So in a 2010 thread GuzziSteve mentioned a seal kit from Hermy's in PA. So I called and got Hermy Jr because Sr is in Italy. tough gig. Anyways, they transferred me to Kathy and she was quite helpful. They have a set of NOS paioli struts for my bike but I think I would run into the same issue as I am having now, bad seals? They want 170 not including shipping from PA which isn't bad just not an expense I was expecting right now. All I really need to know is where to find the piston cup seal at the metering end and the double lip seal at the cap. The oring is an MS28775-019. The dimensions for the piston cup seal are ID 12mm by OD 24mm and 7mm thick. The original cap seal was from a company called Corteco but they claim to not make that seal nor do they know of an equal (PN 12010240B). I have a few leads on something close out of Poland but I haven't heard back yet. Also since we are nearing Thanksgiving getting anything out of Poland is a long shot until after the new year between snow and holidays. All the hardware looks good otherwise I would be closer to grabbing the NOS. I know there are replacements but I if I can I would really like to keep it somewhat original. The left side still holds air but I am still using the crossover tube so it leaks out the rh side.
So, Opinions? Kathy told me also that the Part number Steve gave me from Paioli for the rebuild kit is a good number but doesn't know if they have any or can get them. Internet turns up nothing on that kit number also. So let me know what you think!
And a great big hearty thanks to GuzziSteve for the lead!

yessir, been through all those. The Polskis say they got something close but not exact and the 12010240B is no longer made according to Corteco. So i did the next best thing. I removed the spring in the seal, u screwed the ends from each other, clipped ~1/16” from the non tapered end and screwed them back together. No leaks. Oiled and Serviced. on to the next project.... Leaky rear main seal....

Hi.
I rebuilt a set of Paiolis many years ago and couldn't find the correct seal for the cap. The ID and OD combination just wasn't something that was available locally so I bored the cap to take a seal with a larger (by 2mm as I recall) OD. The guide bush that sits in the top of the damper tube and the bottom of the cap was then sleeved to match the larger bore in the cap. You could do it the other way around depending on what seals you have available. I used standard oil seals which lasted very well but a proper shock absorber seal would be better.
Worked for me for as long as I used those shocks.
