PTFE Tape for Making Spiral Wound Gasket
Model:GR102
PTFE Tape For Making Spiral Wound Gasket is made from 100% PTFE with a special process molding. Expanded PTFE tape for making spiral wound gasket can conform to any surface, including rough, pitted, scratched and damaged surfaces. We can supply the common PTFE tape and expanded PTFE tape.
A spiral wound gasket relies on a precise combination of metal winding and soft filler material. The GR102 PTFE Tape serves as the soft sealing filler layer wound between the metal strips to create the sealing element. The density and cross-section of the GR102 PTFE Tape are engineered to match standard spiral wound gasket dimensions — 5.7–6.0 mm width for 4.5 mm SWG and 3.9–4.3 mm width for 3.2 mm SWG.
Two versions of the GR102 PTFE Tape are available. Common PTFE tape has a density of 2.25 g/cm³ and provides maximum chemical resistance in standard applications. Expanded PTFE tape has a density of 0.8 g/cm³ and conforms to rough, pitted, scratched, and damaged surfaces for superior sealing in demanding flange conditions.
With excellent insulation, acid resistance, and corrosion resistance, the GR102 PTFE Tape delivers a strong tight seal for threaded joints, oxygen systems, portable water systems, and pipe linking systems in buildings. Request a quote →
Two PTFE Tape Versions. One Purpose.
Direct answer: The GR102 PTFE Tape is available in two density versions — common PTFE (2.25 g/cm³) for maximum chemical resistance, and expanded PTFE (0.8 g/cm³) for conformability on irregular flange surfaces.
GR102 PTFE tape ready to be wound as the soft filler layer of a spiral wound gasket.
GR102 PTFE tape combined with V-shape stainless steel strip to form a complete spiral wound gasket.
Technical Specifications
Direct answer: The GR102 PTFE Tape operates from -240°C to +260°C, handles up to 100 bar, and resists chemicals from pH 0 to 14. Two density options: 2.25 g/cm³ for common PTFE and 0.8 g/cm³ for expanded PTFE.
Other widths of the GR102 PTFE Tape are available on request. Custom cross-sections and spool lengths can be produced to match your winding machine requirements.
