Goop The Thru-Hull

With the seacock installed and bedded lather up the thru-hull fitting. The beveled mushroom head of the fitting is what creates the water tight seal and is the most important place to put sealant. Putting some on the threads is only a secondary measure and adds some thread lubrication when tightening it down.

other sizes: small medium large
