PP700 Probe O-Ring Size?

[Kid.Shelleen]

I'm trying to find the correct O-Ring size for the fill probe of an Artemis PP700 pistol. The only thing I have found so far is 1.5mm x 4mm (Cross Section x ID). That sounds a little small from the rough measurements I took from the torn one on my probe. Thanks for the help.

Going from memory, they are M1.5 x 5.5. Meaning an OD of 8.5mm (0.335in).

I will check my records later if no one has replied. Or if you have calipers, measure the probe OD next to the O-ring groove and post it.

Looks like your measurement is correct. According to Matthias in the following thread, it is a M1.5 x 4.

I would go with 70 durometer.

Yes, that is the size for the breech seal. The pp-700 does not have a probe.

Mike, by “probe” he is referring to the fill probe, not the bolt probe or breech seal.

LOL!!! I knew that there had to be a catch. LOL

Thanks for the replies. I saw that link when I did my original search here. The 1.5 cross-section seemed close but the ID of 4.0 seems small. I was rough measuring an ID of something close to 5.0 mm. The OD of the 1.5 x 4 mm is 7mm. I measured the OD of the probe and I got 6.99 mm. I'm almost thinking that the 1.5 x 5.0 may be closer. I went ahead and ordered the 1.5 x 4 mm (70 duro) since that's what was listed in the referred link. I should be getting them tomorrow. I'll post back with the results.
