Product details
Polyethylene flange cover cap for DN 40 DIN flanges, sized to protect the 150.5mm gasket face from dirt, moisture and impact.
This push-fit cap seals over the raised face of a DIN DN 40 flange, creating a protective barrier during storage and in-transit. The polyethylene construction resists moisture and mild chemicals, making it suitable for on-site and temporary applications across maintenance work and pipeline 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.
