winchester 1100 seals

[WxRadarman]

1st time tuning my Bull Whisper and 1100SS. 

Ordered seals from Air Rifle Headquarters.  The seals for the Bull--Gamo Tesla Custom Piston Seals fit perfectly, but the ones I ordered for the 1100 are too large -- Tesla Large Seal- Amazing Quality-RWS ETC.

What is the correct seal for the 1100???

That's a good question, Keith.

Thanks for the tip on the hidden allen screw by the way - between you and Dave, I was able to get mine open.  My seal measures 1.062, the tube is a few thousandths smaller.

That makes the ARH APEX Small a bit too small.  I wonder if the ARH Hatsan 1000 seal will fit?  It's the right OD but I don't know about the ID.

So... The ARH Hatsan 1000x seals don't fit very well.  The base diameter is about 0.100" too big.  I think it will go on but fit will be sloppy.  May try it anyway after the piston is all cleaned up and ready to go.

Anyone else have any luck finding a replacement seal for these chinese Winchester 1100s?

Found the correct seal:  HAT95

Installed today and it fits well.
