Leak Saver UV Dye Inject | 3 Pack Dye Only for Automotive, HVAC, and Refrigeration (Up to 5 Tons) – Made in USA

Find Leaks Quickly and Easily

The Leak Saver UV Dye Inject system delivers a clean, dye-only solution designed for automotive, HVAC, central air conditioning, and refrigeration applications up to 5 tons. Inject the dye using a basic manifold gauge or our dedicated Leak Shot Injectors, run the system at maximum cooling for 30–60 minutes, then illuminate with a UV flashlight to locate the leak site. The glowing dye offers fast visual confirmation, with occasional visibility to the naked eye in well-lit conditions.

This 3-pack focuses on simplicity and clarity: there are no syringes, hoses, or pressurized cans to manage during installation. You’ll inject dye directly into the system, observe under UV light, and identify the source of leaks with minimal mess. Made in the USA, the dye is formulated to work across a broad range of refrigerants and oils, making it a versatile option for various service scenarios.

Why this dye stands out

• Mess-free setup: dye-only solution eliminates the need for syringes or sealants, simplifying diagnostics.
• Wide compatibility: suitable for most refrigerants and oils, and works with central A/C, cars, mini-splits, heat pumps, and more (ammonia excluded).
• Clear, visible results: the dye illuminates at the leak site under UV light and can be seen with the naked eye in bright conditions.
• Easy installation: pair with a standard manifold gauge set or our Leak Shot kits for straightforward injection across common systems.
• Dye-only formulation: no sealant mixed in; check our other products for sealant options if needed.

How to use in the real world

Whether you’re working in a busy auto shop, a home garage, a marine maintenance yard, or a commercial refrigeration room, the dye provides a practical way to spot leaks without guesswork. After injection, operate the system to simulate normal cooling conditions, then scan joints, coils, valves, and connectors with a UV flashlight. The result is a practical, actionable view of where refrigerant is escaping, enabling targeted repairs rather than broad, trial-and-error replacement.

What you can expect in practice

• Automotive applications: insert dye via standard 134A connections and inspect condensers, evaporators, and hoses for bright, fast glow at leak points.
• Residential and commercial HVAC: apply to central systems, ducted networks, and shared coils to reveal hidden leaks.
• Marine and refrigeration: monitor boat AC lines and cold-storage coils for precise leak localization.
• Maintenance and troubleshooting: use the dye as a diagnostic aid during routine service or before sealant application if needed.
