Spare o-rings for Atomic 2nd stage

[charlier]

I want to purchase spare o-rings the connect the LP hose to the 2nd stage (B2 and M1). I do not need service kits or B2 swivel kits, just the o-ring that is located between the 2nd stage jam nut and the LP hose. The part numbers might be 20-7150-00 (M1) and 20-2010-00 (B2) - fyi, I just need to right size. Most service shops do not want to hunt and peck, looking for the correct o-ring. thanks...

I don't think there is a ring between the LP hose and the jump nut. For sure not on M1. For B2 with swivel, I don't remember, but still don't think I saw one.

If you unscrew the LP hose from the 2nd stage, you should see an o-ring. I will take a photograph...

I don't think you need the o-ring between the jam nut and LP hose as the one inside the LP hose will make the seal. I don't use one.

I think the one for the atomic swivel hose is needed though.

As others have said there is no o-ring between the jam nut and the lp hose on the inlet tube. The o-ring is on the LP hose and seals on the inside of the inlet tube.

20-7150-00 - this o-ring is for the orifice
20-2010-00 - this o-ring is for the LP port plug.

If you have a swivel hose then yes there is an o-ring 20-2013-01 that goes on the inlet tube but then there is no jam nut. If you have swivel hose, o-ring, and a jam nut well then it is fubar.

It's probably a what, -013 oring?

Too be honest I am not sure if there is any correlation between AA part number and the actual o-ring size.

 

[guruboy]

I don't think there is either. I was just taking a ballpark guess based on what I remember.

Its seems that my post was lacking clarity, but SS graciously answered the post. Agreed, the jam nut is only on the M1 and the B2 swivel uses an o-ring, 20-2013-01 (no jam nut on the swivel).

Do you know the o-ring size or equivalent?

I do not but I have those o-rings and can measure some for you - only problem is will be in a week. So send me a PM so I remember.
