Allied Electronics www.alliedelec.com and Newark Electronics www.newark.com between the two of them you should be able to find Abbatron, Neutrik, Switchcraft, etc. insulated RCA's, insulated phono etc. place "insulated washer" in their search engines.
a good trick i used is to buy some teflon / ptfe plumbers tape and wrap the treads with it ( you will need to wrap it round several times) - this of course has added benefits that it will work as a lubricant on the thread making it easier to get a good tight lock.
also teflon/ptfe is a very good electrical insulator..

Hi,
Not such a great tip IMO.
Plumbers PTFE tape is rather thin and flexible:
Wrap it around the threads a few times, put the locking screw on and if the jack is of any decent quality you'll have screwed the nut straight through the tape already.
Even if it still insulates the jack from the chassis at that point, by the time you've inserted and disconnected your cable a few times the mere applied force will have eaten straight through the PTFE insulation.
The wisest thing to do is exactly as Bill Fitzpatrick suggested:
Get some proper shouldered insulation washers. They were made for the job and will save you a lot of headaches looking for groundloops.
Oh, they don't really need to be made out of PTFE either...much better in all respects but DA are the ones made out of polycarbonate; they'll stay put unlike that slippery PTFE stuff.
Cheers,
