Product Description

Product Description

Introducing the Spring Energized PTFE Seal, a marvel of engineering designed for superior performance. This spring-energized, pressure-assisted sealing device is crafted with precision, featuring a PTFE (or other high-grade polymer) seal that partially encapsulates a meticulously engineered, corrosion-resistant metal spring energizer, ensuring unmatched reliability.

Our PTFE jackets are precisely machined to perfection, filled with advanced PTFE composites and other high-performance polymers. They are designed to function seamlessly across a wide temperature range, from cryogenic conditions up to 250°C. These jackets are incredibly inert, resisting almost all chemicals, and some variants are also suitable for sanitary environments.

Material
Our seals use PTFE that is meticulously filled with materials like bronze, glass, graphite, carbon, and more, ensuring optimal performance for your specific needs.
