18mm dia. ring, 4ft metal shield wire.
Similar to Falcon Gauge
Made in China
They were delivered on time and fit perfectly for my application
I purchased 2 senders for my dual temp Gage, both failed with in minutes of each other? the problem was one of the wires broke on each, I had to remove the ring then re solder the wire and reinstall the ring. both sensors work fine and seem to display the correct temp. these sensors are fragile and must not vibrate.
Yes, it is type J. Lead is 4 feet.
