GFT 9 PFA Transfer Molding Meets Precision Engineering

PFA Lined Sight Glass

Videron9
The GFT9 Videron PFA/Teflon double window sight glass is the ultimate solution for operators requiring continuous, real-time observation of process media in highly corrosive and high-pressure environments. Designed for both vertical and horizontal installations, it offers unmatched durability and reliability with minimal maintenance. Its virgin PFA lining provides superior chemical resistance against aggressive, reactive, and permeating substances, far outperforming stainless steel or standard plastic alternatives. Additionally, its vacuum-proof anchoring system, secured through mechanical clamping, ensures exceptional sealing integrity, preventing leakage and structural failure—even in extreme process conditions. With a robust, pressure-bearing metal body and double borosilicate glass windows, the Videron guarantees safe, clear, and obstruction-free monitoring of liquid levels, flow, and fluid conditions. Trusted across industries from chemical processing to pharmaceuticals, food & beverage, and petrochemicals, it sets the standard for reliable and maintenance-free sight glass solutions in the most demanding applications.
