UniShield Window Protection
Fused PFA Glass Shielding for Sight Flow Indicators & Sight Windows
Shielding Options Available
Jacoby-Tarbox’s full line of sight flow indicators and sight windows are now available with UniShield, a fused PFA glass shield. This latest innovation in glass protection from Jacoby-Tarbox is available for window discs and cylinders for both positive pressure and VACUUM service. This technology incorporates PFA fluoropolymer powder coating over a clear catalytic primer resulting in the fused PFA shield.
This technology is the latest addition to the standard loose PFA/FEP, PCTFE (formerly known as Kel-F®), and MICA shields currently employed by process engineers for hazardous service and glass protection.
