Aimed as a substitute for metal, nylon’s light weight and corrosion and abrasion resistance have made it an attractive design choice.

NYLOTUBE® is offered in two formulations, nylon-11 and nylon-12. While both types exhibit similar physical properties and performance, nylon-11 is available in a food grade version made of FDA-approved materials (semi-rigid style, natural color). Nylon-12 is typically used in various industrial applications and is somewhat less expensive than nylon-11.

Nylon’s elastic memory is exceptional and can withstand repeated flexing over a long period of time without fatigue or fracture. This makes it a popular choice for retractable coils. NYLOTUBE also offers high-impact resistance, even at subfreezing temperatures, and low moisture absorption to minimize dimensional instability.

The industry-standard convoluted flexible PTFE hose.

Corroflon was launched in 1978 and, since then has been continually updated and improved.  Now it is the industry-standard convoluted flexible PTFE hose for major chemical, pharmaceutical and food companies worldwide.

The key to Corroflons success lies in its design and build quality, which guarantees a long, safe and reliable service life.  Corroflon′s design differs from every other convoluted PTFE hose on the market, which results in distinctive and measurable performance and safety advantages.

Firstly, Corroflon will give better cleanability and drainability than any other convoluted PTFE hose on the market.  This is because Corroflon is designed and manufactured in such a way that the angle of the convolutions is extremely shallow -80° to 120°, compared with only 45° to 65° in other convoluted hose designs.

Secondly, Corroflon is the only PTFE lined convoluted hose on the market to be fully kink and vacuum resistant at high temperatures. This is because Corroflon′s design incorporates a thick section external helical reinforcement wire, which gives the radial support necessary to ensure maximum strength, while maintaining optimum flexibility and cleanability.  The helix wire is welded directly to the end fittings at each end, ensuring security of attachment and electrical continuity.

And thirdly, Aflex is the only PTFE hose manufacturer to guarantee a minimum PTFE liner thickness of 1.5mm for hose sizes 1′′ and above, which ensures sufficient strength to prevent the tube from being internally pressurised from a sine wave shape into an extended square wave shape, which would lead to porosity and eventually premature failure of the tube.  This thick wall liner also minimizes permeation and is extended through the end fittings to give an uninterrupted clean flow or fluid through the fitting.

Pharmalex is a very flexible, patented smoothbore PTFE lined hose product with a clear silicone rubber cover. It is designed to replace conventional all-silicone rubber hoses in applications where the inner silicone rubber liner may be subject to chemical reaction with fluids passing through, which may either contaminate the fluid, or degrade the rubber liner.

Applications:

Generally, Pharmalex is designed for light duty applications, with low internal fluid or gas pressures.

Pharmalex 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.

ALTERNATIVE PRODUCTS

Pharmaline (leaflet available) is a higher pressure capable, heavier duty alternative to Pharmalex. Pharmaline includes an SS wire braid between the tube and a white silicone rubber cover.

HOSE TYPES, DESIGNS & APPROVALS

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

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

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

Both include a Platinum Cured clear (transparent) 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.

Alternative colours of the silicone rubber cover are also available, to special order.

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. 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.

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.

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.

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.

Alternative colours of the silicone rubber cover are also available, to special order. Clear, transparent silicone is one alternative, which is USP VI approved and permits inspection of the inner braid condition.

Pharmaline GP and AS are available in 1/4′′, 3/8′′, 1/2′′, 3/4′′ and 1′′ bore sizes.
