Air Venturi Avenger air leak problems?

I agree, I think it's a compromise for an aesthetic. I just put calipers on mine to confirm the 20mm measurement, but I wanted to mention that I used the nearest fit SAE size in my impact socket kit, 13/16", and it worked perfectly. It took a considerable amount of torque and it broke free with no spongy precursor to rounding off the ends of the flats, so if you can put your hands on a 13/16" you may want to cancel the special order 20mm.
 
Well I received my 20mm 6 point socket, today. I sanded most of the chamfer from the end of the mouth so
it would fit deeper over the flats for better grip. Worked like a charm. I pulled the fill chamber off. Yep like
was said by one of you the Oring had gotten very hard. I,m hoping my Oring set from Capt O ring will arrive
tomorrow. I plan to just replace that one first & see if it whole pressure, just out of curiosity. Even if does,
I going to tear it down & replace them all. I will report back on that. I know this thread is long. But I posted
it in it,s entirety so someone will be helped. That’s what this great form is all about. 😃👍🪰Fly
