PFA
PFA offers exceptional chemical resistance, flexibility, and clarity, making it perfect for Ultra-High Purity Fittings used in semiconductor wet benches, chemical delivery systems, and wafer cleaning equipment.
DEK produces PFA tubing and fittings with smooth internal surfaces that prevent particle buildup and ensure consistent fluid flow. Its thermal stability and cleanliness make PFA ideal for maintaining purity in high-temperature and corrosive fluid-handling applications.
PTFE
PTFE is a chemically inert, non-reactive fluoropolymer ideal for Ultra-High Purity Fittings in chemical distribution lines, gas handling systems, and medical fluid transfer.
DEK manufactures PTFE fittings with ultra-smooth, non-stick surfaces that prevent contamination and ensure high chemical compatibility. Its superior heat resistance and dielectric properties make it the preferred choice for environments demanding the highest purity and long-term reliability in corrosive or high-temperature operations.
PVDF
PVDF is a tough, chemically resistant fluoroplastic widely used for Ultra-High Purity Fittings in high-purity water distribution, chemical processing, and microelectronics systems.
DEK fabricates PVDF fittings that maintain strength, cleanliness, and dimensional stability over long operational cycles. Its resistance to acids, bases, and solvents ensures dependable performance and purity, making PVDF a reliable solution for demanding fluid-handling applications across critical industries.
Instant & Accurate Quotes
We don't use online automated quotation tools, because it is very inaccurate. Online quote platforms rely solely on calculations based on cutting amounts and fixed coefficients, they fail to account for actual processing nuances, such as material deformation after heat treatment, tight tolerance requirements, grinding after heat treatment, etc. Consequently, automated price calculations can lead to inaccuracies, ultimately increasing your costs.
But you can rest assured at DEK!
Our quotations are both cost-effective and accurate because we have a team of professional mechanical engineers who meticulously review each drawing. These engineers boast over 10 years of experience and possess deep expertise in programming, machine operation, post-processing, material properties, and more.
