Strut/airbag not a good design?

[xRide]

I am getting ready to undertake the job of installing new front bags.I got only the bags from Arnott, not the entire assembly. I am reading the instructions and there is a part that says you should make sure the "lip is seated over both o-rings properly or else the bags won't inflate. Now im not sure how the OEM one is designed, but im thinking that if im going to design a part like this, I would design it in such a way where only the nozzle for the air supply gets exposed to the outside world.....As in...the only way for the air to escape the bag is if i remove the hose/connection to the air supply from the bag.....not because the "lip isnt seated correctly."

now..im no designer so excuse my ignorance if theres any.

They probably had to design their replacement to fit the OE BMW air strut assembly, so I don't know if its Arnott's fault.

Regardless, this is why I bought the remanufactured air struts when I replaced mine, so I had the new bags installed already and it was just unbolt, unclip, drop out and swap new ones in, and send those m'fing cores back to Arnott. No worries about improper install of the new bags on the used struts, etc.

Good luck OP!
