53mm GID O-Ring's?

[SmurfTacular]

I have searched high and low for GID O-Rings that would fit in a Maglite, between the lens and the reflector. But I have been unsuccessful in my search. I have found that Sigman sells them here at CPFM, but the biggest size he has is 25mm.

Anyone know anywhere that sells 53mm GID O-Rings? Thanks.
