VescoaT supplies PTFE Lined piping for the chemical, pharmaceutical and associated industries. The PTFE fluoropolymers are chemically inert having near universal corrosion resistance which we specifically use to convey the most corrosive and toxic processes in Chemical and Pharmaceutical plants around the world. It is also used in high purity applications and an alternative to exotic materials such as Hastelloy. VescoaT is the stock and manufacturing distributor on PTFE lined piping products. VescoaT also manufactures and supplies PFA / FEP / HDPE lined fittings by using most advance and innovative techniqes.
VescoaT has been designing, processing and manufacturing the highest quality paste extruded PTFE and PFA lined products for 10 years. Our products are acknowledged to international standard of ASTM F1545, We pride ourselves in offering high levels of customer service and high integrity products.
