Hi - they are made by a company called Voss, in Germany. It's their 'Quick Connect' system - I think the 246 series. However, I don't think they sell to the public.

Hello, my bad I should have given this info earlier,
yes, VOSS246 oem for Tesla, only selling Corporate

but located these via Aliexpress,
first batch had VOSS label (???), second batch were blanks

https://www.aliexpress.com/snapshot...orderId=100595095323853&productId=32852791474

There's another company Aowei Trading
with NW-7
https://nl.aliexpress.com/item/NW-1...ive-connector-for-water-hose/32809798728.html

I had both brands ordered, and they will fit the coolant line connector 6.4Kwh module
just an extra info Tesla is not using the white retainer clip in their production??

best and thanks for helping

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?

I'm not explaining myself very well, but I was going to do something like this:


https://www.facebook.com/zeroevuk/photos/a.222383741661135/562554984310674/?type=3


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).


Hopefully useful for someone.

Nice!
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.
See attached photo's.

Very nice - that Laser tool looks useful. I'm going to see how I get on with some shaped silicon tubing. If I can find the right shape, it shouldn't be OK. I hope!
