For 25 + years my firm has been suggesting adding a shaft anode in front of a PSS shaft gland to help with the known issue of collar creep. It is nice to see PSS has this product the seal retention collar to tackle this issue. We suggest it or the humble anode be part of your installation. Now if only they would include a date system so that the installation date could be easily identified and retrieved for bellows replacement, like on a battery.
