This duotight Tee Piece is suitable for EVABarrier Beer & Gas hosing in 4mm ID and 5mm ID ine or most tubing with 8mm outer diameter. 

It will not fit the 10mm OD EVABarrier line (with 6mm ID).

No clamps necessary!
We do recommend cutting your hosing straight, not on an angle, to ensure the line has a complete seal. To remove the fitting simply push in the collet and the hose can be removed. These push in fittings are suitable to be used up to 100 psi

These push in fittings have been engineered for maximised performance in both gas and liquid applications. Compared to other push in fittings on the market, duotight takes the double safety approach to all of the connections with two EPDM o-rings per hose port. No other push ins on the market have EPDM o-rings, let alone two! per push in connection.
