Pharmaline PTFE Hose

Pharmaline PTFE Hose Specification

Pharmaline is a unique, genuinely smoothbore PTFE-Lined hose product, based on a patented PTFE hose liner tube design.

Pharmaline is designed to overcome the very poor flexibility of currently available similar smoothbore products.

Pharmaline PTFE Hose

The only products which can match the flexibility of Pharmaline are convoluted PTFE lined hose products, sometimes misleadingly referred to as “smoothbore” or “smoothflex”, even when the bore is actually convoluted.

ALTERNATIVE PRODUCTS

Pharmalex (leaflet available) is a lower pressure, lighter duty alternative to Pharmaline. Pharmalex is the same as Pharmaline, but without any wire braid, and with a transparent silicone Rubber cover.

APPLICATIONS

Pharmaline is designed for use in high purity Pharmaceutical, Biotech, Chemical and Foodstuffs application areas where ease of cleaning the hose is required, both internal and external.

It is also very suitable for use in other general industrial applications, particularly those where hot fluids or gases are being passed, and if there is any risk of burns due to accidental touching of the hose – for example, hot oil or steam transfer applications.

ADVANTAGES OVER CONVENTIONAL HOSE DESIGNS

  • Pharmaline can be used to replace silicone rubber hoses, particularly where the much better chemical resistance and ease of cleaning of the PTFE hose liner is an advantage.
  • Unlike silicone rubber hoses, Pharmaline can be steam sterilised any number of times, without degradation of the hose liner.
  • Pharmaline can be 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 than its nearest rival product because the construction does not include any glass fibre filler layers. The PTFE weight per unit length, however is higher.

HOSE TYPES, DESIGNS & APPROVALS

Pharmaline GP has a PTFE hose liner tube, manufactured from PTFE material in accordance with FDA requirement 21 CFR 177.1550.

An antistatic option is also available, Pharmaline AS, using liner material in accordance with the FDA requirement 21 CFR 178.3297.

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 Labelling are available for the Pharmaline range of hose and hose assemblies.

PROPERTIES

  • Temperature Range: -60°c (-80°F) to +200°C (400°F).
  • Pressure vs Temperature – Pressure ratings are as listed up to 130°C (266°F), then reducing at 1% per 1°C (1.8°F) up to 200°C (400°F).
  • Vacuum – All sizes fully vacuum resistant up to 130°C.
