VIEGA Viega 3243 fitting, pack of 10 (model 446666)

VIEGA Viega 3243 fitting, pack of 10 is a metal plumbing connector intended for use in sanitary and heating installations. Supplied in a set of ten identical fittings, it is designed to provide reliable threaded connections where G- or Rp-type threads are required. The component is offered in corrosion-resistant gunmetal or silicon bronze variants and features a polygon profile with roughened threads to ensure secure assembly and improved sealing performance in professional installations.

Advantages

The fitting’s construction from gunmetal or silicon bronze delivers good corrosion resistance and mechanical strength appropriate for potable water and heating circuits. A polygon head allows convenient tightening with standard tools, while the roughened thread improves grip for sealing materials and reduces the risk of loosening under thermal cycling. Supplied as a factory-packaged pack of ten, the set simplifies procurement for installers and helps ensure consistency across multiple connection points.

Suitable for

• Connection of pipes and components in sanitary systems
• Threaded joints in heating installations
• Replacement of worn or damaged threaded fittings during repairs
• Professional assembly of multiple identical connection points

Key specifications

• Material options: gunmetal or silicon bronze
• Thread types: G-thread (parallel) and Rp-thread (parallel internal threads compatible with Rp standard)
• Head profile: polygon for wrench engagement
• Thread finish: roughened thread for improved sealing interface
• Pack quantity: 10 identical fittings

How to use

Select the appropriate material variant and thread type that match the mating component. Prepare the pipe ends or mating threads by cleaning and removing debris, then apply the recommended sealing method for the system (for example, PTFE tape or approved thread sealant) following system design and local regulations. Hand-start the fitting onto the mating thread to avoid cross-threading, then tighten with a suitable wrench using the polygon head until the required torque or leak-tightness is achieved. Install fittings in accessible positions where periodic inspection and maintenance can be performed.

Usage recommendations

Use sealing materials compatible with potable water and heating system standards. Do not overtighten beyond the torque specified by installation guidelines to avoid thread or component damage. Store the pack in a dry place to prevent surface contamination prior to installation.
