[MurrayM]

Anybody have any experience with New Zealand's Trudesign composite thru hulls?

I like the design but I don't have any actual experience with them.
I think I'm going to stock them. Raritan is the US importer.

Looking at the spec sheet, they have special wrenches for these valves. My question is how do you get the wrench off the fitting once it is attached to the piping?

I wonder how they compare with Marelon valves? They seem similar.

Wow. Does that ever make sense! The Kiwi's are world leaders in innovative marine technology.

In principle I really like the concept of a plastic valve, just think not wanting them serviceable is stupid. My boat came with Marelon seacocks. The valve body easily disassembled with 4 screws. The valve could be rebuilt and lubricated by replacing 3 orings and lubing it. According to Marelon, that should never be done (too complicated). In the end, decided to replace them with traditional Groco seacocks properly fastened to the hull.
