very good thank you very much.
Good filter so far, fist stack is foam filled, second stack is their refillable mixed filter... Top fitting took some effort to seal properly, but once sorted (bit of fettling with sand paper to remove some manufacturing burrs), seems to have stayed tight. Pressure relief valve can be unwound to go off at lower pressures (set ours to 230bar), Spares seals and filter refills are included in the box. Brill price and speedy delivery.
