The flexible tube for the connector 1D is first thermally widened and then pushed on the integrated connecting sleeve. The tube is secured in place by means of a knurled nut acting on the flexible tube. Thanks to the form-fit connection between the connecting sleeve and flexible tube, the connector has no dead volume.

The flexible tube is pushed onto the integrated connecting sleeve of the 1A flexible tube con-nector. By tightening the knurled nut, the clamping ring presses against the flexible tube and fixes it in place. The connecting sleeve for the flexible tube is nearly cylindrical. Its dimensions are calculated to prevent tube strain over 6%, even with poor tolerances. The tension produced by the low tube strain is sufficient by itself to guarantee a tight flexible tube connection up to 6 bar. The clamping ring and knurled nut secure the connection against longitudinal forces which could otherwise pull the flexible tube off the connecting sleeve. The clamping ring is designed to secure the flexible tube in place by intercepting any shear or tor-sional stresses. This allows for usage up to 10 bar*. Thanks to its elasticity, the clamping ring can be used several times in the same connector.

Our 3E inlay connector can be directly fastened to existing fittings with DIN 8063 male threads and is immediately ready for use with both flexible tubes and pipes. The inlay component of the 3E connector is manufactured as one piece with the connector integrated. This saves not only time and work, it helps to ensure that the connector is tight and thus safe to use.

The 2M connector was developed for thin pipes such as capillary tubes with an outside diameter from 0.7 to 6.35 mm. It consists of a sealing cone which is pushed into the matching inner cone of the connector and acts as a bushing for the pipe while performing a sealing function. An additional O-ring, which is protected from damage by a pressure disc, holds the pipe in place and prevents it from being pulled out accidentally.

The 1M micro connector was developed especially for medical, pharmaceutical and analytical technology. It provides ideal connection features for PFA, silicon or Tygon® flexible tubes. The micro connector consists of a connector body with integrated conical connecting sleeve, a knurled nut for fixing the flexible tube and a slotted pressure ring. The pressure ring can be omitted for PFA flexible tubes.

For the 2N pipe connector, the pipe is placed against the inner edge of the connector and a sealing ring seals off the connection. A cutting ring wedges into the flexible tube or pipe as far as the knurled nut is screwed onto the connector body, thereby fixing the connection in place. This creates a friction-locked and tight pipe connection that can be released at any time, that eliminates dead volume in the design concept and also has no effect on the flow. The inside diameter of the connector does not correspond to the inside diameter of the pipe.

In the luer lock adapter 3L, a luer lock thread to DIN EN 20594-1 or ISO 594 (male or female) is combined with our connection for flexible tube 1A, connection for pipe 2M, a Tri-Clamp connection or a G, NPT or UNF male thread. A flexible tube can thus be connected, e.g., to the most commonly used disposable laboratory filters.

The 1+ connector consists of just two parts, the connector body and the pressure screw. The clamping ring is incorporated into the pressure screw. The thread and connecting sleeve are integrated inside in the connector body. They cannot be damaged and are thus protected against external effects. Further advantages: 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 flexible tube is widened when it is pushed onto the integrated connecting sleeve of the 1B flexible tube connector. The tube is secured in place by means of a knurled nut acting on the flexible tube and the connecting sleeve. The connector permanently has a pressure stage of PN 10. Easily able to withstand a brief pressure peaks of up to 30 bar at T= 20°C.

The pipe or tube of the 2T pipe connector is inserted through the connector as required for bead tubes, immersion tubes, thermometers or sensors, etc. It consists of a sealing cone which is pushed into the matching inner cone of the connector and acts as a bushing for the pipe while performing a sealing function. An additional O-ring, which is protected from damage by a pressure disc, holds the pipe in place and prevents it from being pulled out accidentally.

The special design of the 1W+ makes it possible to slide the corrugated flexible tube directly onto the slightly conical connecting sleeve inside the connector body. Then when the pressure screw is threaded in, the corrugated flexible tube is fixed in place on the connecting sleeve. No extra clamping ring is necessary because it is integrated into the pressure screw. That means the connector consists of only two parts, which makes handling considerably easier.

This connector is specially designed for mesh-reinforced flexible 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 pipe or tube of the 2D pipe connector is inserted through the connector as required for bead tubes, immersion tubes, thermometers or sensors, etc. The pipe is placed against the inner edge of the connector and a sealing ring seals off the connection. A cutting ring wedges into the flexible tube or pipe as far as the knurled nut is screwed onto the connector body, thereby fixing the connection in place.

The flexible tube is pushed onto the connecting sleeve manually, causing the flexible tube to widen. To secure the connection against shear stresses, torsional stresses or longitudinal forces, you must use, e.g., a pipe clip to fasten the flexible tube in place on the connecting sleeve.

The firm flexible tube or plastic pipe is pushed onto the integrated connecting sleeve of the 1C connector. The sealing ring forms a tightness for the connection, while it is secured in place by a cutting ring. Due to the knurled nut, this also affects the flexible tube. The cutting ring wedges into the flexible tube or pipe as far as the knurled nut is screwed onto the connector body. A shear force is applied here that intensifies the contact pressure. This creates a friction-locked and tight connection that can be released at any time and minimises the dead volume.

The tube filter is a compact, economical and versatile filter available either as a particle filter or as a coalescence filter. It is easy to use and filter changes can be made quickly. It is fitted with an female thread and is also available with a shut-off or drain feature. In the COMPACT version, the tube filter is already equipped with integrated flexible tube connectors.
