Viega pipe insert fitting 20 x 22 mm, brass, polished (model 608125)

Viega pipe insert fitting 20 x 22 mm, brass, polished is a mechanical insert designed to join 20 x 22 mm pipes in water installations. Manufactured from polished brass, the fitting provides a metal-to-metal connection intended for plumbing systems in both residential and commercial environments. The part is engineered to create a durable coupling for standard pipe dimensions and to integrate with compatible Viega installation methods.

Advantages

The polished brass construction offers corrosion resistance and dimensional stability, supporting long service life in potable water and heating applications. The insert design ensures a secure mechanical joint without relying on adhesives or soldering, enabling faster assembly and straightforward replacement if needed. The compact form factor and standard sizing make it compatible with common pipe layouts and fittings used in modern plumbing systems.

Suitable for

• Joining 20 x 22 mm copper or compatible metal pipes in water supply systems
• Repairs and modifications in residential plumbing
• Commercial installations requiring durable metal couplings
• Connections where a polished brass appearance is desired for exposed areas

Key specifications

• Material: Polished brass
• Connection type: Mechanical insert fitting for metal-to-metal joint
• Pipe compatibility: 20 x 22 mm standard pipes
• Application: Cold and hot water installations, heating circuits where brass is suitable
• Finish: Polished surface for corrosion resistance and visual appearance

How to use

Prepare the pipe ends by ensuring they are clean, deburred and free of any contaminants. Slide the Viega insert fitting into the prepared pipe end until it seats fully to create the metal-to-metal contact. Depending on the overall system design, secure the joint according to the installation method appropriate for Viega fittings and the pipe material—this may involve crimping, pressing, or mechanical fastening as specified by the system requirements. Verify alignment and tightness before putting the system into service and follow local plumbing codes for pressure testing.

Usage recommendations

Use the fitting with pipes of the specified 20 x 22 mm dimension and compatible metal materials. Avoid using the insert with incompatible plastic pipes unless an approved transition fitting is applied. Follow manufacturer guidance and local regulations for installation techniques, maximum operating temperatures and pressures. Regular inspection during scheduled maintenance will help ensure long-term performance.
