An adjustable hose connection relying on magnetic force to maintain seal is disclosed. The hose connection can be for connecting a vapor source, such as a nebulizer or hookah water pipe, to a delivery hose. The hose connection includes a male and female connector and a rubber seal between them. Both connectors have a magnetic element that attract to provide a seal and connection. The magnetic elements are preferably a permanent magnet in one of the connectors while the opposite magnetic element can be a ferromagnetic material such as steel. The strength of this connection can be varied by adjusting the magnetic gap between the male and female connectors with a threaded adjuster. The connection can thus be adjusted to find the optimal balance between seal strength and ease of disconnection in various environments.
