Comparison with Silicone Rubber Hose
• Hygienic Clean Ability - much better, due to highly polished inner surface finish.
• Chemical Resistance - considerable improved, particularly to strong oxidizing acids and bases.
• Temperature & Pressure Ratings - much higher temperature and pressure capability.
• Steam Resistance - permanently resistant to steam sterilizing (unlike silicone hose, which has a limited life).
Comparison with Convoluted PTFE Hose
• Hygienic Clean Ability - vastly improved, due to smooth bore and hygienically polished inner surface.
• Flow Rates - more than 100% higher.
• Pressure Rates - more than 50% higher.
• Gas Permeation Resistance - more than 150% higher.
• Flex Life at Temperature and Pressure - more than 50 times the life, dependent upon conditions.
