Silicone Push Button Replacement

[sk1020owner]

Hello, I have a 2006 Komatsu SK1020. The pilot control levers have several 12mm size push buttons to operate accessories and other functions on the machine. The silicone button covers are deteriorated and need to be replaced. I can't find them anywhere without having to purchase the entire valve/lever/control assembly. Anyone know where to get just the silicone cap/covers for something like this?

Have you tried the dealer to see what they want for them? they may not be stupidly expensive...
