@neauoire Forespar (Marelon) or TruDesign are great and more importantly, UV stable - steer clear of the cheap unbranded tat in chandleries :)

TruDesign or Groco are the only brands of sea cock / through hull I'll allow anywhere near my boat.

Just an FYI - when double-clamping a hose with jubilee clamps, you want to have the clamps on opposite sides like in the original rusty pic - the area under the body of the clamp is where you may get leakage so offsetting them cures this 👍
