I read the part number as

X6L114-X400-N/N

It's obviously a "special" since K&L usually uses letters like B for 
bandpass filters and L for low pass, but the X means something. Assuming 
this is a low pass..


The N/N is the connectors

the 6 is the number of sections
L is the "low pass"
the 114 is the size, but 114 is not a standard tubular filter size (110 
is, and is comparable to what you've got.. more than an inch in 
diameter, and 200W power handling)

the 400 is the cutoff (400 MHz)

But I'd send them an email.. they'll look it up and tell you
