Product details
Polyethylene flange cover cap for DN 250 DIN flanges, designed to shield exposed gasket faces from dirt, moisture and impact damage.
This cap fits over the raised face of a DN 250 DIN flange to form a protective seal during storage, transit and on-site handling. The polyethylene construction resists moisture and many chemicals, and the snug internal fit prevents the cap from dislodging. It is a temporary protective measure that keeps the gasket sealing surface clean and undamaged until final assembly.

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.
