Question 1

1. “How do I know the fitting is actually locked and secure?”

Accepted Answer

Hep₂O Keyless has an audible and tactile ‘click’ when the pipe is fully inserted. You’ll feel it hit home and stay put. The internal grab-ring design gives a consistent, repeatable lock every time , so there’s no second‑guessing or partial engagement.

Question 2

2. “Can it accidentally unlock or pull apart under pressure?”

Accepted Answer

No. Once the pipe is inserted, the Keyless mechanism forms a permanent mechanical grip that holds under system pressure, thermal expansion, and vibration. The fitting is tested well beyond typical operating pressures, giving installers full confidence on both hot and cold runs.

Question 3

3. “If it’s ‘keyless’, how do I demount it when I need to?”

Accepted Answer

You simply push the pipe up into the keyless connection and release. This will unlock the device and allow the pipe to be removed.

Question 4

4. “Does the new design fit with the Hep₂O pipe and fittings I already carry?”

Accepted Answer

Yes. Keyless is fully compatible with existing Hep₂O pipe, fittings and accessories. You don’t need to change your materials or working habits—just benefit from a quicker, cleaner installation.

Question 5

5. “Will it hold up over time, especially on heating?”

Accepted Answer

Absolutely. The Keyless mechanism is designed for long‑term reliability , maintaining joint integrity through thousands of heating cycles. The grip and seal performance match the proven Hep₂O heritage that installers already trust.
