The vented cap allows air to pass through, which is necessary on helms designed to equalize pressure in the hydraulic system during operation — using a non-vented cap on a helm that requires venting can cause pressure buildup that affects steering feel or leads to fluid weeping at other points in the system. Conversely, using a vented cap on a helm that requires a non-vented cap can allow fluid to weep out through the vent. Always confirm whether your helm requires a vented or non-vented cap by checking the original cap or your helm’s installation documentation before ordering.
