Parker's Chemical Resistant PTFE Smoothbore hoses have exceptional chemical compatibility and handle temperatures as high as +450°F. 919/919B assemblies are used in numerous applications including, but not limited to, chemical transfer lines, high temperature general hydraulics, and coolant lines. The PTFE core tube resists moisture and offers the lowest coefficient of friction of any known plastic, therefore minimizing pressure drops and deposits. PTFE hoses are less susceptible to cracking from stress or flexing than metal hoses. The 919 hose meets SAE 100R14A and is constructed of a natural FDA compliant PTFE tube while 919B hose meets SAE 100R14B and is manufactured with a black static-dissipating PTFE core tube. Parker 919B should be used when conveying non-conducting fluids such as oils, paints, fuels, or steam. Parker’s 919J PTFE Hose features an extruded silicone jacket to provide a clean, smooth cover and 919U features a non-marring, abrasion-resistant polyurethane jacket to shield the stainless steel wire reinforcement against wear, fraying and contaminants. Both of these hoses are constructed of a natural FDA compliant PTFE core tube and reinforced with a 304 stainless steel braid. The polyurethane jacket on the 919U hoses reduces the minimum and maximum temperature range (-40°F to +275°F). The silicone jacket on the 919J/919BJ PTFE hose reduces the lower operating temperature to -40°F.
