Technical Information
DeWAL DW204-8HD is a Class 4 (heavy density) skived PTFE tape meeting A-A-59474 Type I Class 4 specification, providing the highest density and tensile strength in the A-A-59474 skived PTFE tape range. The Class 4 designation indicates a heavier-gauge, denser tape than the Class 2 (DW204-3HD), providing superior pressure resistance and a longer-lasting thread seal under high-pressure and high-temperature service conditions. It is used in demanding chemical processing, high-pressure gas systems, cryogenic fluid handling, and industrial piping applications where standard or medium-weight PTFE tapes are insufficient for the application pressures and service conditions.
Why Choose DeWAL DW204-8HD?
- Class 4 Heavy Density — Highest density in A-A-59474 range for maximum pressure resistance
- A-A-59474 Type I Class 4 Spec — Specification-grade heavy PTFE tape for demanding industrial systems
- Skived Construction — Denser, more uniform, and stronger than extruded PTFE tape
- High-Pressure Rated — Provides reliable thread seals in high-pressure gas and liquid systems
- 1.00″ x 36 Yard Roll — Standard 1″ width for larger pipe thread and fitting applications
Frequently Asked Questions
Q: What is DeWAL DW204-8HD Class 4 PTFE tape used for?
A: DeWAL DW204-8HD is used for sealing pipe threads and fittings in high-pressure gas systems, chemical processing piping, cryogenic fluid handling, and industrial applications where heavy-density Class 4 skived PTFE tape is required for superior pressure resistance and seal longevity.
Q: What is the MPN for DeWAL DW204-8HD 1.00″ x 36 Yard?
A: The Manufacturer Part Number (MPN) is 204-8HD-3-4.
Q: What is the difference between DW204-3HD (Class 2) and DW204-8HD (Class 4)?
A: Both are A-A-59474 Type I skived PTFE tapes. Class 4 (DW204-8HD) is a heavier, denser tape providing higher tensile strength and greater pressure resistance than Class 2 (DW204-3HD). Choose Class 4 for high-pressure or demanding service conditions where Class 2 is insufficient.
Q: What specification does DeWAL DW204-8HD meet?
A: DeWAL DW204-8HD meets commercial item description A-A-59474 Type I Class 4 for heavy-density skived unsintered PTFE tape used in pipe thread sealing and industrial fluid handling applications.
Q: Is DW204-8HD Class 4 PTFE tape suitable for cryogenic applications?
A: PTFE remains flexible and chemically stable at cryogenic temperatures, making it suitable for cryogenic pipe thread sealing. Verify specific cryogenic suitability with DeWAL and the applicable system specification before use.
