WhiffAway Waterless Urinal - Hygiene Seal / Valve

A component of the WhiffAway Waterless Urinal – the patented ‘WhiffAway Waterless Urinal – Hygiene Seal / Valve’ prevents any aromas in the pipework. The seal is constructed with “memory” silicon that opens up when liquid hits it from the top then effectively seals up when liquid is no longer flowing.
