Includes a filter, automatically reduces and maintains inlet water pressure at a constant pressure of 1 bar. This is used where microbore (4mm to 6mm) tube is installed, since these connections may leak at higher pressures. The alternative is to ease your garden tap partially on, to restrict water flow.

Do you need to fit this to a 5mm line (sometimes referred to as 4mm or 6mm) ?

We can supply 5mm end fittings or a mix of one 5mm and one 13mm fitting .. ie you could have a 13mm (1/2") inlet and a 5mm (1/4") outlet. Just phone or leave a note upon checkout.
