Fishbox thru-hull on 20SF

[thehermit]

Greetings all,
I have replaced the thru hulls on both my fish box and the hull. Originally they were connected with a little 90 degree(ish) piece of black hose clamped to each of the thru hull fittings. At least I think this was original equipment. Anyways I need to find a suitable replacement to re-connect these two. Any suggestions? I remember Strick doing a loop around deal but his pics are down. I have already cut a larger pie plate in so it is fairly easy to get to now (well sort of).
Thanks
