Starter leak-detection kit
OPK-541 Industrial Leak Detection Kit is a new starter kit designed to effectively pinpoint the exact source of all leaks in hydraulic equipment, compressors, engines, gearboxes, fuel and other synthetic and petroleum-based fluid systems. It comes with the Optimax Jr blue light LED flashlight, a compact, high-intensity unit that quickly reveals all leaks in small to medium-sized industrial systems — even in cramped areas that are inaccessible to larger lamps. It measures just 7¼ inches (19 cm) long and weighs only 5 oz (140 g).
