Good product- well made & cost effective

Product was used to add a drain to a humidifier holding tank so that the tank could be drained for easier removal. Drain was connected through a shut off valve to an existing 5/8 inch vinyl tube. Had to buy a neoprene washer to make it leak tight. Two humidifiers were modified and the total cost of the parts was less than $15 for each tank.

Q: My bulkhead is 2-1/4__quote__ thick. Will this thru hull work? My hose is 3/4__quote__ dia.
8 years ago3 Answers
A: I ordered these previously and they were to short. T-H Marine part# TH-750XL worked on my 2 1/4__quote__ hull with 3/4__quote__ hose. They are on the flimsy side, don't over tighten and use plenty of sealer you should be fine. Mine have been in for over a year now,no problems.
