16" ANSI Flange Cover Cap - 647.7mm ID, Polyethylene

Polyethylene flange cover cap for 16" ANSI flanges, protecting gasket faces and sealing surfaces from dirt, moisture and impact.

This rigid polyethylene cap slides over the raised face of a 16" ANSI flange to seal the bore and shield the sealing surface during storage, handling and on-site assembly. Designed for Pressure Series 300 applications, it provides a secure temporary barrier that prevents costly rework and maintains flange integrity through the supply chain and field operations.
