Study of various fittings used on bulk chemical supply system

When selecting a fluoropolymer fitting design to be used in ultra high-purity chemical applications, decision makers must consider different performance characteristics. A recent study was conducted that measured key fitting attributes, such as fitting pull-out force, cleanliness and assembly time. The study compared commercially available nonwetted insert, flare, and wetted insert style fittings. The methodologies employed and the test results are detailed in this paper.
