TEFLON (PTFE) HOSES WITH ONE S/S WIRE BRAIDED COVER
The PTFE hose core is manufactured from Teflon. No pigments or additives are incorporated thus giving the hose liner a translucent appearance free from any contamination. The wire braiding (1 or 2 wire available) is produced from AISI 304/S15 or BS970 1970 quality hard drawn tensile stainless steel wire. Reduced static versions of all hoses are available for applications where electrically resistive fluids are being transferred at high flow rates. The standard wall products are not recommended for steam-cold water cycling. We recommend the Heavy Wall range for the most demanding applications including intense thermal cycling.
