The TCRS® Air Test Stand locates leaks in seconds by pressurizing the converter with air and immersing it in water. This process is capable of detecting minor imperfections including pinhole leaks. It works on all torque converter models from the Allison 1000 to a Volkswagen®/Audi® converter and virtually any size hub with the nine included rubber grommets. The air operated hand lever, regulators and seal make the TCRS® Air Test Stand extremely fast. It's designed for convenience with the ability to raise the water level to any height on the converter and also lock the converter at 45 or 90 degrees making leak repair or adding balance weights easy.
