A billet separator with a 14.3 mm bore, listed for AN7 hose. AN7 is a less common size but it appears on brake and specialist plumbing where AN6 is a fraction too small, and finding support hardware to suit can be awkward. This separator handles two lines at that bore, holding them parallel and stopping them working against each other where the run passes close to bodywork or suspension components. Larger hose carries more mass, so unsupported spans swing harder and load the hose ends more; a couple of separators along the run makes a measurable difference. Confirm the outside diameter of your hose suits the 14.3 mm bore before ordering.
