Product Information

Full details

The Hep2O Keyless Pair Flexi Monobloc (KL125G-15) is an ideal solution for plumbers and DIY enthusiasts who require a reliable, flexible connection for 15mm monobloc taps. Its primary benefit is the patented In4sure joint recognition system, which provides tactile confirmation that a connection is secure, significantly reducing the risk of leaks during installation. While the keyless demounting feature offers excellent convenience, users should note that the 300mm length is fixed, necessitating careful planning of the route between the pipe and the faucet to ensure the flexi hose remains kink-free.

FAQs

Is this suitable for central heating systems?

Yes, the Hep2O system is fully compatible with domestic central heating and hot water distribution.

Do I need a special tool to disconnect it?

No, the keyless design allows you to disconnect the fitting by hand by pressing the release collet.

Can I use this with copper pipe?

Yes, this fitting is fully compatible with standard 15mm copper piping, provided the end is deburred.

What does In4sure mean?

In4sure is a technology that gives a tactile feeling, allowing the installer to 'feel' that the pipe is correctly and securely inserted.

Is it safe for drinking water?

Yes, the product is WRAS approved, meaning it meets strict standards for safety in potable water systems.

Troubleshooting

Pipe feels loose after insertion

Ensure the pipe is cut square and the end is deburred; remove and re-insert firmly to engage the internal grab ring.

Fitting will not demount

Ensure the collet is being pushed in evenly on all sides to release the internal teeth from the pipe.

Leaking connection

Check that the pipe is not scratched or scored at the point of entry, which could compromise the internal O-ring seal.

Pros and Cons

Pros

  • Tool-free installation and demounting
  • Instant peace of mind with In4sure connection technology
  • Highly flexible for navigating tight sink enclosures
  • WRAS approved for safe drinking water use
  • Robust build quality suitable for central heating systems

Cons

  • Fixed 300mm length may be too short for some configurations
  • Requires proper insertion force to trigger the In4sure mechanism
  • More expensive than rigid standard compression fittings

Setup, Compatibility & Care

To install, ensure the 15mm pipe is cut cleanly and deburred. Insert the pipe into the fitting until you feel the resistance and subsequent 'click' of the In4sure connection. To demount, simply push the collet inward and pull the pipe out. The fitting is compatible with 15mm copper pipe and standard Hep2O plastic piping. For care, avoid using abrasive cleaners on the outer braiding. Periodically check the joints for signs of moisture, though these fittings are designed for long-term, maintenance-free service. Ensure the hose is not stretched beyond its 300mm length or subjected to extreme twisting during installation.
