Hose types, Designs & Approvals

Pharmaline 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, Pharmaline AS, using liner material in accordance with the FDA requirement 21 CFR178.3297

Both Pharmaline GP and Pharmaline AS have been tested and the PTFE liners comply with USP Class VI, including the Elution (Cytotoxicity) test.

Both include grade 304 SS wire braid and a platinum cured white silicone rubber cover (post-cured 4 hours at 200
°C in accordance with requirements for USP Class VI). The silicone rubber material is in accordance with FDA requirement CFR-177-2600.

ATEX - Attestations of Conformity and Labeling are available for the Pharmaline range of hose and hose assemblies.

Advantages over Conventional Hose

  • Pharmaline can be used to replace silicone rubber hoses, particularly where the much better chemical resistance and ease of cleaning of PTFE hose liner is an advantage.
  • Unlike silicone rubber lied hoses, Pharmaline can be steam sterilized any number of times, without degradation of the hose liner.
  • Pharmaline can used to replace conventional smoothbore PTFE lined hoses in applications where the much better flexibility of Pharmaline is an advantage.
  • Pharmaline is smaller in O/D and lighter in weight tan its nearest rival product because the construction does not include any glass fibre filler layers. The PTFE weight per unit length, however is higher.
