Piston seal on a German Beeman 124

Ill assume this 124 is the same gun.

Days first gun to use a synthetic seal but they stunk. Modern seals for it are good to go.

If you can glean any info from this may help . Looks like once your old seal is out you just push the new in like a plug.

Thanks to all that answered! I’ve all ready cleaned all the old deterioated seal out of both piston and inside the tube, if that’s what you call it , a thousand pieces! ,but I don’t think it was leather?the new one has’nt arrived yet , the picture look like synthetic . What was left in the piston looked like it mite have been locktite? I’ll try to take photos tomorrow, thanks

"Great Gobs of Grease, Batman" look how much grease he globs on the bellville washers.


Why did Batman RUN to the Batcave?

He had to go to the Batroom!
Lol.. i know right? Just what he has on the seal could do 3 complete springers properly..lol.

All his jobd are that much or more . He must have a 55 gallon drum of moly he needs to get rid of..lol
 
Ok .... on 124's the seal is pressed INTO the pistons nose within a counterbore. there is a radial GROOVE at the bottom that MUST BE 100% cleaned out !!
From there a small daub of lube on sides of the counterbore and on the tail of seal. Place on a firm surface held vertical and FIRMLY push piston down onto the seal until all is flush with back of seal being against front of piston. Next .... SIZE and fit the seal to deburred comp tube.

I was wondering if you put that seal in the freezer to maybe shrink it 100,0000 or even help stiffn it then lube the anchor tail end with good slick owl snot stuff then maybe easier to press in? Dont know what the tolerance is on ot to the hole or if it mushrooms out trying to push it in the hold as is room temp .. lol.
 
Who'd you get the seal from ?

Just refound this on the seal being the first (just s little extra fyi)

" The legendary FWB 124 was one of the first airguns to use synthetic parachute piston seals. Unfortunately, they used the wrong formulation material, which disintegrates over time. These are totally useless, having turned to the consistency of hard wax over the years. Modern replacement seals for 124s are made of much better stuff."
