NEXCUT PTFE Laser Seal Ring for Fiber Laser Cutting Head

NEXCUT laser seal rings are designed for sealing applications inside fiber laser cutting heads, helping maintain stable gas pressure and protect critical internal components from gas leakage, dust and contaminants.

Manufactured from high-performance PTFE combined with a stainless-steel spring structure, the seal provides low friction, good wear resistance and reliable sealing performance under repeated movement and pressure conditions.

A wide range of sizes is available for different protective lens assemblies and laser cutting head configurations.

Key Features

High-performance PTFE sealing material
Stainless-steel spring energized structure
Low friction and good wear resistance
Stable sealing performance under pressure
Good chemical and temperature resistance
Helps reduce gas leakage inside the cutting head
Suitable for protective lens and cutting head sealing positions
Multiple dimensions and customized specifications available
Compatible with different fiber laser cutting head configurations

Function

The seal ring is installed around the protective lens holder or other sealing positions inside the laser cutting head.

Its main function is to maintain a reliable seal between mating components, reduce cutting gas leakage and help prevent dust and contaminants from entering sensitive optical areas.

The internal spring provides continuous sealing force, while the PTFE sealing surface helps maintain low friction and stable performance during long-term operation.
