PCTFE Machined Parts

PCTFE machined parts are designed for precision assemblies that require chemical resistance, mechanical strength, and long-term stability. Each part is manufactured with tight tolerances to ensure reliable sealing, insulation, or support in demanding environments such as semiconductor tools, cryogenic systems, and analytical instruments.

The material, polychlorotrifluoroethylene, contributes to this performance with its excellent dimensional stability, very low gas permeability, and resistance to acids, bases, and oxidants. It maintains rigidity from cryogenic to elevated temperatures, ensuring that components retain their shape and function over time.

ESI produces a range of PCTFE components, including spacers for mechanical alignment and insulation, sealing rings for leak-free interfaces, and other custom parts such as bushings, washers, fittings, fasteners, etc. These parts help maintain clean, contamination-free operation across high-purity industrial systems.
