Rubber conical washer

[searay495]

Hey folks, does anyone know where to purchase the white rubber conical washers that sit inside the threaded end connector that connects to the water pressure pump?
Thanks in advance,
Mark

They're called cone washers

Edit:
Yours may be 15mm

So I replaced the washer and the line continues to drip! It’s the line that comes out of the freshwater pump. Seems to be leaking from the backside of the threaded piece. Where it’s swivels on the pressure flange. But how can that be if the washer is meant from keeping the water from getting to that point? Also, when I unscrew the hose from that side of the pump, it takes forever for the pressure to empty that line! Yes, the pump is turned off!! Lol!

I think those fittings always end up cracking. That's why I touch them as little as possible. You may have to curt and replace that fitting with something comparable.

Lot's of threads/posts around these insidious fittings.

I just had to replace another one upon my spring commissioning. They leak when i look at them cross.
If it is, just be careful to NOT cut off any amount of hose that you don't have to.

Edit:
it isn't that they crack, it's that the hose that has the metal ring swaged onto the end has somehow lost its' compression. At least, that is what I have found.

Great info!! Will follow that thread for advice. Thanks!

They are an o-ring based seal, with a slip on stainless "bight" ring to retain the tube as mentioned. The o-rings tend to dry out with age and they crack and leak. The outer PVC rings rarely crack unless someone tries to over tighten them to stop a leak. The rings should only be hand tight. if they leak its the o-ring or tubing and no amount of tightening will help. I replaced every o-ring in my '94 and did not have a single fitting crack. And have no leaks now.
