Parker Page HoseParker PAGE International Hose’s STW and STB True Bore Hose Assemblies have a larger inside diameter to speed up the flow of the media through the tube. Unlike standard hose assemblies, made to nominal bore sizes, these larger diameter hoses carry up to 15 percent more flow. This product is also available in a heavy wall variation, resulting in 33 percent more PTFE. The additional tubing thickness provides an improved bend radius, greater kink resistance and reduced permeation. The STW and STB True Bore assemblies are manufactured in sizes from 1/8 inch up to 1½ inches ID. Static dissipative assemblies can be provided upon request. – parker.com
