## Long description

Conex copper end cap 18 mm is a solid copper fitting designed to close and seal the open end of an 18 mm copper pipe. Intended for plumbing, heating and gas systems, this end cap provides a corrosion-resistant termination that can be used for permanent closures or temporary sealing during pressure testing and maintenance. The part is shaped to fit standard 18 mm copper tubing and offers a reliable mechanical and fluid-tight seal when properly installed.
Advantages
The copper construction delivers inherent corrosion resistance and good thermal conductivity, making the end cap suitable for use in hot and cold water, central heating and many non-aggressive gas applications. Its solid design provides mechanical durability and a consistent sealing surface. Because it matches standard pipe dimensions, installation is straightforward for qualified installers and enables secure closures without the need for complex adapters.
Suitable for
Sealing the end of 18 mm copper supply pipes in plumbing systems
Temporary closures during pressure testing and commissioning
Termination of branch lines in heating and radiator installations
Closing unused pipe runs before maintenance or renovation
Key specifications
Material: solid copper
Nominal pipe diameter: 18 mm
Application: pipe end sealing for plumbing, heating and gas installations
Compatibility: standard 18 mm copper tubing
Corrosion resistance: inherent to copper material
How to use
Ensure the pipe end is clean, free of burrs and accurately cut to provide a flush seating surface. Slide the copper end cap onto the pipe end and secure it according to the chosen joining method (soldering, brazing or approved mechanical connection) following applicable regulations and safety practices. For pressure testing, verify the joint integrity and test at the required system pressure. If soldering or brazing, use appropriate flux and heating technique to form a continuous, leak-free joint.
Usage recommendations
Use only in systems and environments compatible with copper material and follow local codes for gas or potable water installations. When used for gas applications, ensure all work is performed by a qualified technician and that joints are tested for leaks. For long-term reliability, avoid exposure to strongly acidic or alkaline chemicals that may accelerate corrosion.
