Seal tape (JIS compliant products)

  • Life-related products
  • RoHS Directive


This is an unsintered PTFE tape that is used for sealing of various kinds of piping screws. As it is soft and self-adhesive, sealing work can be easily done. As it does not deteriorate in quality for a long period of time, removing work is also easy.

Main applications

• Water pipe, oil hydraulic equipment pipe, chemical device pipe
• Insulation coating material
• Others

Operating temperature limit

-100℃ to +260℃

The Chuko Flow (R) sealing tape is certificated as Japanese

Industrial Standards JIS product. (JIS K 6885 2 types)


• Since the tape is soft and self bonding, the sealing operation of the piping screw is easily performed.
• Since the tape does not deteriorate over long periods, the work of removing pipes is also easily operated.
• The tape has chemical resistance and hence can withstand most chemicals, solvents and gases. (Except the molten alkali metal.)
• Excellent flame resistance and electric insulation.
• Very thin type with 0.04mm thickness is also available. Please contact us directly.
