Tighten evenly to around 4.0 Nm (approx. 35 lbf·in), turning the screw steadily rather than in short bursts and checking the hose hasn't twisted or ridden up the fitting as the band closes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich size do I need?\u003c\/strong\u003e\u003cbr\u003eMeasure the hose once it is fitted over its connector, then choose the size whose range spans that diameter.
