Replacement cup seal for rainmaker?

[Jordan]

Sounds about right.

I managed to reduce the leak by pinching an o-ring between the cupseal and valve stem and replacing 1 valve body o-ring. I only had 1 replacement valve oring, i have more coming in the mail eventually. Dumb question but what size is the valve body o-ring? I measured a -018 but im not 100% sure.

Yea ill try replacing the valve orings again before trying anything else. Thank you for the offer i appreciate it.

If either of the two orings around the valve body are nicked they can leak down the barrel - make sure they're also in good shape.

If you need a new valve due to damage, I think I have a couple kicking around still.

I figured i had nothing to lose and cut the old cupseal off . It was threaded with loctite. i tapped the azodin cupseal and put it in. The seal is better but i still have a small leak. Im guessing that the valve's surface is nicked and either needs to be refaced or sanded down.

[Jordan]

Yes, they're different.

Got a picture of the cupseal?

I think my rm is the early model. Are the valve stem assemblies different between the two models or is it just that the early ones have loctie holding them together?

[Jordan]

They should - I think the later RM cupseals are serviceable like that.

Sorry for all the questions. I've managed to get the Rainmaker to catch and cycle. Im getting a leak down the barrel and it looks like the cup seal face is scratched and should get replaced. Are there any cupseal assemblies that are available currently that could replace it?
I have azodin and spyder cupseals that are the same diameter and slightly longer in length. Would those work if i managed to remove the stem and thread the new cupseal on? Thank you for your time.
