Conductive PTFE convoluted hose
PTFE CONVOLUTED HOSE TYPE NW-A
Our conductive PTFE convoluted hose is frequently used where special pressures are not expected. Typical applications include suction hoses for sampling, emptying barrels, or conveying gases and vapours at low pressures. The hose liner consists of seamless extruded PTFE with an electrically conductive design.
PTFE convoluted hose type NW-A
Our conductive PTFE convoluted hose type NW-A is suitable for applications in areas with a potentially explosive atmosphere (EX zone 0) and, like all our hose assemblies, is manufactured to the highest quality standards and from carefully selected materials. This ensures high reliability, temperature and chemical resistance, and low weight with maximum hose flexibility. The wide convolutions ensure good self-cleaning properties when routing media. Our PTFE convoluted hoses combine optimum flexibility with easy handling. We can also offer a variety of fittings and materials for all our PTFE hoses and are pleased to respond flexibly to customer requests. In addition, our convoluted PTFE hose type NW-A can be designed with smooth cylindrical ends. The serial number on the crimp collar ensures complete traceability of our hoses.
