Silicone D20 O-ring for ZnSe lenses

Description

Description

Silicone D20 O-ring for ZnSe lenses designed for sealing and thermal insulation of lenses and mirrors in laser cutting and engraving machines. The ring is compatible for use with 20 mm lenses and mirrors in most common models of CO2 laser machines and engravers.

When the machine is operating, the laser head and the mirror are heated. The use of silicone rings isolates the working surfaces of lenses and mirrors from temperature effects and prevents their premature damage, increasing service life.

The silicone ring has an outer diameter of 20 mm, an inner diameter of 16 mm and a thickness of 1.5 mm. The appearance may be different from what is indicated in the image.
