The STAUFF Twin Clamp Body LNGF / LNUF (Light Series) provides reliable fastening for industrial pipes with identical (LNGF) or different (LNUF) diameters. Manufactured from Polypropylene (PP) or Polyamide (PA), these components support outside diameters from 6 to 22 mm. They are designed for pneumatics, machine tools and mechanical engineering applications. They ensure high structural stability and can be combined with the DPL Cover Plate. The available product codes include all catalogue families: LNGF-106/06-, LNGF-208/08-, LNGF-310/10-, LNGF-414/14-.
The STAUFF Twin Clamp Body LNGF / LNUF provides a proven technical solution for hydraulic and industrial applications. Integrated into the STAUFF Light Series, this component features a Twin Design that allows two pipes to be secured simultaneously, optimising space management and minimising installation footprint within complex systems.
The fastening system is divided into two main versions to meet specific installation requirements. The LNGF model is engineered for pipes with identical outside diameters, ensuring perfectly balanced clamping between the two parallel lines. By contrast, the LNUF variant is specifically designed for pipes with different diameters. This flexibility enables engineers to adapt the system to asymmetrical hydraulic circuits while maintaining the structural strength of the installation.
In terms of materials, the STAUFF Twin Clamp Body LNGF / LNUF is moulded from two high-quality polymers specifically selected for industrial applications. The first standard material is Polypropylene (identified by the code PP and its characteristic green colour), which offers excellent vibration damping and good basic mechanical resistance. The second polymer is Polyamide (code PA, black), which provides superior performance in more demanding mechanical environments.
The series covers a wide range of outside diameters within STAUFF Groups 1 to 4. Specifically, the clamp bodies can accommodate pipes, conduits and flexible hoses with diameters ranging from 6 mm up to a maximum of 22 mm (with equivalent imperial sizes from 1/8″ to 3/4″). From a geometric perspective, the overall clamp height (H) remains constant at 27 mm across all four groups, simplifying space standardisation in panels, while the overall width (L1) increases proportionally from 32 mm (Group 1) up to 70 mm (Group 4).
To increase the structural rigidity of the installation, the clamps can be combined with a Type DPL Cover Plate. These plates are supplied in zinc/nickel-plated carbon steel (material code W3). During assembly, to prevent deformation of the polymer and consequent loss of clamping performance, the technical guidelines strictly specify a maximum bolt tightening torque of 2.5 N-m (1.85 ft-lb).
Thanks to its excellent stabilising properties, the STAUFF Twin Clamp Body LNGF / LNUF is ideally suited to automation and fluid power systems. Its validated applications range from pneumatic systems and automotive technology to advanced instrumentation systems. It is also widely used in the machine tool industry, centralised lubrication systems and precision mechanical engineering projects.
