What kind of fitting/cap is this?

[tbrady]

Trying to figure out what type of cap this is that goes on the hot/cold water drain.  It's a 1/2" threaded cap with a gasket in it...  I haven't been able to find anything like it though...

I could really use an extra one to cap off a new drain I added to the freshwater tank.

thanks again

looks like a standard pvc cap with an o-ring like those used with garden hoses.  if you cant find an exact replacement, look in the pvc area of lowes/home depot for a 1/2" or 3/4" pvc cap (cant tell the right size from the picture...take one of yours in to measure) and then get the o-rings from the gardening area

I tried that already and it doesn't seal anything like the black cap.  I bought a pvc cap and added an appropriate sized o-ring but it still drips pretty good.  The black cap has some sort of convex shaped gasket in it and seals really good...  The gasket doesn't really fit inside the standard 1/2" pvc cap though.
