These ceramic eyelets can be polished to a smooth finish and are made in a variety of shapes and structures such as-
Tube Ceramic Eyelets for insulating instrumentation passage such as for thermocouples, cablings etc.
Slotted Ceramic Eyelets for neck sealing with purpose cut slot to accommodate design specific requirements such as for key grooved spaces.
Plain Ceramic Eyelets for neck sealing, soft passage, and rigid support such as for tubing and wiring passages etc.
Grooved Ceramic Eyelets for neck sealing, soft passage, and rigid support with the groove on the outer surface to add additional sealing via O-rings or ceramic seal rings.
Double Flanged Ceramic Eyelets with sealing groove on the outer periphery to allow additional sealing using O-rings etc.
Advantages
1. Alumina ceramic thread guide is highly wear-resistant and provide excellent durability in applications.
2. It is resistant to extreme temperatures, making it ideal for applications where high temperatures are a factor.
3. Lightweight and non-corrosive, it is an ideal choice for use in many different industrial applications.
4. Provide superior electrical insulation properties, suitable for use in electrical equipment.
5. It is also highly resistant to shock and vibration, making it an ideal choice for use in various industrial applications.
