Hercules Bulldog is the Mfg. I pick them up at the hydraulic shop that rebuilds my cylinders. They make standard , metric , Japanese Etc. They have a huge master catalog they ship out for free.

The most common O-rings are the buna the black ones. Two durometers 70 for most mobile applications 90 for static applications (boss type fittings ) . Viton would be the brown ones high heat and special apps but they're a PITA they cut / nick real easy.

Everything seems to be throwaway nowadays these kits have saved me more than once.
