New Contitech airbags!! How to connect the 4mm air line.

[Bohica]

The new Contitech have a white plug where the air line goes in, easily removable, I am guessing that you do not undo the brass part, as the screw in part has a blob of green, to see if the screw in part has been removed. Push the airline in? I can't see that working. I do not want to try anything as I do not want to stuff it up.
What is the correct procedure?

Or go to ENZED and buy a screw in part with a 4mm push fit?

You have to unscrew the voss connector(which is a kind of compressin fitting) push the pipe through it then tighten it back just make sure that if you remove it to not drop the inner "olive" pointed with the red arrow in the pic which will retain the pipe when it gets tight if you see what i mean...if you pulled out the white bit that olive might be in the bag's thread, put it back where it belongs

[Bohica]

Thanks Sierfafery, the white bit stays there?

[sierrafery]

If you can push the pipe through it past the olive then yes, if not bin it and fit the olive on the SLS pipe.... i didnt use new voss connectors untill now but on the original bags the olive was directly on the pipe, maybe the white bit is just to not drop and lose the olive when you remove the connector... it's very like a compression fitting

[Bohica]

How much 4mm tube sticks out past the 'olive'? As I have put the new Contitech bag in and it still leaks. This is giving me the ****s. The RHS is fine, does not lose air. The LHS... Grrrr.
I have maybe 2mm of the 4mm protruding. Should it be cut flush?

1mm and cut straight with sharp blade, keep the pipe pushed against the bag while you tighten the connector

This might help if it is the same type of fitting:

If re-using old air line make sure the end is clean and un-damaged. If it has many score marks from previously being used then you may need to trim it back.

If using the type of Voss fitting shown in the video above then you don’t need to remove. You just remove the white plug and then when you push the pipe in and pull back it then bites into the pipe and locks.

The fittings in the Contitech are not push to fit, are they?

Should just be push to fit after removing the white shipping pin if it uses the Voss quick connect fittings.

They are not push to fit but compression type with "olive" as shown in the pic in my first reply like the one removed from the pipe in the video you posted

[DiscoDB]

The new Contitech air bags should have the Type 203 Voss connector which is push to fit.

The green blob of paint is to show it has been removed.

If you do remove it probably voids the warranty if it leaks.

[sierrafery]

Very strange... as long as that "olive" is supposed to get progressively tight on the pipe while the fitting is screwed in i dont see how it can be push-fit cos then the pipe would come out as there's nothing tight on it [bighmmm]

[DiscoDB]

The Voss 203 fitting has a grip ring that bites into the plastic when you pull it back and this then holds it in place. The sealing is done by o-rings.

It is probably a one use only type fitting once the pipe has been pushed in pass the “olive” if you then disassemble and remove the grip ring from the pipe.

Bohica would need to confirm if it came with the Voss type 203 fitting pictured above.

More details on how the fitting works:

In this case i stand corrected... what i know is that i replaced the pipes on mine long time ago to addapt T pieces for external compressor while the original factory fitted bags were on it, i didnt want to reuse the old connectors at the valves(which were the same with those on the bags) so i bought the ANR6460 voss connectors which didnt have that white bit at that time and the pipe was free to move untill i screwed in and tightened the fitting against the olive... the new bags were Dunlop with a different kind of push-fit connector(better type IMO as it has a release ring outside)

[Bohica]

I think I have the new Voss connector. It had a white part to remove, and a blob of 'witness' paint.
The instructions that came with the air bag had ".. installed in accordance with the OEM instructions... "
I'm glad I bought 2. One, I removed the connector. It leaks, the other one I have just pushed it in. I'll install that on the weekend.
As for the leaky one(s) I'll have to work out how to remedy that. I have a plan.

Hmm, I wonder if I can reassemble the connector and have another go.
At least now I know what was going wrong, I was getting very frustrated. I think these connectors have been this way for a while. The old bags have remnants of paint marks on them. The next trick would be to buy a pair of cheapies and see how long they last.
If the spring stays up I will be happy.

If you can get the grip ring off without damaging it, then yes you could try to reassemble with the white shipping pin, then refit the connector to the air bag, and then try again. Just make sure the grip ring is orientated the correct way as per the picture above.

Hopefully you have enough pipe free in case you have to trim it back to a clean/smooth section.

If it is leaking pass the o-rings it suggests the pipe may be scored or out of round.

Or the o-ring is damaged. I find it handy to lubricate the pipe and o-rings with silicone any time I disturb a connector. Makes it slide and turn smoothy on the pipe.

I can cut the pipe away from the ring grip. I,m not sure where I put the white shipping pins, I think I could put the ring grip in the correct orientation and position without it. Worth a try, before I go to plan B.
