DESIGN & PURPOSE

Hydraline FX is unlike any other PTFE hose product currently available.

The PTFE liner tube is smooth bore on the inside but convoluted on the outside, to combine the ease of assembly and high flow rates of a smooth bore hose with the flexibility and kink resistance of a convoluted hose in one product.

Hydraline FX is designed to be used in place of Smoothbore Hose when improved flexibility is required, and to replace Convoluted Hose when improved flow characteristics or easier assembly is required.

Hydraline FX is available in the following grades:

• Hydraline FX, TO          - Natural PTFE Tube Only, no braid.
• Hydraline FX, AS, TO   - Antistatic Black PTFE Tube Only, no braid.
• Hydraline FX, SS          - Natural PTFE Tube external 304 stainless steel braid
• Hydraline FX, AM         - Natural PTFE Tube , polyaramid fibre braid
• Hydraline FX, AS, SS   - Antistatic Black PTFE Tube, external 304 stainless steel braid
• Hydraline FX, AS, AM  - Antistatic Black PTFE Tube, polyaramid fibre braid. 

To special Order, Hydraline FX can be also be supplied with a Polypropylene or Kevlar Braid, To special order, Hydraline FX can also be supplied with a Polypropylene Braid, or with a Stainless Steel braid with an EPDM or Silicone Rubber Cover, or a PVC, Nylon or other Plastic Cover, printed if required.

**MWP = Maximum Working Pressures

PROPERTIES

Temperature Rating : The temperature rating is from -70° (-94°F) to +260°C (500°F), but the maximum working pressure (MWP) must be reduced by 1% for each 1°C above 130°C (1% for each 1.8°F above 266°F).

The maximum working temperature for the Polyaramid Fibre braided hose is +180°C (+365°F)

Pressure Resistance : The maximum working pressures are as listed, up to 130°C (266°F).  The design of conventional auto convoluted PTFE hose liner permits internal "pressing out" of the convolutions inside the braid over time and under temperature and pressure, leading to premature failures.  The narrow and highly compressed web sections of Hydraline FX are much more resistant to pressing out, hence a much longer service life under pressure can be achieved.

Tube Only grades can only be used at pressures up to 4 Bar (60 psi) up to 130°C (266°F) and are not fully vacuum resistant.

Full Vacuum Resistance : Stainless Steel braided Hydraline FX hose is vacuum resistant up to 130°C (266°F).

Reduced Diffusion Rates : The way the Hydraline FX tube liner is made, by web compression without fracture, surprisingly generates a much improved resistance to gas permeation, compared to any other type of smooth bore or convoluted PTFE hose.  Much lower diffusion rates can therefore be achieved.

Excellent Flow Rates : Due to the non turbulent flow through a smooth bore hose, Hydraline FX flow rates for a given pressure drop and actual bore size are 2 to 3 times higher than for a convoluted PTFE hose.  (This applies to the hose itself.  If end fittings are applied, however, which introduce a smaller bore at the ends, this multiple is reduced).

The 'whistling' noises created by the turbulent flow of gases or steam through convoluted hose are eliminated in Hydraline FX.

Excellent Internal Cleanability : Internal cleanliness and self-drainability are optimised by the smooth bore.  This eliminates 'pockets' of fluids trapped in internal convolutions.  'Bridging' with solid particles is also eliminated.

ASSEMBLY

Easier Assembly : Hydraline FX is very flexible, and is designed to replace conventional flexible tape wrapped convoluted or auto convoluted PTFE hoses in applications where faster, cleaner fluid flow or ease of assembly is paramount.  SS or MS ferrules and crimp diameters can be supplied to suit any conventional hydraulic hose tail end fittings.

Problems associated with assembling fittings to convoluted hoses, such as leakages, the need for special or sleeved spigots, the need to de-convolute disappear - Hydraline FX is literally as easy to assemble as any smooth bore hose.

APPLICATIONS

• Automotive and Motor Sport - replacing conventional PTFE hoses in ESP systems, fuel systems, braking systems and oil lines.
• Refrigeration - refrigerant feed lines to freezer plates, where the high resistance to permeation, together with the flexibility and chemical resistance are primary advantages.
• Steam and Gas Lines - where the smooth bore ensures non turbulent gas flow, leading to noise free operation at higher flow rates and longer service life.
• Industrial applications in general where the ease of assembly to end fittings together with the higher flow rates, chemical and temperature resistance and resistance to permeation make Hydraline FX the optimum choice.
• Not suitable for use in applications requiring PTFE lined and Flared End Fittings - for such applications only Bioflex is suitable.

Hydraline FX - The PTFE hose which surpasses all others for ease of assembly and technical advantages.
