Sizing questions
Which disc size do I need?
Pick the disc for your flange standard and nominal size. The disc diameter is in the title so you can check it against the flange face.
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.
Does it come off before assembly?
Yes — peel the disc off before the gasket goes in.
