Fit it Correctly

Our metal-valved tubes are fitted with double locking nuts to ensure a positive seating and prevent chafing around the union between the valve and the tube itself.

You should wind the inner ring away from the valve base by 1-2mm, then tighten the outer hexagon nut to clamp the rim.
