You don't use an O-ring here...

Thanks Stuart!

One last question on this - what size o-ring fits on the bottom blanking plug, in case I need to replace it?

[Brooksy]

If the bottom blanking plug I ring is crushed, leave it there and use the Dowty washer from the adaptor.

[Ca_Varminter]

All of mine from the Theoben has been a Dowty washer.....
The only one I have seen that use an O-ring is Dr Bob's slimline blanking plug!!!

Thanks!

The bottom blanking plugs I bought from raw in the theoben spare parts section has Orings not dowty washers, they have a groove machined on the flat part with an oring

I found an old post that states that it's normal for the plenum to degas if the pressure is lower than the reg set point.  Is this true?

Thanks!

[Ca_Varminter]

Yes....
It is called...Falling off the Reg....
Since there isn't enough pressure to close the Reg..
It will Free Flow...

Thanks for the confirmation Stuart!

Just as follow up, I bought the HUMA gauge that is supposed to work with the RAW HM1000X rifles.  Unfortunately, this gauge doesn't work.  The tip of the threaded end hits the reg before it can screw in all the way.  It only screws in as far as the red line shown in the picture.

I had to spin my adapter down in the lathe so that didn't happen

[Ca_Varminter]

1/4" bspp to 1/8" bspp adapter... Hose and gauge

screws into the bottom blanking plug.....

Stuart

From my earlier post.....
That is why I went the hose route....
The 1/4" bspp fitting doesn't protrude that far into the receiver to interfere with the Reg.
