PTFE seals perform exceptionally well in high-temperature conditions, typically handling continuous service up to 260°C and intermittent spikes beyond. They maintain low friction, chemical resistance, and flexibility at elevated temperatures, but their mechanical strength can decrease, requiring careful design or filler reinforcement to prevent creep and ensure long-term reliability.

Spiral wound gaskets with inner and outer rings provide enhanced structural integrity, precise centering, blowout resistance, and controlled compression, making them ideal for high-pressure and high-temperature sealing applications.

Learn the essential steps for proper installation of expanded graphite gaskets to ensure a reliable, leak-free seal in flanged connections.

The ideal hardness for a ring joint gasket depends on the flange material and service conditions, typically ranging from a maximum of 120 HB for soft iron to 160 HB for low-carbon steel, with softer gasket materials generally preferred to prevent damage to flange faces during compression.

This article explores the reusability of double jacket gaskets after disassembly, examining the key factors that determine whether they can maintain a reliable seal or need replacement.

PTFE gaskets provide excellent chemical resistance, a broad temperature tolerance, low friction, and non-stick properties, ensuring reliable sealing in aggressive environments.
