Product Description

Product Overview
Introducing the sophisticated Spring Energized PTFE Seal-a marvel of engineering designed for the most demanding applications. This seal is a seamless blend of a spring-energized, pressure-assisted design, featuring a PTFE (or alternative high-grade polymer) component that partially encloses a corrosion-resistant metal spring energizer, ensuring unmatched reliability and performance.
Crafted with precision, the PTFE jackets are infused with superior PTFE composites and advanced polymers. These jackets boast exceptional thermal resilience, operating efficiently from cryogenic lows to a scorching 250°C. Their chemical inertness makes them ideal for diverse applications, including use in stringent sanitary environments.
