REPLACING MARBLE AIRLOCK ON MARCHISIO 500L TANK

vouxwines · Aug 13, 2022

I’d like to replace the factory marble airlock on my Marchisio 500L tanks with a standard S-shaped water airlock. Last season I used a #10 bung with the s-shaped airlock but the steel lip of the lid hole dug into the rubber and some debris could get into the wine. Just was not an elegant solution. I can’t seem to find anything that would screw on with gaskets providing a reliable seal with the ability to push on an s-shaped airlock. Anyone else have a solution they can share? Would also like to outfit my Spiedel tanks with the same solution.

Have you seen the tank toppr airlock risers?

TankToppr™ Airlock Riser

The exclusive TankToppr&trade Airlock Riser is the best way to prevent leaking and excessive headspace in your variable capacity tank.

I haven't used them, but am in the samw boat as you looking for a better solution than the marble ones. They take a silicon bung in the top which could be vented for a s-lock.

This is your solution for the Speidel fermentors: Grommeted Airlock Cap for Speidel Plastic Fermenters | MoreWine

On the marble lock, instead of rubber have you considered silicone? It's more flexible and you won't get the debris you cited. Something like this: https://www.amazon.com/HNGSON-Taper...fix=silicone+stopper+with+hole,aps,129&sr=8-6

Thanks everyone! I went with the riser and a #9 stopper for the Marchisio and for the Spiedel tanks I went with the grommeted adapters from Northern Brewers. They are great!
