26.3 x 19.6 x 3mm Laser Sealing Ring — Precitec ProCutter & LightCutter Fit
Protective window sealing ring for Precitec ProCutter and LightCutter heads using the 21.5 x 2 window.
The sealing ring sits in the protective window drawer and seals tightly around the lower protective window. It keeps dust and dirty assist gas out of the cutting head cavity, protecting the focusing and collimating lenses from contamination and burn damage. Replace it whenever it's flattened, nicked or hardened, and ideally whenever you change windows.
