PTFE packing with Kevlar corner PTFE-packing with Kevlar Corner is braided with PTFE yarn with reinforced corner from Kevlar (Aramide) yarn, a combination of proved top qualities. High cross-sectional density and structural strength. It is recommended for piston pump in the universally applicable. This Packing is enhanced the lubricant of kevlar fiber and reinforce the strength of the pure PTFE silk packing. This special combination packing take a very important role for high pressure piston pump application. Temperature: 260¡ãC Pressure:4MPa PH range: 2 - 13 Density:1.4 - 1.6g/cm3 Velocity: 0 - 13m/s
