With lots of cheap plastic on the market (selling for top dollar), JD came through by offering a quality material at an affordable price. I don't take chances with thru-hulls, and I use this one!

Weakest thru-hull fitting I've used. Tightened with channel-locks turned sideways in restricted space (not much torque possible) and I stripped threads on first of four fittings used. Will have to order another to match and will go easier on torque.
