knurled nut made by turning

The knurled shaft of the blind rivet nut provides a locking device to avoid the turning of the insert in the component. These knurled blind rivet nuts are used preferably in components with lower regidity (component material is less "hard" than the material of the blind rivet nut).They are available with different heads (dome, countersunk and small countersunk) and as open and closed end versions.

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 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 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 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.

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 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.
