|---|---|
| Main Body | SUS304 PFA (Perfluoroalkoxy Alkane) Coating |
| Rubber Packing | Fluoro-rubber |
Application
FPD production equipment / Semiconductor fabrication wet processes /Printed circuit board etching devices / Metallic surface treatment
equipment and facilities / Cleaning equipment / Chemical plants
Characteristics
- Sealing washers with a built-in rubber seal.
- Sealing washers prevent the leakage of gas and liquid from the bearing surface of the screw head.
- The washer body is coated with PFA (Perfluoroalkoxy Alkane). The rubber seal is made of fluororubber, which has excellent chemical resistance.
- Chemical Resistance of P Coating⇒Chemical Resistance of Chemical Resistance Screws
Usage Example
Use with SNHS-HTF Hex Head Screws-PFA Coating for Head(SNHS-HTF) to prevent chemical liquids from moving from the bearing surface to the thread.
- Airtight test at 0.6 MPa confirmed that there is no leakage.
Precautions for Use
- Friction with the screw bearing surface during tightening may remove the coating. Take care not to tighten too much.
- When combining with SNHS-HTF, use the recommendation torque of SNHS-HTF or less for tightening.
