Tracer Products: The Originators of Fluorescent Leak Detection

Since 1955, Tracer Products has been setting the standard for automotive leak detection. Headquartered in Melville, New York, this privately held company is widely credited as the originator of fluorescent leak detection technology — a method now trusted by OEM manufacturers, professional technicians, and fleet operators around the world. Decades of innovation have made the Tracerline® brand synonymous with accuracy, reliability, and environmental responsibility in the service bay.

What sets Tracer Products apart is a genuine commitment that goes beyond simply finding leaks. Refrigerant leaks, oil leaks, and coolant leaks are not just efficiency problems — they are environmental hazards. By enabling technicians to find and fix even the smallest leaks quickly, Tracer Products helps reduce refrigerant emissions that damage the ozone layer and minimizes fluid contamination that harms ecosystems. Their products are engineered with that larger mission in mind.

A Complete System for Finding Every Leak

Tracer Products offers a fully integrated approach to leak diagnosis. The process typically starts with a A/C system dye injector — Tracer's EZ-Ject™ and BigEZ™ injector lines make it fast and clean to introduce fluorescent dye into any A/C system, including modern R-1234yf vehicles. Once the dye has circulated, technicians reach for a UV leak detection flashlight — such as Tracer's OPTI-PRO™ cordless violet LED flashlight — to scan the system and make leaks glow brightly, even pinpointing hairline cracks invisible to the naked eye.

The fluorescent A/C system dye at the heart of this process is formulated to circulate safely without altering lubricant properties or affecting system performance. Tracer's TRACER® UV dyes cover all major refrigerant types — R-134a, R-1234yf, and beyond — as well as engine oil, hydraulic fluid, coolant, and transmission fluid, making a single product line applicable across virtually every vehicle system.

For shops that need a broader diagnostic toolkit, Tracer Products' lineup of A/C repair tools includes couplers, purge fittings, and complete service kits designed to streamline refrigerant work from start to finish. And for leak-checking without dye injection, their A/C refrigerant leak detectors provide electronic sensing technology to catch escaping refrigerant gases before a problem becomes a costly repair.

OEM Trust, Professional Performance

Tracer Products' OEM-grade quality is not just a marketing claim — major vehicle manufacturers have chosen Tracerline® dyes as factory-fill solutions, validating the brand's formulations at the highest level of the industry. Whether you're a dealership technician working on the latest EVs, a fleet manager keeping heavy-duty trucks on the road, or an independent shop building a reliable diagnostic workflow, Tracer Products delivers the tools and chemistry to get the job done right the first time.
