PTFE gaskets reinforced with metal mesh combine the chemical resistance of PTFE with the mechanical strength of stainless steel, delivering reliable sealing performance in harsh and hygienic environments. Widely used in chemical, pharmaceutical, food, and beverage industries, these gaskets are ideal for high-pressure, corrosive, and sanitary applications.
Metal Mesh Core: 304 or 316L stainless steel (or custom alloys) embedded in PTFE provides exceptional mechanical strength and dimensional stability.
Creep Resistance: Prevents leakage caused by bolt relaxation or PTFE cold flow.
High Pressure Capability: Superior to pure PTFE gaskets, allowing multi-fold pressure handling.
Full PTFE Encapsulation: Metal mesh fully encased in PTFE, ensuring only PTFE contacts the medium.
Resistencia química: Withstands strong acids, bases, organic solvents, and harsh chemicals, providing full protection for chemical processes.
Temperature Range: -200°C to +260°C, with short-term peaks up to +300°C.
Chemical Compatibility: Suitable for almost all corrosive chemicals and extreme environments.
Zero Contamination: Smooth, dense surface prevents adhesion, meets sanitary standards (FDA, EU 1935/2004 optional).
Safe Installation: Low friction prevents twisting or damage; no fiber shedding, maintaining fluid purity.
Sealing for flanges on reactors, heat exchangers, pumps, and valves handling chlor-alkali, acids, and hydrocarbons.
Sanitary pipelines, fermenters, and clean utility systems such as WFI water distribution.
CIP/SIP systems, pumps, homogenizers, and piping connections requiring sanitary seals.
High-purity acid, etchant, and specialty gas transport pipelines.
FGD (flue gas desulfurization) units and highly corrosive wastewater treatment equipment.
Any applications needing reliable sealing to prevent leakage of hazardous or valuable media.
Advanced manufacturing ensures tight bonding between PTFE and metal mesh, eliminating delamination risk and providing uniform sealing force.
PTFE Types: Standard, modified, or filled PTFE (glass fiber, graphite, etc.) for enhanced performance.
Metal Mesh: 304/316L stainless steel standard; custom alloys (Hastelloy, Monel) available.
Sizes & Shapes: Standard (ASME, DIN, JIS, GB) or non-standard dimensions, including complex geometries.
Low bolt stress requirements achieve superior initial and long-term sealing, reducing overall flange connection costs.
High resistance to aging and fatigue, extending maintenance intervals, minimizing unplanned downtime, and improving operational efficiency.
