the packing nipple too hard!

The gland gland kit includes all

Simrad recommends that a one inch conduit (that the
hydrophone cable will be run through) with an inside threaded
diameter of three-quarter inches be attached to the gland’s
packing nipple. This connection must be watertight, and the
conduit must extend to over the vessel’s water line and
terminated as described for steel hulled vess els.
