Buna o-rings # 208-90d
Exact replacement for my Sears 3 ton floor jack. I’m sure to find other applications as well.

ordered wrong size
They look like good quality, I watched a youtube to repair a craftsman 3 ton floor jack but mine was 2 ton. I was hoping it was rather universal, I was wrong. The correct size I believe is buna 90 #113 for my sears craftsman 875.50128 2 ton jack piston oring. Searsparts direct lists my jack as 87550128. I wasted 6 bucks on these with shipping. My local Fastenal was pushing me to buy an assorted box for $40 w.o tax. I will gladly go this route any day and recommend this sites oring sizing chart. Cant thank this store enough for saving me over a hundred bucks for a new floor jack. Now I have to figure out which way the springs and ball bearing go! Off to youtube!
