Exactly what I wanted!
3 years ago
Fitted to sailing canoe I just completed, built from a CLC kit. Otherwise auto bilge pump discharge would have had to go over deck. This way plumbing's all inside save for the tapered bronze escutcheon this fixture incorporated on the port top strake. Very elegant, very purposeful!

High Quality - Competative Price

The internal ""wrench tabs"" are not as large as competitors, and should be increased in size during the casting process.

Good quality fittings

These are well made thru hull fittings. They thread easily into Groco and other brands of seacocks. It makes for a good installation.

Q: null Is the inner diameter of the 3/4__quote__ thru-hull less than or equal to 11/16ths? I am looking to add threads all the way through the interior of one of these brass thru-hulls. Specifically, I want to take a thru-hull with 3/'4__quote__ NPS threads on the exterior (I'm looking at the TH-750-W), and add 1/2__quote__ NPS threads to the interior. Is there enough material to do this? I believe the hole needs to be a clean, reamed diameter of 11/16ths (and not a 64th smaller) to accommodate being tapped with 1/2__quote__ NPS female threads. Thanks! Justin Roettger
