Sentinel Cup Seal

idkfa · 05-13-2008, 09:07 PM

I just bought an AM Sentinel, and I am trying to collect some parts "just in case" something goes wrong. I don't want to be stuck with a gun that does not work because AM no longer makes parts.

What parts generally cause potential problems, and are these proprietary or common parts? I am thinking namely of the cup seal.

Anyone?

a spyder cupseal ought to work like factory. most other parts can be found at the hardware store, or from a different manufacturer.

I had some and the valve itself was worn out. It was an aluminum valve. I am not sure if all sentinel valves are aluminum but they are a point of wear. I have a very early piranha and its valve is also aluminum, but they changed them to stainless quite early in production and I assume that wear is the reason.

So maybe look for extra valves as the sterling valve is unique.
