As long as it isn't plastic, the plastic has crystallized, and the pump breaks when you're using many kilometers/miles from home. that happened to me with my SILCA IMPERO. The pump broke in three places. I think there might have been hairline cracks in it that I never noticed.
My favourite pumps are the Zefal HP and the Zefal HPX. I need to try and find new heads for mine.
