Product details
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.

Sizing questions
How do I pick the right cap?
Measure the outside diameter (OD) of the flange. The cap inside diameter (ID) should match it.
Why are there two caps for one size?
Flange outside diameters vary with the pressure class, so some sizes come with more than one cap ID. Measure the OD and pick the ID that matches.
ANSI or DIN — which is my flange?
ANSI / ASME flanges are sized in inches (for example 4") with a pressure class such as 150 or 300. DIN / EN flanges are sized in DN (for example DN 100) with a PN rating. The standard and size are normally stamped on the flange rim.
