I think I'm going to purchase a set of these for the front and rear brakes. I think it will complement my stainless steel lines that are going to be installed this spring. What size do I need to purchase? I found a thread on another sportbike forum and the poster said that the SB8125L model had exposed threads. The Speed Bleeder site says to purchase this model. There is a regular SB8125 model that's a little shorter.

Which one do I need to purchase?

Have you tried contacting them to get an answer on this? What did you eventually do? I'm thinking of getting these.
