Conex cap for copper pipe, 28 mm — Conex 5301 028000000

Conex cap for copper pipe, 28 mm — Conex 5301 028000000 is a copper end cap engineered to close off 28 mm copper pipework reliably during installation, testing or temporary shutdowns. Designed for compatibility with standard 28 mm copper tubing used in potable water, heating and general plumbing systems, this cap provides a solid mechanical closure that helps prevent leaks and contamination while work is being carried out.

Advantages

The copper construction offers good corrosion resistance, thermal compatibility with copper pipe and long service life in typical plumbing environments. The cap is shaped for a secure fit on 28 mm copper tubing and provides a straightforward, durable way to seal pipe ends without altering the existing pipework. Its material and form factor allow for effective use in potable water and heating installations where metal-to-metal contact is preferred.

Suitable for

• Temporary sealing of 28 mm copper water supply lines
• Isolating sections of heating circuits during maintenance
• Pressure testing and commissioning of plumbing systems
• Preventing debris entry during renovation or construction

Key specifications

• Material: copper
• Intended pipe diameter: 28 mm copper tubing
• Application environment: potable water, heating and general plumbing systems
• Function: end cap for temporary or semi-permanent closure of pipe ends

How to use

Ensure the pipe end is clean, free of burrs and cut squarely before fitting the cap. Slide the copper cap onto the 28 mm pipe end until it seats fully. Depending on installation requirements, secure the cap in place by soldering (brazing) or, if applicable, using an approved mechanical method specified for the system. After installation, carry out any required pressure or leak tests in line with local plumbing regulations and standard practice.

Usage recommendations

Use appropriate personal protective equipment during soldering or brazing. Verify compatibility with the system and local codes before choosing solder or mechanical fastening methods. For potable water installations follow relevant potable water installation guidelines to avoid contamination.
