M8 laser ceramic insulator , 20mm top diameter , high temperature resistant ceramic body with brass thread , O-ring included , for fiber laser cutting head replacement.

Material Introduction The main insulator body is made of high-purity white alumina ceramic, featuring excellent high-temperature resistance, stable insulation performance and low thermal deformation. The threaded connecting part is precision machined brass, which delivers good wear resistance and smooth thread fit. A durable rubber O-ring is pre-assembled for reliable sealing and dust prevention during laser cutting operations. Instructions Inspect the ceramic body for cracks
