What is this part?

[e30Andym42]

I have researched and researched and I cant find it on realoem.  There's no part number on this and I busted it in two pulling the hose off.  Please help!  It's the gray plastic piece forming a 90 degree angle on the hoses



I saw another post which Dave said he thought it was a non-return valve.  Part #13 http://www.realoem.com/bmw/showparts.do?model=AC95&mospid=47277&btnr=34_0700&hg=34&fg=25.  34331154771.  But it doesn't really look correct in that diagram.  Mine is connected between just two hoses, where the diagram appears to be designed for 3?  I can't find an actual picture of that part number. 

Also, if this is just a brake booster check valve, would it be feasible to replace it with this? http://www.ecstuning.com/BMW-E30-318is-M42_1.8L/Search/Booster_Check_Valve/ES61684/  It would certainly save me money.

Had a very hard time finding that part, at least the one with a 90 degree angle. The check valve you have is original and is NLA.
Here is a link to where I got mine and it's working like it should. http://www.autopartsway.com/PartDetails.cfm?W0133-1899667/OES

You may also need elbow 34331158930, gasket 34336765316, 4 15-19mm hose clamps, and some sturdy 1/2" air hose (available at truck or industrial hose shops).

Thanks for the reply.  Glad to see there is an option with a right angle still.  I'm currently going turbo, so the angle may not be a necessity.  I'll see what'll work best for me.  Thanks a lot!
