Mark,
Our field service engineer told me (rather unapologetically) the new guard
cartridges are of smaller O.D. His suggestion was that this could be fixed
if you replaced the end seals in the Brownlee holder. So far, I tried one
and it leaked so I'm using up the rest of my stock of old cartridges before
disassembling the holder. Best of luck.
