Built for the sea. YARRRRRRR!

The Sea Dog Freshwater Fill is a pretty simple component, but there’s more to it than meets the eye. Sea Dog designed its Freshwater Fill to be used on the decks of ocean-going vessels, so it’s built to withstand tons of abuse. That’s a good thing, because the exterior of your RV also deals with endless exposure to harsh weather conditions.

Sea Dog tough

To make the Freshwater Fill impervious to the elements, Sea Dog built it with heavy-duty, corrosion-resistant, investment-cast 316 stainless steel, which will be around long after the rest of your RV has rotted into the ground. The Freshwater Fill comes with an attachment chain to prevent you from driving off without the cap. They can’t make you remember to out the cap back on, but they can make it impossible to leave the cap behind.

Keeping your freshwater fresh

So, Sea Dog built the Freshwater Fill invulnerable to Mother Nature and owner dementia, but what about jackasses? The last thing you need is some turd stopping by your RV late at night to take a whiz into your freshwater tank. The good folks at Sea Dog are obviously familiar with jackasses. They designed the Freshwater Fill with a locking cap to prevent sabotage, contamination, and general jackassery to keep your RV and your family safe, even when you’re parked in a red state.

There’s a bunch of technical measurement type of crap that we should probably talk about, but we’re too lazy to bother with that. We’ll include it all in the bullet points below.

Features:

  • Slotted cap which requires a key to open & close for extra security
  • 1-1/2” hose deck fill cap diameter
  • 1-7/8″ thread pitch
  • 11-1/2 NPSM straight
  • Includes attachment chain
  • Constructed of corrosion-resistant, investment-cast 316 stainless steel
  • Installs with three #10 FH fasteners (not included)
  • USCG regulations require bonding wire to prevent sparking
  • Gasket sold separately (Sea Dog part #351349)
