Fluorescent Dye for Industrial Leak Detection

Using fluorescent dyes and ultraviolet technology for leak detection is a simple and smart investment.
As well as finding leaks our fluorescent dyes work as a preventive maintenance to your system and will reveal leaks in the future.

Using the appropriate leak detection tools will help preserve equipment quality and extend service life. Undetected leaks can lead to equipment breakdown, lost production time, safety issues and even fines and legal penalties. When it comes to cost savings, ease of use and effectiveness fluorescent dye for industrial leak detection is the ideal way to find costly leaks in Industrial systems!

Spectroline® dyes work effectively in any closed-loop circulatory systems where fluids are used for lubrication, hydraulics, cooling control or hydrostatic pressure testing. Spectroline® dyes can remain safely within the system and are NSF certified to meet non-contact food-grade requirements. Ideal for use as part of a diagnostic & preventative maintenance program to keep systems operating efficiently.

Whether it’s oil, water or hydraulic fluid system, leaks impact both the environment and your bottom line. Spectroline® offers a wide range of products designed to pinpoint the exact source of every leak, including OEM-grade fluorescent dyes, high performance leak detection lamps, kits and specialty products.

Finding Leaks at the Speed of Light

Fluorescent leak detection made simple.

Whether it’s oil, water or hydraulic fluid, leaks impact both the environment and your bottom line.

Undetected leaks can lead to equipment breakdown, lost production time, safety issues, and even fines and legal penalties. That’s why it is so important to find and implement a safe, efficient and cost-effective leak detection program. Here are some testimonials from industry professionals relating how Spectroline® products quickly and easily resolved their leak detection issues.

“In my industry, we need black lights to check for hydraulic oil, engine oil and antifreeze leaks. The OPTI-LUX™ 365 exceeds our expectations. It is compact, lightweight, cool to the touch and provides a good viewing beam up to 5 or 6 feet (1.5 L- 1.82 meters). Looking forward to the next generation of UV LED inspection lamps from Spectroline®”.

Joseph J Palmiotto

“As a manufacturer of hydraulic cylinders, the integrity of our welding process is critical. We test 100% of our products and have found that it is much easier to identify leaks that may exist in welded joints by using Spectroline OIL-GLO® dyes and inspection lamps. We have been using these products for years and have been very happy with their performance.”
