Product Information

Full details

The Plasson 50mm End Plug is an essential mechanical compression fitting designed for professionals and DIY enthusiasts working with metric polyethylene (PE) water pipes. Its primary benefit is providing a highly reliable, leak-free seal that is fully compliant with UK Water Reg4 standards, ensuring safety for drinking water systems. However, users should note that it is specifically engineered for metric PE pipes, meaning it is not suitable for copper or PEX tubing of differing dimensions.

FAQs

Is this fitting suitable for hot water?

No, it is rated for 12.5 bar at 20 degrees Celsius. It is intended for cold water supply systems.

Can I reuse this fitting?

Yes, the mechanical compression design allows it to be disassembled and reused on another piece of PE pipe, provided the components are undamaged.

Do I need any specialized tools to install this?

No, it is designed for manual tightening. A wrench may be used for the final half-turn to ensure a secure fit.

Is it compatible with PVC pipe?

No, it is designed specifically for metric Polyethylene (PE) water pipes.

What is the pressure rating?

The plug is pressure rated up to 12.5 bar at 20 degrees Celsius.

Troubleshooting

Water leaking from the nut area

Ensure the nut is tightened properly. If it continues to leak, disassemble the fitting, check that the pipe was cut squarely, and inspect the O-ring for debris or damage.

Pipe will not insert into the fitting

Ensure the pipe end is not deformed or oval. Check that the internal grip ring is fully retracted and the pipe is clean and free of excessive burrs.

Pros and Cons

Pros

  • Certified for drinking water (UK Water Reg4)
  • Robust 12.5 bar pressure rating
  • Captive O-ring design prevents lost parts
  • High resistance to corrosion and UV damage
  • Fast and intuitive installation process

Cons

  • Designed only for metric PE pipes
  • Requires proper pipe end preparation for best seal
  • Not suitable for high-temperature plumbing systems

Setup, Compatibility & Care

To install, ensure the 50mm metric PE pipe is cut square and the end is deburred to prevent damage to the O-ring. Slide the nut and the gripping mechanism onto the pipe, push the pipe into the fitting body past the O-ring until it hits the pipe stop, and tighten the nut securely by hand. Use a wrench only if necessary to achieve the final turn. For care, avoid using petroleum-based lubricants on the O-ring, as these can degrade the rubber. Periodically check the fitting for tightness if the pipe is exposed to significant vibration or thermal cycling.
