Hi Skipp

The common white Teflon coax that I run across is RG-188. You are correct I
have never seen the part number on it but Teflon jackets do not take
printing well.

A fairly complete listing of Teflon coax cables is below

RG Number       Belden Number   Cable OD        
RG-393                          .390            50 Ohm, RG-8 size coax
RG-304/U                        .280            50 ohm
RG-141A/U       83241           .187            Single shield, 50 Ohm
RG-58 size coax
RG-142B/U       83242           .195            Double shielded,50 Ohm RG-58
size coax
RG-400/U                        .195            50 Ohm RG-58 size coax
RG-303/U        84303           .170            50 ohm
RG-180/U        83264           .141            50 ohm
RG-187A/U       83267           .111            50 ohm, White Teflon tape
jacket
RG-188A 83269           .108            50 ohm, White Teflon tape jacket
RG-179/U        83264           .100            75 ohm RG-174 size coax.
Very common for 75 ohm cabling
RG-316/U        84303,84316     .098            50 ohm,
RG-178B/U       83265           .071            50 ohm, Very small Teflon
coax

Thermax/sonic (http://www.thermaxcdt.com)  is another large manufacturer of
Teflon coax cables.

RF parts has RG-316, 141, 142, 179

Also of interest for those making some types of power splitters and
combiners for solid state power amps
Communications Concepts (http://www.communications-concepts.com) 
has 25 ohm coax DA25070, DA25090, Microdot D260-41180-0000.

Hopefully this will give you some options to chose from.
