Product Description

The GIST system, with its patented torsional operation, was developed by Leafield Marine to provide a compact and cost-effective system. Further savings in weight and fitting time have been achieved by integrating the hose and inlet valve designs, also manufactured by Leafield Marine.

This system is widely used in the leisure life-raft market due to its small size and is also used on the largest SOLAS life rafts due to its high flow and ruggedness. There are currently over 250,000 systems in use worldwide.

Due to the safety critical nature of this product and number of variants available, we suggest that you contact Leafield Marine directly to discuss your specific needs.

Please see Gas Inlet Valves and Hoses for use with this GIST system.
