Thanks Dave. I will have just contacted Airtech and hopefully they will reply soon. Or I may have to get the seals from you. It sounds like you do not have the O-ring size? I could pop it back out and measure it but I'm not sure I can measure an old O-ring accurately.. Those rods are not shiny smooth, and we fly in very dusty conditions here in CA, so wear is surely a by product.
