I am wondering where you guys have found these grommets/glands/adapters for your charger projects. I need one for my battery pack.

They're not used on the Tesla Model S or Model X so I think you'll have to find a breaker who has the relevant car (or 3D print some?).

They also appear to use them on junction boxes.

Are these the parts you're looking for?

Where did you find this? What part does this go to?

This is the waterproof crimp that plugs into the Front HVJB. The other end of this cable is terminated in a non-waterproof crimp (see photo) that plugs into the Rear HVJB.

I've purchased most of my HV cables at very low cost or even free with other Tesla parts. In most cases I figure the cost of the Tesla cable is less than I'd pay for the crimps and the crimper.

One important point to remember is these are screened cables... that's why they have two connections, the round ferrel connects to chassis ground and the spade connects to HV.

I think I found the fittings. They are the lower fittings in the photo for this ebay auction. The one with a single silver ring around it.

So that's the cable from the Model X or possibly a facelift Model S. The difference is the HV modules on the latest cars are 'waterproof' unlike the charger/HVJB on the original Model S.
