Quickswitch rebuild/O-ring sizes

[XEMON]

Hello MCB,

I am trying to rebuild a PPS Quickswitch.

From the PPS website i have this:


So:
- cup o-ring: 046
- stem o-ring: 003

Seems easy right? well ... not so simple ...

According to standard sizes, here is the actual 046 o-ring description:
#046 4-1/4"ID x 4-3/8"OD 0.070" (1/16" Width)


I tried 008 in there, but they are too big a shred upon installation.
So, what is actual cup o-ring sizes?


Edit:

Thanks forumreader for solving the mystery:



Tanks yall for the help,

So I have this written down from a blazer. I am assuming they are the same, if someone knows differently, please let me know so I can update my records.

046x.224 for the switch cup oring 70 durometer

[XEMON]

The y are the same, but o-ring 046 is over 4 inches in diameter ...

Craig himself chimed in a few years back on the old mcarter about this issue. The 46-224 is not the same as a -046. It is a weird seal and nobody knows where to get it but those named Palmer, unfortunately.

Fortunately, Craig shared an alternate size that is obtainable by us mortals. It is a 1.2x5.7 metric oring. I have purchased many and used them to rebuild a few blazers and quickswitches with great success. You can purchase them here

Awesome, thanks.
Ill get a few of those.

Great information, I will add this to my notes.

Ok, I found an alternative for the cup o-ring ... Seams to fit great.
but as I was putting it back together I noticed the 003 o-ring in the stem are nowhere near the inside of the cup ... There is a big ole gap between the stem o-ring and the inside of the cup ...

Those 033 o-ring have been working great in other 3-ways.

Do I need a new set of cups at this point?

[XEMON]

Look at that big ole gap! ... No wonder it doesn't hold air ...
(That's with new o-ring on the stem ...)

I have had that problem with 003 orings before, I find they're not always very consistent in dimension and have gone through 5 or 6 to find two that fit whatever 3way I'm rebuilding.

[XEMON]

Good point, that bag is pretty consistent ... I got it because my old bag was all over the place ... Time to digg the old bag out ...
Thanks

I just finished doing my Blazer switch rebuild and used 005-70 orings stretched over the cups instead of PPS spec seals, seems to be working.

I plan on ordering a rebuild kit at some point but didn't want to wait a month for it to arrive, given the state of the postal service currently, so I thought I'd try something from a local source first.

edit: I used 005's (corrected initial post) and have, since the initial rebuild, installed urethane 003s - makes for a much smoother trigger actuation.

Thanks be to MCB yet again. This thread is relative to my interests.

Item # 46-224, O-Ring, 0.046 C/S x 0.224 ID x 0.316 OD - nitrile 70D

For future reference

Something I would like to add to this post is that I believe there are different stem and cup sizes. I’ve ordered an extra stem from PPS and it didn’t fit inside of the cups I had at all. It was far too tight and would hardly travel through the switch. Also the 003 buna N o -rings are far too small and will leak compared to 003 polyurethane o-rings. The Palmers switches are all pretty much set up for polyurethane o-rings unless they’re custom made for buna.

So i am rebuilding my quickswitch. Thought i was golden, then cleaning up i found this clip in the pile of destroyed orings. Not really sure where it came from. Anyone got any idea?

[Jordan]

I've never seen a c clip like that inside a 3way. It looks like it came out of an Xvalve, tbh.

[SatrNfReak]

So i have had an ANS Jackhammer, and an Air America Vigilante apart on the same bench. My eyesight is not what it used to be, so maybe it came out of one of them? I sure didnt take it out or had to hammer anything apart..... Now im just wondering if it was floating around on the bottom of something ...

[SatrNfReak]

Ive had this gun apart a million times when i was younger(except quickswitch), and never came across this....
