O ring size on valve train oil pipes size?

There are several o-rings on the three oil transfer pipes in the top end near the chain. The next valve adjustment I’m replacing all the rubber parts. Partzilla has them at nearly 3.59 each! I could buy Viton for half that. Anyone know what the actual size is? I’ll buy them at McMaster for 15% of that!
 
Ive never replaced those and never heard anybody else replace them. But the size is 13mm O.D x 2mm cross section. The one I just measured has about 50k miles on it and actually measured 12.75mm. so thats about .005" per side deformation.
