Product Details

Groco Bronze Thru-Hull Fittings are threaded with combination NPT/NPS thread, where the first inch is tapered (NPT), and the remainder straight thread (NPS). Use with Groco Seacocks, as these are the best choice for below-the-waterline use. They are supplied complete with a bronze locknut or they may be threaded directly into a compatible seacock.

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.
