This die cast multi-point adapters enable the connections of the cylinders fitted with self-closing valves to a high-pressure system through a standard 3/8 BSP Thread with unreduced pressure and a high flow rate. The salient features of these adapters are the multi-point locking mechanism which combined with a face seal ensures that the adapter will not leak even if it is loaded off axis. The adapters are fitted with a Non-Return Value to ensure that there is no flow of LPG Whilst cylinders are being disconnected. The quick disconnection arrangement couple with a safety interlock ensures that the device can only be disconnected after turning off the gas flow.
