Hose Construction


Hose Liner

Seamless extruded PTFE tube. The extrusion, heat treatment and quality control programmes are designed to produce the best quality PTFE tube possible, ensuring minimum porosity and maximum flexibility.

Hose Braid:

Braided from AISI grade 304 stainless steel wire, bright hard drawn to a minimum 1700 N/mm2 tensile strength. The braiding process is closely controlled to ensure even tensions and the correct braid angle, to give minimum expansion/contraction under pressure.

Grades available, and applications

There are 3 standard grades available, with a Single SS wire braid (SB) or a Double wire braid (DB).

Single Braid is suitable for applications in general. Double Braid is required for higher pressures and increased kink resistance.

Grade SW, SB - Standard Wall, Single Braid (or DB, Double Braid)

For general purpose use, including high and low pressure steam, chemicals, paints, inks, adhesives, brake fluids, fuels, oils, detergents, refrigerants and foodstuffs.

PTFE lined hose is the optimum hose product wherever excellent chemical resistance, temperature resistance and/or internal “non-stick” cleanability are primary requirements of the application.

Grade HW, SB - Heavy Wall, Single Braid (or DB, Double Braid)

For heavy duty use, also for use with gases up to 100 Bar pressure, and for hot/cold cycling applications.

Grade MW, SB - Medium Wall, Single Braid, also called Hyperline SB (or DB, Double Braid)

The Hyperline name is applied to Aflex PTFE hose products which have an oversize bore, to enable assembly with standard Hydraulic End Fittings. In most cases, these sizes are the same as the conventional “dash” hose size range, as indicated in the specifications.
