Metal-rubber double pipe hanger Walraven BIS Cobra 0802124 for 1/2" pipes 20–24 mm

Metal-rubber double pipe hanger Walraven BIS Cobra 0802124 for 1/2" pipes 20–24 mm is a fastening solution that secures two parallel pipes with outer diameters between 20 and 24 mm. The product pairs a corrosion-resistant metal bracket with an elastomer lining to provide mechanical support while reducing vibration and noise transmission. Designed for plumbing, HVAC and industrial piping systems, the hanger maintains pipe alignment and protects pipe surfaces from abrasion and metal-to-metal contact.

Advantages

The combination of a durable metal clamp and a resilient rubber insert ensures long service life and dampening properties without compromising load-bearing capacity. The elastomer lining minimizes movement and vibration, helping to reduce noise and extend the life of connected pipes and fittings. Corrosion-resistant metal construction increases reliability in indoor technical spaces and sheltered outdoor installations, while the compact double-clamp design allows efficient routing of two pipes in parallel with consistent spacing.

Suitable for

• Plumbing systems for domestic and commercial buildings
• Heating, ventilation and air conditioning (HVAC) pipe runs
• Industrial process piping where vibration reduction is required
• Pipes requiring protection from abrasion and direct metal contact

Key specifications

• Designed for two pipes with outer diameter: 20–24 mm
• Compatible pipe size: 1/2" nominal pipe
• Construction: metal bracket with elastomer (rubber) lining
• Function: vibration and noise damping, surface protection, pipe alignment
• Mounting type: clamp-style hanger for fixed or semi-fixed supports

How to use

Position the double hanger around the two pipes so that the elastomer lining contacts the pipe surfaces. Align the hanger on the support structure at the required spacing and secure the metal bracket to the support using appropriate fasteners for the installation substrate. Ensure the rubber insert is seated correctly to provide full cushioning and check that the clamp provides the desired restraint without over-tightening, which can deform the lining or pipe. For runs of multiple hangers, space supports according to the pipe material and local installation standards.

Usage recommendations

Verify compatibility of the hanger with the pipe material and operating conditions including temperature and chemical exposure. Choose corrosion-resistant fixings where required and follow applicable building codes and installation guidelines for spacing and load distribution. Regular inspection is recommended in demanding environments to ensure lining integrity and clamp security.
