PTFE Lined Blind Flange
PTFE lined blind flanges are dual-purpose isolation components designed to either block or allow flow in corrosive piping systems. Featuring a solid steel body with an inert PTFE lining, they provide excellent chemical resistance and leak-proof sealing. The rotating design enables quick line isolation for maintenance or inspection, making them ideal for chemical, pharmaceutical, and process industry applications.
Key Features:
- Dual isolation design
- High chemical resistance
- Leak-proof PTFE lining
- Easy line switching
