Product details
Polyethylene flange cover cap engineered to seal and protect ANSI-standard pipe flanges from dirt, moisture and mechanical damage.
This push-fit cap slides over the raised face of a 2½" ANSI flange to shield the gasket seating surface during warehousing, transport and installation. Moulded from durable polyethylene, it resists chemical attack and impacts whilst remaining lightweight and easy to handle on site.

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.
