorescence under UV light, helping you isolate leaks faster during diagnostics and repair. The set is SAE certified, fits Robinair kit numbers 16350, 16380, and 16355, and includes service stickers for service recordkeeping.

How does this dye help me diagnose A/C leaks?

The fluorescent dye disperses through the refrigerant circuit and accumulates where pressure or temperature changes allow refrigerant to escape, making even small leaks visible under UV inspection. It’s formulated to work with common automotive refrigerants and is accepted by vehicle manufacturers.

• Bright fluorescence for easier UV detection
• Small 1 oz. cartridges for controlled, measurable dosing
• Works with standard refrigerants used in auto A/C systems

How much coverage do four cartridges provide?

The pack contains four 30 ml (1 oz.) twist-on cartridges; together they supply enough dye for approximately twenty standard service applications when used at recommended dosages. That makes this set practical for small shops or mobile technicians who perform routine A/C diagnostics.

• Four cartridges × 30 ml each
• Estimated 20 typical applications per pack
• Twist-on design for quick cartridge changes and minimal waste

Will this dye fit my Robinair service equipment and meet industry standards?

Yes. The cartridges are specifically sized to attach to Robinair kit numbers 16350, 16380, and 16355 for seamless use. The formula is OEM-approved and SAE-certified, supporting compliance with service protocols and shop expectations.

• Compatible with multiple Robinair kit models
• OEM approval and SAE certification for professional acceptance
• Includes service stickers to track dye use and inspection dates

How do I apply the dye safely during service?

Install a single cartridge into the matching Robinair service kit following the kit instructions, then run the system to circulate dye. Inspect joints, hoses, condensers, evaporators, and fittings with a UV lamp to reveal leaks; always follow safety guidance for handling refrigerants and shop chemicals.

• Use with appropriate Robinair service kit and UV lamp
• Run system long enough for dye to circulate before inspecting
• Follow refrigerant handling and PPE recommendations

Who is this for? The Robinair 16356 four-pack is aimed at professional technicians, independent shops, and experienced DIYers who need a dependable, shop-ready dye solution for pinpointing leaks in automotive A/C systems. It’s particularly useful when quick diagnostics are needed across multiple vehicles or when keeping service records and following OEM-approved procedures is important.
