Does anyone service them or are they normally just replaced?
Nick Murphy (Zenith) did a great job on mine.

Cheers. Just did one myself, a bit of an experiment to see if I could save it. It seems to have worked ok. Hadn't heard of them being serviced before, only of being replaced with a Huma or Lane reg.
never seen one .
are they similar to the ev2 ?
yes from what I seen
Similarish. But a lot of regs are. The piston is larger than the EV2 and has a very blunt nozzle end to it and the sealing face (doesnt appear to be delrin, no idea what it is) is domed and recessed so cant really be refaced. I had to make a new seal for it and put more of an edge on the piston, which was the experiment, firstly to see if I could make the part as I dont have a lathe and secondly to see if it performs. I'll put some pics up later.
A few pics for the perusal of the geekiest.
As it was, untouched from the factory.
Does Brass piston tip go all the way to the edge of the plastic ?
Not quite, it's not far off though.
I imagine the domed seat was devised in an effort to overcome what has always been the weak point of AA regs, creep.
The knife edge on the piston rod of the Pro-T and EV2 regs eventually leaves a witness mark on the nylon / delrin material in the adjuster screw, to the point where air can still pass though. Part and parcel of any AA reg rebuild has always been to remove the witness mark completely, otherwise the reg continues to creep.
What you have done looks really neat, and I am sure it will work well, but you will have to make a new nylon insert every time you service the reg, this may well be the case with the factory reg, I've not had one in bits yet, if it is then you have managed to do away with the sole reason FTP regs are binned and not serviced, well done.
I have a cunning plan so I dont have to make another seal from scratch. It should work ok, a bit of testing will be needed first though.
Sounds go0d. Let us in on the secret if it all works out.
Far too many people bin the FTP reg when they really could have the thing rebuilt.
