Lee p15 plenum extension o ring size?

[kzz1kaw]

Anyone using lee’s plenum extension now what size the o ring is? Is it a buna n70 or 90? Cannot not get the airtube to seal. If you have lee’s ph # can you pm me. Had it at one time but lost it. Have his email but has not answered my emails😳 btw picked up a 22 and will need another plenum extension. Does he have a website or is he sell his plenums on here? Thanks

Hi Ken,

I have one from Lee, from memory it screws straight onto reg and into valve housing, if you cant get one from Lee, I have been doing some work and testing of Huma's new Power Plenum, this is available now and includes a Huma Reg...

Hi mike
I saw them on huma website going to get one for the 22 but for a 25. I have one of lees plenum on my 25 and there is a O ring just don’t know if it is a buna type 70 or 90 o ring or the size? Hoping someone will chime in or pm me lees phone number

Ken, my guess would be 20 mm ID and 1.5 mm c/s cross section. I just measured my spare reg and plenum, so it is what I'd try
I would use 70d buna for sure

I just had Lee545 do some work on my Skyhawk, he is working a lot of overtime right now at his main job, but he answered my Airgun nation PM’s with a week or so delay.
I do not have his phone number, if you paid for that  plenum recently with PayPal you have his current email.

I had Lee seal up my Skyhawk 22 as I had run out of divers grease trying and  I just could not access the correct orings around here. Add to that I am legally blind so it was over my head at this point on my trail.

Lee sealed it up on the first try.

Now about that oring, it is the same oring that seals the Huma to the valve body, IF you using a Huma reg, if your using the factory regulator all bets are off, but I suspect smart money would say it is the correct one.

Good luck on the plenum instal, the rewards are impressive, I am making 46.6 FPE with my Skyhawk now.
