Hi - yes, you are right - the OEM ones from VOSS come with the white plastic clip, but Tesla don't use them.
I am planning to use these manifolds from Zero-EV, but I will also need to join the centre ports of the 6.4KWh modules. I was going to use the VOSS connectors and standard 8mm hose, unless you can recommend anything else you have found to join the ports up?
And then it will be basically the same as the 5.3KWh version. I am planning one manifold for input coolant on one side, then to join the two coolant inner ports, then another manifold for coolant exit.
One manifold inlet, one manifold outlet. And then connect the inner ports together on the 6.4KWh.
I saw those corrugated nylon tubes on Aliexpress and they are similar to what Tesla use. But I thought the material was very stiff and not really possible to insert the Voss connectors without a special tool?
The material is PA12, I have not worked with it before so I don't know if you can heat it to make it easier to insert the connector?
Here is a picture of one of the Tesla joiners that connect the inner two ports on the 6.4KWh modules.
The connectors are 90deg VOSS units - like the Aliexpress ones in above posts (I think). The corrugated nylon hose I think is 6mm, and it's formed into that shape somehow. The pipe at the back is for main coolant flow and I think is 12mm. Again, nylon, and really hard/stiff.
The joins all look like push-fit, but needing a tool. I'm 90% sure I won't be re-using this piece, I've got some VOSS connectors and I'm going to try to find some kind of moulded hose to replace the corrugated hosing. Using normal coolant hosing takes up a lot of space.
Below is also a view of the coolant in/outlets for 6.4KWh module, and how Tesla did it (alas, my pipes were cut before I got them, and I don't have a complete set either).
Good to hear there is a mating connector by the way.
You need tooling indeed. I bought a Laser tool but a sealer gun, clamp and some creativity will get you there.
Without heat works best in my view after doing some test.
Make sure you use the nylon tube only for connectors with a rubber seal.
