Hinged Shower Screen Seal

[Hondacr84]

Evening. I purchased a house 1.5yrs ago and the hinged shower screen has started to leak. I’ve tried several new seals and none seem to work. As you see by the photos the original is a double seal and the end by the hinge is solid plastic piece which has a screw in. I’m not seeing any branding on the screen apart from on the glass. Just wondering if anyone has seen this seal anywhere? Thanks
