Rich,

I'm not certain why, but the U-182/U and U-229/U are the worst of all of the 
O-ring sealed bayonet coupling connectors that I've encountered.  I suspect 
that if you could push hard enough, you would cave in the panel before you would 
get a dry O-ring in the cable connector to pop over the nose of the U-183/U 
chassis connector.

I tried ordinary silicone grease as well as an O-ring lubricant made by 
Parker.  Both worked fine.  I can't say which would last longer.  Saliva usually 
only works once.

If you are ever caught out somewhere trying to attach a handset or etc that 
has a dry O-ring, and no grease of any sort on hand, simply remove the O-ring 
from the cable connector.  Also, the proper way in which to lube the O-ring is 
to remove it from the connector so that you get grease on the OD as well as 
the ID.  And put a thin smear on the chassis connector as well.
