Got a cylinder with a 4.75 inch rod that needs a new wiper, this the right size to drop in?

Question by: Jerry M on Nov 29, 2025, 1:21 PM

For a 4.75 inch rod diameter, yes, this is the correct fit. The wiper OD measures 5.50 inches with a 3/8 inch base thickness, so those are the dimensions you'll want to confirm match your gland or housing before ordering. The part number is ST-475, also cross-references as C1DL52 if you're working off an old parts list.
