O' rings for HWH 325 leveling solenoids
I am replacing the o ring seals on a HWH series 325 solenoid. ( Part no. RAP90729) New seals were purchased from HWH. (Part no. R7430) There are 48 seals in the HWH box. 28 that have a square cross section (16 with ID 9/16 in., 8 with ID 11/16., and 4 with ID 3/4 in.) 20 that have a circular cross section (8 with ID 9/16 in., 8 with ID 11/16 in., and 4 with ID 3/4 in.)
It appears that the old o rings were not HWH originals and instructions on were each type new seal is to be installed were not included. I am waiting for a call from HWH, expect it will be several weeks.
Will greatly appreciate instructions on which seals go on the valve end and on the end that exits the manifold.
