[sharpshooter]

What # oring goes on the very top of the gen4 brass popitt? the manual does not say since it was an upgrade part made after the typical delrin model

Try orings tell you find the one that works.

By top are you referring to the o-ring that goes inside the rocket cap?

No dude the brass popitt...you know the brass popitt?? it has 3 orings,a #006 that goes on the very bottom stem,a #010 u cup that goes on the middle but i learned that a regular #10 can be used...and then on the very top of the drum on the popitt there is a oring around it and the manual does not say what it is??

Also do you have a oring on the ram where the rocket cap screws onto?? because one of my ram housings cam like that and another did not and i heard that an oring does not go there??

as far as trying orings untill i find the right one??Thats hardly the way it should be done...many leaks and lots of trouble...lol..im sure there is an answer to this

Not sure off the top of my head, but the stem o-ring is a 004. The back might be a 009.

I thought the very bottom stem oring is a #006,and for the middle you can use a regular #009 instead of the #10 u cup....it is the very top oring i dont know what it is??? it is the one that goes around the fat drum at the top of the popitt

What does the manual say?

What does the manual say?

Well like i stated the manual says,that the stem oring is a #006,the cup seal oring is a #10 U-CUP,and thats it since it is referring to the old standard delrin popit as i imagine...but i have the new brass one,so i dont know if the usual #006 that the manual calls for for the stem goes to this brass popit? i think it does since this oring is to match the inner diameter of the valve guide,and after fitting #006 to one of my brass popits.There seems to be no problem.I used a #9 regular oring for the u cup seal and although i have not aired up the gun yet since its not finished,i dont know if it works yet.However there is this oring on the very top of the brass popit head...around the large drum that the manual does not talk about since the delrin popit had the delrin head and used itself as a sense of lubrication.

Not to have the brass head reciprocate in the rocket cap,it is surouned by an unknown oring

And yes the oring that goes inside the rocket cap.You know when you put the brass popit inside the ram housing? and now you just see the fat top or drum of the brass popit?? and there is a oring right on the top of the brass popit,that the rocket cap will now screw on top of? and the inner bore of the rocket cap will go on top of that oring?? thats the one...since the manual talks about the stock delrin popit...it did not need and oring since it was delrin...since this popit is brass you dont want metal to metal so there is an oring on top of the popit
