## Long description

VIEGA Zaślepka 18 is an 18 mm pipe end cap designed to close or seal the end of a plumbing line. Intended for domestic and light commercial applications, this cap combines a brass-plastic construction that provides a durable sealing solution for temporary or permanent closure of pipe sections. It is suitable for use during maintenance, pressure testing and when isolating unused branches in heating, water supply or drainage installations.
Advantages
The brass/plastic construction ensures corrosion resistance where metal contact is required and reduces the risk of damage during handling. The 18 mm bore size matches standard small-diameter plumbing runs, enabling a secure fit and reliable sealing. Its compact design allows installation in confined spaces and offers a straightforward method to isolate sections of pipework without extensive modifications.
Suitable for
 Temporarily sealing open pipe ends during maintenance or installation work
 Pressure testing sections of a plumbing system
 Isolating unused branches in heating and water supply networks
 Protecting pipe ends during storage or transport
Key specifications
 Nominal pipe diameter: 18 mm
 Material: brass combined with plastic sealing components
 Application area: heating, potable water and drainage systems in residential and light commercial buildings
 Function: end cap for closing/sealing pipe ends for temporary or permanent use
How to use
Clean the pipe end to remove debris, scale or residual solder before fitting. Ensure the internal diameter and pipe condition match the cap requirements. Push or fit the cap onto the prepared pipe end according to the manufacturer's recommended method for the brass/plastic cap type; if required, secure using the appropriate fastening or sealing technique specified for the installation (for example, mechanical press-fit, thread or adhesive as applicable). After installation, perform a pressure check where necessary to confirm the integrity of the seal.
Usage recommendations
Verify compatibility with the system medium (potable water, heating fluids or drainage) and observe local plumbing regulations. Use the cap only on pipes with the matching 18 mm nominal diameter and follow standard safety and installation practices, including pressure testing and system purging after installation.
