This is Stephen Allen also known as ACR junior Guru. Does anyone Know the McMaster-carr part num for seals to rebuild the salon slide rams on coach 502 ?

I did not know how to paste a link to my post about my slide cylinder woes on coach 500, but here is what was in there.  I can only imagine you have the same cylinders

Slide cylinders is HWH AP15845 but same as HWH AP21812
The O'ring store UL125-0.875-125 High Performance Loaded U-Cup
The O'ring store AN-07-SH 7/8" Rod Wiper Seal (This was the lowest price for MS28776-7 I could find by far)
The O'ring store AS568-916 Buna-N 70 Duro (I used a 3mm x 30mm seal sized off less than 2% since I did not know there were special oring sizes for "bosses")
