I have been very interested in the posts concerning using the new hw piston seal in the tx 200, I would like to know where I can get one and what they are called, Thanks. Oh and how much money are they.

John Knibbs is probably the nearest supplier to you.
You need to ask for a 25mm Weihrauch HW77 piston seal, best to measure what you get as his grandson served me last time and when I got home I found he'd given me a 26mm seal.
I take it you know that the weihrauch seal will need an adaptor to fit the TXPiston ?
Think they're about £11.
Edit:-
Any problems with Knibbs and I'll let you have one.
All the best Mick

I didn't think HW did the new style seals in 25mm ?
(I'm doing the same as you)
You can get old design HW 25, or a VAC 25 from the US. Or a Macarri. I've got the latter en route, but I'm also trying to blag any old usable 25mm seal for a prelim test:

Unfortunately I accidentally butchered my Vac25 sizing it for a comp tube that turned out to be undersized (no biggy) and bulged (useless). So now it's undersize. Going to convert it to an o-ring carrier

you can't get the new HW seal in 25mm only 26 and 30mm which is a real downer
Vac25 is about the best seal right now for a TX or if you cn get one an LGV seal with a modified front seal face.
That's a shame, I am using o rings at the moment, but have an issue with them wearing out too quickly, I am using them from a cheap kit from toolstation, so not sure of the spec, going to get some nitrile shore 70 ones, or may try Viton as they have a better deformation set. Wanted to try the hw seal to see if it softened the shot cycle any, the old ones seem a bit too rigid for my liking.
