New ETFE flexible tube product – resistant to aggressive media and extremely flexible

We are pleased to present you with two new flexible tubes from our assortment. We now offer you our flexible ETFE tubes that are also available as a mesh-reinforced version.

As a result of the unique combination of ethylentetrafluorethylene (ETFE) in the inner layer and polyurethane (PU) in the outer layer, our flexible tubes have the media resistance of a fluoroplastic and are particularly resistant to acids and alkalis as well as the flexibility of an elastomer. The high pressure resistance is also outstanding that significantly outweighs other elastic tubes in comparison. As a result of the high elasticity, the flexible tubes have low bending radii so that the use of fittings that are necessary for a PFTE tube is dispensed with.

The flexible tubes are used in cable trays in printers and in the automotive industry as painting robots are continually moving and the tubes must withstand these rotations. Additional application areas include flexible tubes in robotics with a high reverse bending load, in plant engineering in confined spaces and in analysis systems.

1B+ - flexible tube connectors for mesh-reinforced tubes

The 1B+ tube connector is designed according to the 1+ principle and especially for mesh-reinforced tubes. As all of the Generation+ connectors, it consists of only two parts: the connector body and the pressure screw. The clamping ring is incorporated into the pressure screw. An extra clamping ring is not required. The thread and connecting sleeve are integrated inside in the connector body. The advantage: they cannot be damaged and are protected against external effects.

The pressure screw is used to secure against longitudinal forces that could pull down the flexible tube from the connecting sleeve and is designed to secure the flexible tube in place by intercepting any shear or torsional stresses. This allows for the application of up to 16 bar (Assembly instructions, Pressure Guides).

The connector is completely leak-proof when it is "hand-tight" and no tools are required. This significantly reduces assembly times. The pressure screw can also be tightened with a fork wrench so there is no gap between the connection and the connector body. The possibility of overtightening is excluded by the defined stop.

Corrugated flexible tube connector 1W+, ready for direct connection

There is a new member of our Generation+: we present the new 1W+ connector for corrugated flexible tubes – ready for direct connection.

For other conventional connections, corrugated flexible tubes normally have to be thermally smoothed in the connection area so that a flexible tube connector can be mounted. Users who are unable to do this themselves need to have the corrugated flexible tubes prefabricated in advance by a tube provider. This time-consuming and costly procedure is completely eliminated by the new 1W+ flexible tube connector from emtechnik.

The corrugated flexible tube can be pushed directly onto the slightly conical connecting sleeve inside the connector body. Then when the pressure screw is tightened, the corrugated flexible tube is fixed in place on the connecting sleeve. Like all the connectors of our Generation+, no clamping ring is needed because it is integrated into the pressure screw. That means the connector consists of only two parts, which makes handling considerably easier. The 1W+ connector provides a complete seal when it is "hand-tight" and is able to withstand pressures up to 10 bar (corrugated flexible tube up to 4 bar). No tools are required, which shortens assembly times significantly. The possibility of accidental overtightening is excluded by the defined stop. Different sizes and highly media-resistant plastics are available.

For Maximum Precision and Reliability: Diaphragm Pressure Gauge with Series 3D Manometer

Almost 50 years of experience is also evident in our new diaphragm pressure gauge with integrated manometer, which we developed especially for measuring pressure in neutral and aggressive media.

Precise measurement results

To protect the manometer from the corrosive affects of the medium, a diaphragm made of PTFE-TFM 1700 hermetically seals the manometer from the medium. The pressure is measured through a buffer fluid that transfers the pressure onto the measuring chamber of the manometer. The large surface of the diaphragm ensures high-precision measurement results. Since all parts in contact with the media are made of plastics with high media-resistance such as PP, PVDF and PTFE, our diaphragm pressure gauges are also especially well suited for aggressive media.

Durable and maintenance-free with a wide variety of uses

Other plus factors: Series 3D diaphragm pressure gauges are largely maintenance-free. They are durable and can also be installed in any installation position. To protect the manometer, but also to make your system more maintenance-friendly, we recommend installing a ball valve (emtechnik series 6L) between the pipeline and the diaphragm. This will ensure that any required maintenance can be performed with no problems, even with system pressure present. Series 3D diaphragm pressure gauges can be connected anywhere, as they are fitted with welding unions, female threads or male threads. Like all emtechnik threads, they are manufactured without seams and are absolutely leak-proof. Series 3D diaphragm pressure gauges are versatile and can be used wherever precise measurement results are essential. That includes the food industry, water treatment, refrigeration and air conditioning technology, the chemical industry, process analytical technology (PAT) and shipbuilding.

The advantages at glance:

  • The diaphragm, made of PTFE-TFM 1700, separates the manometer from the medium and protects against corrosion.
  • Large diaphragm surface ensures precise measurement results
  • All parts in contact with media made of PP, PVDF or PTFE for aggressive media
  • Durable and largely maintenance-free
