MEDIUM PRESSURE SMOOTH BORE HOSE
Our industry standard is CH67. It has been widely specified for an endless variety of applications including automotive, food processing, pharmaceutical, chemical and petrochemical.
Our hoses can be found in factories, on trucks and buses, on automobiles (both on and off road), in laboratories, and in endless manufacturing situations; anywhere that the limitations of rubber, metal and synthetic hoses make PTFE hose the only solution.
Some applications require a conductive inner liner to dissipate static electrical charges. High resistivity fluids or gases at height velocities cause positive electrical charges to build on the inside of the PTFE liner. If not dissipated to the end of the hose, the charge will build until
it arcs through the tube wall to the braid, causing catastrophic hose failure. To alleviate this, Conrad manufactures a heated hose assembly with a thin conductive liner on the inside diameter.
Temperature Range:
-100ºF to 500ºF (-73ºC to 260º) Intermittent Service
-65ºF to 450ºF (-54ºC to 232º) Continuous Service
