Product Information

With almost 50 years of experience in PTFE machining processes, at Merefsa, we specialize in the manufacture of high-precision technical parts. Our catalog includes PTFE bellows for the fine chemical industry, expansion joints, O-rings, gaskets for glass installations in fine chemicals, shaft linings, valves, balls, segments, standard gaskets, custom parts, die-cut gaskets, and other products.

Thanks to our production flexibility, we can manufacture anything from single units to large series, offering customization in colors and adapting to the drawings or samples provided by our customers. We have machining capabilities of up to 750 mm in diameter, which, combined with our high specialization and quality standards, positions us as one of the most versatile and specialized companies in the manufacture of PTFE bellows and technical parts.

Machined PTFE is primarily used in sealing and leak-proof applications in highly corrosive environments, thanks to its exceptional resistance to most industrial chemicals. Its wide thermal working range, from -200 °C to +273 °C, makes it ideal for extreme temperature conditions as well as for use in sliding or non-stick applications in sticky or welding processes, due to its low coefficient of friction.

Our deep knowledge and experience in the manufacture of sealing gaskets and PTFE parts allow us to offer specialized technical advice in the design and development of new parts, providing innovative solutions for various industrial applications. At Merefsa, we have a state-of-the-art machinery park, which includes CNC lathes, manual lathes, CNC and manual milling machines, ensuring maximum precision and efficiency in each of our manufacturing processes.
