Replaced the galley and front head faucets but water keeps leaking at the black plastic fittings, there are yellow rubber washers in them, I’ve tried but can’t find replacement washers.
Anyone have a source for washers or better way to replace the fittings with newer shark bite that slip on waterline and attach the 5/8” nuts that go to faucet?

can you maybe try regular hose fitting washers, they are 5/8" fittings
 
It's safe bet that McMaster-Carr has exactly what you need.
A quick look finds these guys, although I have no clue if that is what you're after.

Polyurethane Rubber Washers
 
Hey Jeff, I wonder if you could try an off-the-shelf o-ring? I chased issues with those fittings for a few years on my previous 500DB. Ended up being the crimped on section that contains the threaded fitting. It was a real pita because Sea Ray saved money by providing zero slack in those hoses. They were cut and fitted at the factory with zero tolerance and in some cases, so tight I could barely get them back together.
 
I'm sure there are other sources.

Pex fittings, they sell them at Lowes and Home depot. Take the seal ring off the new one or replace the whole thing

I will agree with @tc410 as to the failure of the crimp connections. Many members here have chased a lot of different leaks that always seem to end up being the crimp connections and some have gone so far as to replacing almost every one on their boat. @bbwhitejr and maybe @ttmott also. That being said, I would lean towards @ocgrant s suggestion, these

The conical shaped washers can be had at freshwater systems.com I believe. I started with that fix only to find compression clamps were where the leak was. I used pex fittings. The problem comes in that the barb portion of the fitting is a quite a bit smaller than the ID of the hose. Just slapping a hose clamp on will not get tight enough because the hose is so thick. Get the hose clamp started and then heat the hose with a heat gun. Once the hose is hot, then crank down on the clamp. The other fix was to buy compression clamps and tool from McMaster Carr.

As mentioned above, the is very little slack in the hoses. Be careful and remove no more than you have to.

I probably replaced 50-60 on our 44DB.

That's the post/thread/website I was thinking about.
Good job Sir. Hope all is well.
 
Here is the original thread:

Leaking Water Connections

Anyone have any experience with SeaTech Marine Uniflex hoses and fittings? I have some that are dripping at times at the 1/2” hose connection. There is nothing wrong with the hose, but the connections drip. I can buy the hoses with the hose connections attached, but they are not cheap and I...

In the 44DB, these drips/leaks will lead to water in the stringers as well. Fortunately there is no wood in them so it does no real damage other than to weigh the boat down. In another thread, I cut a 6" hole in the center stringer in the ER and installed an inspection plate. First time I vacuumed out maybe 6-7 gallons of water. As I got around to repairing the leaks, water was less and less until it all went away. Funny thing was, sold the '07 DB and moved to an older '03 420DA and never had the first leak from the identical hoses and fittings....
