Copper end cap VIEGA 22 mm (model 352813) for plumbing pipe termination

VIEGA copper end cap 22 mm is a plumbing fitting intended to close the open end of a 22 mm copper pipe. Manufactured from copper, this cap provides a corrosion-resistant seal suitable for potable water and heating systems. It is used to permanently or temporarily terminate piping runs, isolate sections for pressure testing, and protect pipe ends during installation or maintenance.

Advantages

The copper construction offers good corrosion resistance and thermal stability compared with some alternative materials. The 22 mm diameter matches standard copper pipe dimensions, allowing a secure, tight fit. Designed for compatibility with common soldering or pressure-connection methods, the end cap provides reliable sealing performance and long service life when installed correctly.

Suitable for

• Closing and terminating 22 mm copper potable water lines
• Sealing heating system pipe ends
• Pressure testing sections of plumbing installations
• Temporary capping during repair or renovation work

Key specifications

• Material: copper
• Connection size: 22 mm (for 22 mm copper pipe)
• Application: potable water and heating installations
• Function: end cap for pipe termination and temporary sealing

How to use

Prepare the pipe end by ensuring it is clean, free of burrs and properly measured to allow full insertion of the cap. Depending on the chosen joining method, follow standard procedures for soldering, brazing, or mechanical connection compatible with copper fittings. Fit the cap so it fully covers the pipe end and complete the joint according to applicable local codes and manufacturer best practices. Allow any soldered or brazed joints to cool and inspect for leaks before returning the system to service.

Usage recommendations

Use with 22 mm copper piping and select a joining method appropriate for potable water or heating systems. Ensure installations meet local plumbing codes and conduct pressure tests after fitting to verify a secure seal. For long-term installations, confirm compatibility of adjacent materials and avoid aggressive chemicals that could affect copper.
