Guangzhou Huite Sealing Machinery Co., Ltd.
PTFE Filler Spiral Wound Gasket China Factory and Leading Suppliers
Premium PTFE filler spiral wound gaskets from a leading China factory. Specialized suppliers for corrosive fluids, oxygen, vacuum sealing, LNG, and LPG applications across industrial pipelines and pressure vessels.
The Spiral Wound Gasket with PTFE filler is a high-performance sealing solution engineered for the most demanding industrial environments. Combining the structural strength of a metal winding with the exceptional chemical inertness of Polytetrafluoroethylene (PTFE), this gasket ensures a leak-proof seal in applications where corrosive media and high-pressure fluctuations are prevalent.
Specifically designed for the rubber and plastic components manufacturing sector and heavy industrial piping, these gaskets offer superior resilience and recovery properties. Whether used in chemical processing, pharmaceuticals, or petrochemical plants, the PTFE filler provides an unmatched barrier against aggressive chemicals, ensuring operational safety and reducing unplanned downtime.

Frequently Asked Questions
Q: What makes PTFE fillers superior for rubber and plastic industry gaskets?
PTFE fillers are superior due to their extreme chemical resistance and low friction coefficient, which prevents sticking and ensures a tight seal even when exposed to aggressive solvents used in rubber manufacturing.
Q: Can Spiral Wound Gaskets with PTFE handle high-pressure systems?
Yes, the spiral-wound metal structure provides the necessary radial strength to withstand high internal pressures, while the PTFE filler ensures a gas-tight and liquid-tight seal.
Q: How do I choose between SS304 and SS316L for the winding material?
SS304 is suitable for general corrosive environments, while SS316L contains molybdenum, providing superior resistance to chlorides and marine environments, making it ideal for petrochemical use.
Q: Are these gaskets compliant with international sealing standards?
Absolutely. Our gaskets are manufactured according to ASME B16.20 and other global standards (DIN/JIS) to ensure seamless integration into existing piping systems.
Q: What is the temperature limit for PTFE filler gaskets?
Typically, PTFE fillers can operate effectively from -200°C up to +260°C, depending on the pressure and the specific grade of PTFE used.
Q: Do you provide custom dimensions for specialized rubber part manufacturing?
Yes, we offer fully customizable dimensions and material combinations to meet the specific technical requirements of your industrial application.
