An Airgun O Ring database

[Phil Russell]

Hi Phil,

Can I add this chart for the Falcon FN series:

and please let me know if you want this thread moved to the 'useful' section? http://www.airgunbbs.com/forumdispla...-Shooting-Tips

Hi Rickenbacker
I have no objection at all to you adding to the thread nor of moving it to a better position. The thread is there for peoples' information and I am very happy for it to be put where it can do the most good.

Cheers, Phil

A&M Cylinder Fill Probe (HW100) 4mm ID x 2mm thick.

At least now it's recorded here I'll be able to lose the bit of paper I had it written on without beating myself up too much over it.

This thread's going to become increasingly useful the more it gets added to, but at some point someone will need to consolidate the data, tidy it up or whatever.

The O ring supplied with my HW100 Huggett shroud seems to be 14 x 1.5. Note that's different to the 13 x 2.5 listed elsewhere in this thread.

I will do my best as and when data are added. I have not done the Falcon table as I expect it is fine as it is. As for the HW100 Huggett shroud, I have added your measurement but could not find the 13 x 2.5 item ... maybe a senior moment? (mine!).
Thanks for support, Phil

Loading Bolt Probe O-Ring CZ014 3x1mm (.22 & .177)

Airtube seals 21x2 mm

Seal at firing valve end 6.5 x2mm

Magazine pellet retaining rings .177 12x3.5mm & .22 11x3.5mm

I'm finding the Simply Seals site very useful and very good value with the proper grade of NBR for us i.e. Shore hardnes 70

OK, here goes. After spending ages trying to get this info, surprised nobody has posted it before, here is the list of seals for the Brocock Enigma in .22. All are imperial sizes. Please decide on each section before just buying (I thought the seal kit available was very expensive so avoided that route). I have a friend who owns a seal company and we went through his boxes and found the right ones for each.

Action chamber seal for high pressure cylinder inlet - BS615, though this is quite a special size. My friend didnt have any so I used a BS112
High pressure reservoir seals (x2) - BS213 officially but I found a BS212 fitted better
Gun barrel seal (.22 - not sure about .177) - BS009
Grub screw on underside of action chamber through which the transfer port is drilled - BS009
Fill valve metal bonded seal - 1/8" BSP Dowty seal
Fill valve check valve o-ring - BS004 supposedly but I am in the process of re-engineering mine as I dont like the way the o-ring sits (pic below of modified version - used epoxy on the shaft and put it in a Dremel type tool to machine it to a better fitting size)
