PTFE hose type NFR-A
The PTFE hose type NFR-A features rugged stainless steel braid. The hose liner consists of seamlessly extruded PTFE with an electrically conductive design; this makes the hose suit-able for use in areas with a risk of explosion (EX zone 0). Thanks to these components, the hose guarantees high chemical resistance, thermal stability and elasticity, as well as weathering resistance. Our conductive convoluted PTFE hose with its stainless steel braid is used in applications that require outstanding heat resistance. In addition, the hose is very flexible and offers high resistance to solvents and other chemical substances. We can offer a variety of fittings and materials for all our PTFE hoses and are pleased to respond flexibly to customer requests. Complete traceability is ensured by the serial number on the crimp collar.
