Fresh Water Drain valve threaded cap

[kbltmlaur]

I'm looking for somewhere I can buy a replacement for the threaded cap that holds the drain valve onto my 1/2" fresh water line, near the water pump. The thread cap is cracked. I'd like to just replace that cap, but if needed, would replace the entire drain valve. For my 1996 Winnebago Adventurer.

Thank you.

You could probably match that compression ring up with another component at one of the big box hardware stores, but the cost is likely the same as the replacement of the valve at RV store… I bought that same valve for about $12 at my local RV store.
