Product Information

Full details

The Hep2O Keyless Demountable Stopend is designed for professional plumbers and DIY enthusiasts needing a reliable, temporary or permanent termination for 22mm pipework in domestic water and heating systems. Its primary benefit is the combination of secure, leak-proof sealing with a completely tool-free demounting process, allowing for easy system adjustments. While highly versatile, users should note that the fitting is specific to 22mm sizing and requires proper pipe preparation to ensure the internal O-ring seal is not compromised.

FAQs

Can this be used on PEX pipe?

It is specifically designed for Hep2O polybutylene and copper piping; check the manufacturer's compatibility list for specific PEX brands.

Is this fitting reusable?

Yes, the demountable nature of this fitting allows it to be removed and reused on other sections of pipework.

Do I need to use a pipe insert with this?

Yes, when using polybutylene pipe, you must use a rigid pipe support insert to ensure a secure connection.

Can this be used for gas lines?

No, this product is strictly for domestic water distribution and central heating systems. Never use on gas lines.

What is the maximum temperature rating?

The fitting is designed to withstand standard domestic central heating temperatures; please refer to the Hep2O technical manual for specific thermal limits.

Troubleshooting

Fitting is difficult to push onto the pipe

Check that the pipe end is free of burrs and that the pipe has not been ovalized during cutting.

Water leakage around the fitting connection

Remove the fitting and inspect the internal O-ring for debris or damage; ensure the pipe surface is smooth and free of scratches.

Unable to demount the fitting by hand

Ensure the locking collar is fully rotated as per instructions; if debris has entered the mechanism, gently flush it with clean water.

Pros and Cons

Pros

  • Tool-free installation and removal
  • Provides physical feedback to verify pipe insertion
  • Suitable for both copper and Hep2O pipes
  • Highly durable construction with a 50-year guarantee
  • WRAS approved for potable water safety

Cons

  • Specific to 22mm diameter pipework only
  • Requires clean pipe ends to maintain a watertight seal
  • Higher initial cost compared to permanent solder fittings

Setup, Compatibility & Care

To install, ensure the pipe end is cut squarely and is completely free of burrs or sharp edges that could damage the internal seals. Push the pipe firmly into the fitting until you feel the resistance or hear the 'click' associated with the In4Sure technology. To demount, rotate the cap collar to release the internal grab ring and pull the pipe free. Always store the fitting in a clean environment to prevent dirt or grit from entering the internal mechanism, which could compromise the seal integrity during future use.
