Introducing Poly-U™: A New Standard in PTFE & PFAS-Free Thread Sealing

As industries move toward safer, more environmentally responsible materials, the demand for high-performance sealing solutions without fluoropolymers or PFAS continues to grow. That’s why we developed Poly-U™, an innovative polyurethane-based thread seal tape engineered to deliver reliable performance—without PTFE and without PFAS.

Poly-U provides the sealing strength and durability professionals expect, while supporting evolving regulatory and environmental goals. With Poly-U™, you can move forward confidently, knowing you’re choosing a solution that combines proven performance with a more sustainable future.

While Poly-U is an excellent PFAS-free choice for a wide range of applications, our LOX-8 line remains the preferred solution for extremely harsh chemicals and the most demanding service conditions—ensuring you always have the right product for every environment.
