Elite Pressurized Tube
From Feed The Beast Wiki
Elete Pressurized Tubes are very similar to the Advanced Pressurized Tubes, the only difference is the amount of gas transported. They work very similar to BuildCraft's Fluid Pipes except that they cannot transport liquids but gasses instead. Advanced Pressurized Tubes are also ForgeMultipart compatible so they can be used with covers and other Microblocks.
