Product Description

Product Description

PTFE Gasket

High-Temperature PTFE Gasket is a premium sealing solution designed for superior insulation and durability in extreme environments. Crafted from high-purity PTFE, it excels in applications demanding reliable performance under harsh conditions.

With a temperature range of -200°C to 260°C, it maintains structural integrity in both cryogenic systems and high-heat industrial furnaces. Its exceptional insulation properties make it ideal for electrical enclosures and power equipment, preventing electrical conduction while reducing heat transfer.

Resistant to strong acids, alkalis, and organic solvents, it ensures leak-free sealing in chemical processing, pharmaceutical, and food industries. The low-friction surface minimizes wear, enhancing longevity even with frequent use or exposure to detergents.

Available in custom sizes and shapes, it fits diverse flange types and equipment specs—from oil and gas pipelines to power plant valves. Its durability reduces replacement frequency, cutting maintenance costs.

This gasket combines high-temperature tolerance, insulation, chemical resistance, and long life, making it a trusted choice for critical sealing needs in tough industrial settings.
