anybody know what shape/type of window gasket this is?

[NHW]

Had a sample pack come in and neither of them seem to be the same/similar to my existing window gasket.

Not sure if it might be a specific type. but any help would be appreciated if someone just randomly happens to know. Thank you

Window seems to be an old aluminium double-glazed type (if thats any help)

Weird one for sure, its definately not a rubber gasket, looks like EPDM or neoprene, you may have to just use the closest wedge gasket you can find

Not seen a wedge gasket like this before but when I had a similar problem I sent a sample to a company called Extrudaseal and they identified their closest match for me.
