Technical Information
DeWAL DW204-5HD is a Class 4 heavy-density skived PTFE tape meeting A-A-59474 Type I Class 4, providing the highest density and tensile strength in the standard A-A-59474 PTFE tape range. Class 4 designation indicates a heavier-gauge, denser tape than Class 2 variants, offering superior pressure resistance and longer-lasting thread seals under demanding high-pressure, high-temperature, and aggressive chemical service conditions. The 1.00″ width is suited for 3/4″ to 1″ nominal pipe size thread sealing in chemical processing, high-pressure gas distribution, cryogenic fluid handling, and industrial process piping where standard-weight PTFE tapes are insufficient.
Why Choose DeWAL DW204-5HD?
- 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 for demanding industrial pipe systems
- Skived Dense Construction — Superior thread sealing under high pressure and temperature extremes
- Universal Chemical Resistance — PTFE resists virtually all industrial chemicals and corrosives
- 1.00″ x 36 Yard Roll — Standard 1″ width for 3/4″ to 1″ NPS pipe thread applications
Frequently Asked Questions
Q: What is DeWAL DW204-5HD Class 4 PTFE tape used for?
A: DeWAL DW204-5HD is used for sealing pipe threads and fittings in high-pressure gas systems, chemical processing piping, cryogenic fluid handling, and demanding industrial applications where Class 4 heavy-density skived PTFE tape is required.
Q: What is the MPN for DeWAL DW204-5HD 1.00″ x 36 Yard?
A: The Manufacturer Part Number (MPN) is DW204-5HD-1X36YDS.
Q: What is the difference between DW204-3HD (Class 2) and DW204-5HD (Class 4)?
A: Both are A-A-59474 Type I skived PTFE tapes. DW204-5HD Class 4 is heavier and denser than DW204-3HD Class 2, providing higher tensile strength and better pressure resistance for more demanding service conditions.
Q: What specification does DW204-5HD meet?
A: DeWAL DW204-5HD meets commercial item description A-A-59474 Type I Class 4 for heavy-density skived PTFE tape for pipe thread sealing in industrial and military fluid systems.
Q: Is DW204-5HD Class 4 PTFE tape suitable for oxygen systems?
A: PTFE is chemically compatible with oxygen, but oxygen-service tape must also meet cleanliness and assembly requirements. Consult DeWAL and the applicable oxygen system specification before use in oxygen service piping.
