I've been nursing along my dried, cracked and brittle Silver King AD main gasket for some time but wonder if anyone has ideas about replacement. This creates the seal between the two main halves of the unit, around the edge of a basketwork disc that also serves to seat the main filter. Photos should clarify the problem. Hard to find gasket material anything like this. A T-shape with a slit to allow it to grab the circumference of the disc. I can't be the only one with this woeful situation!
Thanks in advance.
