STAUFF Twin Clamp Body LBG / LBU
The STAUFF Twin Clamp Body LBG / LBU (Light Series) ensures precise clamping for pipes from 3.2 to 25.4 mm. Manufactured from Polypropylene (PP) or Polyamide (PA), it is ideal for pneumatics, lubrication and machine tools. The variants provide fastening for pipes with identical diameters (LBG) or different diameters (LBU). The available product codes (LBG base family) are: LBG-103.2/03.2, LBG-106/06, LBG-106.4/06.4, LBG-108/08, LBG-209.5/09.5, LBG-210/10, LBG-211.1/11.1, LBG-212/12, LBG-312.7/12.7, LBG-313.5/13.5, LBG-314/14, LBG-315/15, LBG-316/16, LBG-317.2/17.2, LBG-318/18, LBG-419/19, LBG-420/20, LBG-421.3/21.3, LBG-422/22, LBG-425/25, LBG-425.4/25.4.
The STAUFF Twin Clamp Body LBG / LBU is part of the Light Series and is designed to provide secure, stable and durable fastening of pipes, flexible hoses and industrial conduits. This family of fastening clamps represents a high-quality standard for mechanical engineering, offering effective solutions for vibration damping and noise reduction in fluid power systems.
The range is divided into two main types to meet specific system layout requirements. The LBG model (Clamp Body / Twin Design with identical diameters) is designed for the parallel clamping of two pipes with the same outside diameter. By contrast, the LBU variant (Clamp Body / Twin Design with different diameters) allows two pipes of different sizes to be accommodated within the same clamp body. This versatility is essential in complex circuits where space is limited and supply and return lines or instrumentation conduits have different diameters. Additional outside diameter combinations for the LBU variant are available from the manufacturer on request.
The clamps are manufactured from high-quality thermoplastic materials selected for their excellent mechanical properties and chemical resistance. The standard catalogue options include:
The clamp structure is designed with precise dimensions: the fastening hole diameters (Ø D3 and Ø D4) and overall dimensions (L1, L2, B, H, S) vary according to the size group, always ensuring perfectly coaxial clamping.
The STAUFF Twin Clamp Body LBG / LBU is suitable for a broad range of industrial applications. Its technical specifications make it an ideal component for the following sectors:
The clamp bodies cover an outside diameter range (Ø D1 / Ø D2) from 3.2 mm (1/8 inch) up to 25.4 mm (1 inch), divided into 4 STAUFF Groups (1 to 4). The structural dimensions scale according to the group: the overall length (L1) starts at 31 mm for Group 1 and reaches 70 mm for Group 4, while the centre distance (L2) ranges from 18 mm to 38 mm. Each component is identified by a clear order code that unambiguously defines the product specifications. The code (e.g. LBG-103.2/03.2-PP) consists of the series prefix, Group number, exact outside diameters and material code. This system allows engineers and purchasing managers to identify the exact component required for assembly.
