In ultra-pure and corrosive fluid-handling environments, the smallest variation at a tubing connection can become a leak path, a contamination risk, or a repeatability problem. That is why tubing end formation matters as much as tubing material selection. When fluoropolymer tubing (commonly PFA or FEP) is used with flare-style fittings, hot flaring mandrels help produce a consistent flare geometry that supports reliable sealing and predictable assembly results. Below is how hot flaring mandrels support quality, what “good” looks like in practice, and how teams can reduce variability when flaring tubing in the field or on the production floor.   What [...]

In demanding industrial environments (where chemical attack, temperature extremes, contamination risk, and mechanical wear are everyday challenges) material selection is paramount. Fluoroplastics are increasingly the material of choice for industrial components because they combine exceptional chemical resistance, wide thermal tolerances, and long-term reliability with performance characteristics that outperform many metals and standard polymers. At Crist Group, we leverage a range of fluoroplastic materials and advanced fabrication capabilities to deliver industrial solutions that stand up to harsh conditions while maintaining integrity over long service lives. This post explores the key benefits fluoroplastics bring to industrial applications and how Crist Group’s [...]

Selecting the right fluoropolymer is fundamental in designing ultra-pure fluid systems where contamination, corrosion, and chemical interaction are non-negotiable concerns. Two fluoropolymers frequently considered in high-purity applications are PFA (perfluoroalkoxy alkane) and PTFE (polytetrafluoroethylene). Both materials offer exceptional chemical resistance and thermal performance, but their differences in fabrication, performance, and application can determine which is the best choice for your system. At Crist Group, we specialize in high-purity fluid process assemblies and fabricate systems using both PFA and PTFE among other fluoroplastics like PTFM (weldable PTFE), FEP, ECTFE, and PVDF. Our deep experience in application-specific material selection ensures you get [...]

In high-stakes industries like semiconductor manufacturing and life sciences, fluid systems must deliver purity, reliability, and consistency. At Crist Group we do more than deliver parts.
