Hep₂O Keyless isn’t a replacement for our original Hep₂O – now called Hep₂O Key, so you’re free to choose the fitting that works best for you.

Both carry the Wavin stamp of assured quality and performance, including our In4Sure technology for a secure joint every time.

Both offer full compatibility with each other, plus copper and our Tigris K5 press-fit system.

And both are guaranteed for 50 years.

Hep_vO waterless traps

Hep_vO is different to traditional water traps, using a soft silicone rubber membrane to create a seal, instead of ‘trapped’ water.

The space-saving, self-sealing valve opens under the water pressure of an appliance emptying, and closes to form a tight seal after the appliance has discharged under normal atmospheric conditions.

Fully compatible with Hep₂O Key and Keyless.
