Leak-Detecting Pipe Flange Covers with pH Patch
When a tiny amount of liquid makes contact with the pH patch, it changes color to indicate a leak. Patch is orange when neutral. The wrap-around design of these covers contains acid and caustic pipe leaks, protecting personnel and equipment.
PTFE-coated fiberglass covers are highly resistant to acids, alkalies, and most chemicals except hydrofluoric acid.
