A low profile (shallow), heavy walled, convoluted PTFE hose, with external stainless steel vacuum spiral and 304 stainless steel braid as standard.

Excellent vacuum and pressure ratings, even at elevated temperatures

Choose when hygienic cleaning, transfer of heavy viscous products/liquids and adhesives are areas of particular concern.

Core Flow

Core-Flow's unique design offers you the same advantages of a traditional convoluted hose without the deep convolutions. This provides you with excellent drain ability and a hose which is easy to clean.

 

With a minimum wall thickness of 1.5mm for sizes 3/4" and above Core-Flow has unrivalled strength and is resistant to liner collapse.​ It is a leading product within the Pharmaceutical, chemical and food markets thanks to it's excellent vacuum resistance (-0.89 Bar) and full kink resistance.

To add to this Core-Flow is the leading PTFE convoluted hose when it comes to cleanability and offers the same flexibility as conventional PTFE hoses.

Braid Options

  • Stainless Braid - This hose is available with a 304L stainless braid as standard which is suitable for several applications. It also offers the highest temperatures (-70°C to +260°C) and working pressures alongside strong external protection.

  • Polypropylene Braid - A polypropylene braid is available as an alternative. This is ideal for hoses which are frequently handled thanks to its lightweight design. Polypropylene is more limited to lower temperature and working pressure environments. However, it has good chemical resistance against a wide range of chemicals.

  • PVDF Braid - Offering excellent compatibility with the majority of chemicals PVDF is the option to choose when the hose is subject to the harshest of environments. As with polypropylene it is only suitable in lower temperature and working pressure environments.

  • EPDM/SI Cover - This variant adds either a vulcanised EPDM rubber or silicone cover over the top of the 304 stainless braid creating abrasion resistance and an easy to clean cover. Excellent for hygienic applications.

Available Fittings

Core-Flow PTFE hose is compatible with a wide range of fittings available in mild or 316 stainless steel. The hose can be combined with hydraulic fittings such as BSP's NPT's JIC's etc. but is primarily used with flanges (ANSI/PN) and hygienic fittings such as Triclamps, SMS or RJT couplings. This is due to the unique design of the hose which allows the PTFE liner to be 'flared' through the fitting. PTFE lined fittings are generally manufactured from 304 SS as the PTFE liner offers superior protections versus aggressive chemicals.

Alternatives

Our Convo-Flow hose is a good alternative when the shallow convolutions of Core-Flow are not a specific requirement. The more traditional design of Convo-Flow can also go up to 6" in diameter and still remains flexible. 

Easy-Flow is the standard convoluted hose suitable for fittings with hydraulic tails. This can be self assembled with our ferrule range making it ideal for general purpose environments.
