Just had an email back from Vortek saying they are working on a 'O' ring piston head fitting for the Weihrauch range, presumably like the AA ones they sell but without the big 'ole in the middle, that a muggle like me can just heat with a hairdrier and pop onto the piston like the OEM job.
They also said they could not guarentee they would perform better than the parachute types they make already. So there's honesty for you.
Thought I would let you know, thats all.....

he has been at this one for a while now...not sure what you need a hair dryer for, vortek seals just pop on quite easy, well they do for me here

I'm just waiting now for all the ******** to turn up and say that "O rings are old hat and don't work"
LOL
I have several HW's with O ring conversions and they are amazing.
My 1966 HW55T is currently away having the same treatment.

Opportunity is missed by most people, because it is dressed in overalls and looks like work.

Matty, the bonus the Vortek conversion has is that is is essentially still a synthetic seal, so it gives the soft shot feel such seals give BUT if flies faster as an O ring is doing the sealing with less friction. So, you gain power and you gain the soft shot feel...so it usually is a win win using them.
Plus on the 55 the old seal is 11mm tall, the new seal you are using is 6mm tall, so you gain around 5mm stroke, which is enough to push the gun to 10fpe with out having to use a harsh spring. My 55 is so easy to cock it feels like it would never do 6fpe never mind 10.5fpe.
O rings are fine, as long as the transfer port is small enough to allow piston braking but large enough to allow good flow.

Of course they work. One large volume spring air rifle manufacturer used them on piston heads for all of their models for a considerable number of years. Different power outputs over the range of guns. They used big and small transfer ports

I have 8 AA Sidelever Springers from the 1980s all of which run very nicely on O rings
But there are people who vehemently insist that they are out of date and should not be "revisted"
Can you believe it?

Everything goes together much easier with a hair-drier! Good for heating metal prior to dri-slide treatment too.Al's workshop is a bit different to yours and mine... hairdryer, curlers, tongs, little bits of foil and bleach (showing my own expertise here
Jackals were just nasty steroided versions of the lovely Hammerli sidelevers. If that rifle had been correctly redeveloped it would have been brilliant.
