Water Tank Gaskets


 

Any recommendations for gaskets for the water and holding tanks? They are a gooey mess.
?
Apologies if this is an old topic.

Thank you,

I bought replacement O-rings for the cleanout ports on the water and holding tanks from Grainger, as well as deck fills. The minimum quantities were high (10 and 25) for the different sizes, but they were not expensive.

I never thought of Grainger...Or McMaster-Carr.

Or your local marine chandlery if they carry engine parts; so $12 cash for three sets of four ring gaskets (water, waste, diesel) is better than $16 for one at WM. Just bring in the old ones to match. Grainger is great idea.

The extras are on the boat and I don¡¯t recall the sizes. I used a caliper to measure them, and then found something close at Grainger.?

I was able to find the water will and waste pump out o-rings at my local hardware store. ?I don't remember the sizes but I have the spares on my boat. ?I have yet to find replacements for my water and holding tanks, thanks for the suggestions.

I have about a dozen go-to suppliers mostly from suggestions on this forum. For me, Grainger's niche is fairly routine items, but items where I need to match sizes, threads, materials, etc.. I have a few locations between me and the boat where I can pick up orders. Their website is very detailed on specs, and it shows availability, usually same day or next morning pick-up.
