So I gotta HiSi my cat broke my slide and my downstems cracked at the bottom so I think it's time for a new bowl/Downstem, and I needa know what size it is, I'm pretty sure it's 14mm but I'm not sure, here's some pictures if you guys could help me out in figuring out what size it is,
Yup, for future reference downstems are measured by the male (external) size, so you can just grab a ruler to be sure.
