Jim tell us what you are trying to do
I need to replace the seal on the face of the valve, surrounding the piercing pin.
You will probably have to deal with Canada for this. @wesbob https://airgunarcheryfun.ca
And remember, Artemis is another brand name for Snowpeak
reality
those seals are very hard to find i found some great looking custom seals in the UK but they don't ship out of the UK
i have sent them an email to see if that could change and the answer is crickets so far
Search - Tag - cp2 (nmproducts.ltd.uk)
price is fine shipping should be cheap because Knibbs and Chambers and Protek shipping costs are very fair
so that is what i found
One of the folks on the GTA had the same problem. I believe he had success using a 90D 009 O ring.
after looking at the seal the 009 might work
i have many Orings but no 009 so i could not fit any
the flat seal that a Gamo R-77 pistol uses is a perfect fit but a little thin at 1mm
the seal that is in it is 2mm but has a pocket in the face that is more like 1.5mm in thickness
8.5mm to 9mm would be fine for OD
the Gamo has a small ID hole and i tried stacking 2 together but the piecing pin was not sticking out very much meaning you would have to crank down the cap to pierce the cart
i don't know but i will tell you this chasing parts deal is getting old
Not at all like sourcing Crosman parts is it.
Another thing to try would be to call Pyramid and ask for that seal for a Diana Trailscout which I believe is another variation/brand name of the SPA 600.
the Chaser or Airbug or Trailscout would all have the same seal
years ago i contacted PA about Chaser parts and Air Venturi was the importer and i contacted them and they could not find their pockets if their hands were in them
finding parts in the states is a joke for most guns but in the UK they have 4 or 5 companies and we have at least 3 to get parts
this thread has been where to find the parts and i solved that but the parts are in the UK and will not ship
so, now i am working on o seal substitute
i have some 009 Oring order and they will be tested
this is no different then finding an Oring to replace the seal that the IZH 46m uses for their special breech seal
the seal that is used for the CP2-Chaser is 8.5mm, id big enough for the piercing pin but there is pocket in he middle that would bring the thickness from 2mm to 1.5mm it fits in the ring that screws into the valve
this at this time for me is a work around
after some back and forth it appears PA is the Importer for the Diana Snowpeak products but i could be wrong
there are 3 different names at PA with Snowpaek products
Diana
Seneca
Air Venturi
Jim, have you tried contacting Mike at Flying Dragon? He might be able to point you in the right direction for one.
the seal on the Snowpeak products look like they seal on the neck of the cartridge vs like a Crosman on the face
the Hammerli 850 seals on the neck also
i will have the 009 Orings to test, they are not Urethane but they will work for testing and if they work the Urethane Orings can be bought at the Oring Store
there prices are fine but there shipping charges are out of hand, i am guessing there shipping costs and filling the orders are combined
just installed and 009 buna 70dura in a Chaser tube
the Orings were chosen only because they were cheap for a test urethane would be my choice always
cart was pierced and no leaks
tube and with cart weighed 13+ oz will check tomorrow and see if the weight is the same
if the 009 Orings will work which it looks like they will that problem is solved and cheaply
the Oring fit in the threaded collar very well
will post tomorrow and if the weight stays the same the test will be over
mike
as an old reader and poster on The 850 forum i was taught that Urethane was the way to go when CO2 touches Orings
will others work YES but if Urethane can be found use them and in this case Urethane Oring can be found at the The Oring Store
i had checked and no leaking so that is good news
i would also like to try Gamo R-77 flat seals i know they fit but are a little thin

Mike,
Thanks for your usual deep dive into this. So based on your recommendations and testing, I'm going to order some 90D BunaN and 90D urethane o rings in size 009.
the 009 seem to be working but it is one day
i did it because there was a question and i needed to know for myself
Given the fact that it appears to be a neck seal vs a face seal, I opted for 70D urethane, and skipped the BunaN due to the 100 pc minimum order. I love/hate the o-ring store.
it really isn't a neck seal like the Hammerli 850 or a face seal either but it is a seal that works fine
we as owners and hobbyists we have to R&D work arounds sometimes when the manufactures and or importers are completely oblivious to the needs of the owners
i am i detailed oriented type of person and it pisses me off they are so lazy
Sorry I'm late to the party but I just wanted to confirm a -009 seems to hold up well. I had to search up my old GTA thread to find it was 6 years ago that I repaired my SPA CR600W (Mrodair Plinkster). Earlier this spring I loaded a cartridge and it is still working fine.

Thanks for the reply and the link. Seems Plinksters have fallen off the map. I still love mine! I'm waiting on 009 70D urethane o-rings for the rebuild. Gotta get her healthy again. What a fun gun!
Successfully resealed. I used a 70D urethane 009 o-ring on the valve face. If I bottomed out the brass retaining ring, the o-ring would squish out, so I just snugged it up to the point before it distorted, and lock-tited it in place.
The unusual rear sight placement is due to the fact that the Williams peep interfered with the bolt action. I put it on the front dovetail, and switched from a .050 to a .150 aperture. The sight picture is almost identical.
The front barrel band came from Buck Rail, but it was a two-screw with a Weaver rail on the bottom. I cut it in half and ground off the rail.
The gun has a Steve-in-NC trigger and FFHDD. It’s light, quiet, and accurate. Love it.
