Baileys are not ideal for turbo minis.... the rubber seals don't like fuel or something like that?

I've heard that the piston can become contaminated causing it to stick, most people seem to use the diaphragm type on the A-Series.

I had this problem with my bailey dump valve, the ruber seal grows for some reason, my got to a stage where it would never close, so I had to bin it!

I think the rubber seals swell up a bit because of fuel contamination!!!!!! But it is possible to get special seals that dont react with fuel.

the standard seals are made from nitrile which reacts with the fuel causing them to swell so the valve siezes. The seals needed are made from a material called viton.
