The secret to the superior sealing performance is not just the fact that a high quality EPDM O-Ring is used but there are two of them. The Double O-Ring means that there is literally have twice the sealing surface when compared with other push in fittings.
This makes the DuoTight fittings even more reliable and reduces the chance of leakages significantly.
The Double O-Ring System also means that a tube can be bend in a much tighter radius without causing leaking issues.
No clamps required.
EPDM Rubber:
EPDM – Ethylene Propylene Rubber which has excellent chemical resistance including being compatible with ozone, oils, wide variety of alkaline and acid compounds, water, alcohol, ketone and beverages.
