Does anyone know of a high temp (300°C) low pressure(90psi) piston seal? It will be used in a low velocity piston and must be able to hold pressure as well as move with relitivly low friction (im hoping to use aluminum components). I have an old Variseal catalog here at work that came out back in 1996, but the seals that I found are apparently now longer carried (M18 200 series). Any thoughts/suggetions would be great. Thank you much!!!
