How Do You Seal A Leaking Set Screw Huben Dream Valve?

[Hate The Rain]

Just replaced the plenum o-rings in my Huben Dream Valve 7075. Had another problem that I posted earlier and that seems to be cured. One of the 4mm x 4mm set screws at the plenum swivel was leaking before the new internal o-rings and is still leaking after their replacement.

My fingers are to fat to be able to wrap the set screw with teflon tape. My guess is that there shouldn't be any air where the set screws are located, but the o-ring replacement didn't slow down the leak at all. It is only leaking from 1 of the two set screws. I am contemplating taking it apart again and tapping the hole to a larger set screw and see if that will stop the leak.

Does anyone have suggestions for curing the leak?

Thanks

Permatex, lightly and dry

Must be a leak somewhere else. Those set screws don't see air pressure.

Thanks for the replies. I think I will take it apart again and really inspect the plenum inner two seal surfaces and see if there are any flaws or cracks. If nothing, then I'll put new orings in again, and try the permatex route. Beginning to think I got a lemon of a Huben Dream Valve.

Thank you. Have worked that direction. Can't remember my order number from December, I found there invoice and charge to my cc and passed that along, but no progress made. They seem a little hesitant. Guessing they think I bought the Alibaba version. Even though I just purchased and received another cricket valve from them. Oh well, half the fun is the tinkering. I just hope I can figure out what is causing the leak. Would hate to think I wasted $180.00. Thanks for the suggestion though.
