Hose types, Designs & Approvals

Pharmalex GP has a PTFE hose liner tube, manufactured from PTFE material in accordance with FDA requirement 12 CFR177.1550

An anti-static PTFE option is also available, Pharmalex AS, using liner material in accordance with the FDA requirement 21 CFR178.3297

Advantages over Conventional Hose

  • Pharmalex can be used to replace silicone rubber hoses and tubing, particularly where the much better chemical resistance and ease of cleaning of the PTFE hose liner is an advantage.
  • Unlike silicone rubber lied hoses and tubing, Pharmalex can be steam sterilized any number of times, without degradation of the hose liner.
  • Pharmalex can used to replace conventional smoothbore PTFE lined hoses in applications where the much better flexibility of Pharmalex is an advantage.
  • Pharmalex can be used in low pressure, light duty applications in place of more expensive reinforced PTFE and Silicone hose designs.
