Need help identifing the connector on Smartpool Nitro cord, any electrical geeks?

Try Lashen Electronics' web site. It's www_dot_lashenelectronics_dot_com. They MAY have what you need. It looks a lot like a microphone barrel connector and since these cleaners are low voltage, that may do the job.

blueenergy how many terminals is used in the connector. i only see 3 being used in the first picture.. if it is only using 3, Pos, Neg, ground try your local radio shack.. they carry alot of amature radio connectors. you can waterproof many of them yourself.
