This is my Pushrod Seal Kit that I have been selling for a couple of years. I feel they are superior to any other seal available. These seals are impervious to all lubricants and fuel that I have tested on them. They are very flexible and are 1.417 long and .610 at the largest diameter and will fit from a 2-56 size to 5/32 diameter push rod. The seal comes from Germany and the mount (I make from Garolite) is 11/16 diameter where it glues to the radio box, with an i.d. of 5/16.
They come in sets of 3 seals,3 mounts,and 3 o-rings.
