  • Which shaft seal to use for a dry hull sub


    I realize that the Merriman/Caswell seal for rotary motion is the DES00(3 or 4) but I'm wondering if the push rod seal, DES00(1 or 2), would also work if the only rotary motion was that of a servo shaft, i.e., slow rotary motion and not constant. I'm thinking of using them for dive planes and rudders on a dry hull sub.

    Both types would serve well in that capacity.
