How do you measure a thru hull fitting?
thru hulls and other fittings are measured according to “nominal pipe size”. this is more or less an inside diameter of the fitting. I.e. the hole in your thru-hull will be about 1/2″ in diameter if it is labeled as a ‘1/2″ thruhull’.
How tight should a thru hull fitting be?
With the seacock tightened snugly — not too tight — you should have plenty of threads inside the seacock, but the length of the through-hull should not prevent the base of the seacock from tightening against the plywood ring.
How does a through hull work?
A thru Hull fitting requires a hole to be cut/drilled in the boats Hull for the fitting to pass through. Thru hulls can be used to expel waste water, such as from a sink, to let sea water in, such as for engine cooling or to allow placement of sensors such as depth gauges.
How do I get rid of my hull?
Removal of the old thru-hull is easy:
- First remove any hose clamps attached to the hose.
- Next remove the hose from the valve.
- Using pipe wrenches remove the valve from the thru-hull.
- Using pipe wrenches or in some locations a chisel remove the locking nut from the thru-hull.
How do you drill through fiberglass without cracking it?
First use a smaller drill bit to make a hole. Then use a bigger than needed drill bit to just drill through the gelcoat, (not the fiberglass) this will allow you to use the final drill bit, to drill through without causing the gelcoat to crack.

When should I replace my through hull fitting?
If the metal is pink, the thru hull fitting should be replaced immediately, since the metal has no strength and is ready to fail. One easy way to do this is to spray a PTFE type lubricant up into the thru hull when the ball valve is open and also spray the handle area the day before (this can be done in the water).
Where do most boats sink?
dock
About two out of every three (69 percent) boats sink at the dock or mooring, while the remainder (31 percent) sink while underway. Of all of the dock/mooring sinkings, 39 percent occur when some small part gives up the fight with water due to wear, tear and corrosion.
Are through-hull transducers better?
