This straight joiner is suitable for our EVABarrier Beer & Gas hosing in 4mm ID 5mm ID line or most lines with  8mm outer diameter. 

The thread on this fitting will suit:
MFL Ball Lock and Pin Lock Disconnects
Our MKIII and MK4 Regulators
Many other home brew fittings with MFL Thread

It will not fit the 10mm OD EVABarrier line (with 6mm ID) but we do sell these larger 10mm duotight fittings separately.

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.
