SAE 100R14 The PTFE hose core is manufactured from PTFE. 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 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. Smooth Bore HoseAll of the hoses in the following range are fully approved to the SAE specification and are available from Pacific Hoseflex today. We feel that this will become the global size range for PTFE hoses and recommend that your smooth bore hose demands are selected from this range. If the coupling size restricts your choice we have three further ranges of smooth bore hoses for you to select the exact size that best suits your requirement. The standard wall products are not recommended for steam-cold water cycling.
