yes they do. its the one on top left hand corner


and u better belive me
BTW these 50mm WG never really fails

 

Do these WG's use the same springs as 35/38 ssac gates?

Serious or sarcasm

 

they use different springs.

Trust me i use to work with these crap everyday. sold 500+ with ZERO complain throught the two year.

 

The stupid thing that happened to me with one of those is the flange with the seal ring on it, I was NOT ABLE to weld anything on it !!!! Checked with a magnet, it's magnetic, there's iron in there, but All the weld would spit back in my face leaving nothing but a porous gouge ont the flange!!!
it was just like trying to weld aluminum with a mig rigged up for steel. Very Weird....

oh, and does the suipplied gasket fit around the ring? I suspect they send the same gasket for both the 46 and the 50 mm wastegate but this gasket works only on the 46mm...
