The Duotight In-Line regulator works with both gas and liquid. Easily adjust the flow with the yellow adjustment knob. 8 mm Duotight fittings at both inlet and outlet make this unit perfect for use with EVABarrier 8 mm OD tubing (D1717 or D1718).

Suitable for applications ranging from 0-150 psi. Since this unit does not have a built-in pressure gauge, it can be used in the full pressure range without ever needing to purchase or swap out the gauge. We recommend using an adjustable relief valve/spunding valve on your keg to set the pressure.

This regulator is perfect for lowering your mains water pressure for use with the Continuous Soda Carbonator Keg Lid.
