Tuga, how and where does the Newell attach the air supply line?

But now I understand they do not make a loop but in fact have and open ended loop so I presume the ends meet beneath the slide. So this begs the question as to why a Prevost seal cannot be applied in the same fashion. I guarantee I could find a rubber extruded that will sell the material direct. Especially if it works and if the issue of attaching the supply line can be resolved. I tend to agree about the corners based on what I have seen of the slide seals I have been involved with.
