This professional rubber seal (O-ring/retaining ring), with precise dimensions of 29.8 x 24 x 3 mm, was designed specifically for WSX laser head optical systems (compatible with the 30-5 lens and cassette mounting system). This component is installed in the head socket, where it ensures cleanliness and maintains the correct auxiliary gas pressure inside the fiber laser housing.

Made of a specialized elastomer resistant to high temperatures and aging, the ring maintains optimal flexibility even during prolonged operation of a high-power laser. This prevents microscopic leaks that could lead to contamination of expensive optical components. Regular replacement of the seal during optical maintenance protects the head from premature wear. The product is fully compatible with popular WSX cutting head models (including selected versions of the KC15, NC30, etc.).
