These stainless steel sapphire inserts stand out from the competition and outperform other materials such as ceramic or steel. This is thanks to a very compact and aggressive water jet. The integrated jet stabilizer ensures a concentrated and powerful water jet density. The service life of a sapphire insert is much longer than that of hardened steel nozzles or other drilled inserts. Sapphire inserts are used primarily in the clean-water jetting industry. Sapphire inserts are less suitable for dirty water (recycled water).
