38 x 30 x 4mm Laser Sealing Ring — Ospri 608 & 808 Fit
Protective window sealing ring for Ospri 608 and 808 fibre laser cutting heads.
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.
