VIEGA Viega 2612 gunmetal flange/disk, diameter 22 cm, pack of 5

VIEGA Viega 2612 gunmetal flange/disk, diameter 22 cm, pack of 5 is a set of five corrosion-resistant gunmetal flanges designed for plumbing and HVAC assemblies. Each flange features a 22 cm diameter and a robust construction that suits mechanical connections, sealing tasks and mounting applications where a durable metal flange is required. The product integrates a polygon-shaped HNBR sealing element and is compatible with press connections and Rp‑threaded fittings thanks to the built-in sealing and connection geometry.

Advantages

These gunmetal flanges offer corrosion resistance and dimensional stability for long-term use in wet and humid environments. The integrated HNBR polygon sealing element provides reliable sealing performance across standard service conditions. Compatibility with press connections and Rp threads simplifies installation and reduces the need for additional adapters. Supplied as a pack of five, the set supports multiple assemblies or spare-part provisioning for maintenance tasks.

Suitable for

• Plumbing pipework connections and branch installations
• HVAC mounting and flange-to-flange sealing tasks
• Repair and maintenance of metal fittings and flanged joints
• Applications requiring press connection and Rp-thread compatibility

Key specifications

• Material: gunmetal (corrosion-resistant copper alloy)
• Diameter: 22 cm
• Sealing element: HNBR, polygon-shaped
• Connection types: press connection and Rp-thread compatible
• Quantity: pack of 5 flanges/disks

How to use

Select the appropriate flange location on the pipe or fitting ensuring the 22 cm diameter matches the mating surface. Prepare the mating surfaces by cleaning off debris and ensuring proper alignment. Place the flange so the polygon HNBR sealing element contacts the mating surface, then secure using the suitable press tool or fasten to the Rp-threaded fitting following standard torque and installation practices. Verify the seal visually and perform a pressure or leak test according to applicable standards after installation.

Usage recommendations

Use flanges in environments within the material temperature and chemical compatibility limits of gunmetal and HNBR. Store components dry and protected from aggressive chemicals. For applications with unusually high temperatures, aggressive fluids or special regulatory requirements, consult material compatibility tables or the manufacturer’s technical documentation prior to installation.
