"Is this meant to be hissing....?"
We carry a huge range of adaptors, blanks, elbows, swivels, quick disconnects and switching blocks from a large selection of manufacturers. These range from Sub-Aqua products to Omniswivel to Swagelock and more.
We pride ourselves on our ability to offer a bespoke service where gas management is concerned.
This ranges from being able to advise you on the best way to configure your kit to hose management. We also offer custom gas management solutions for rebreathers and full face masks.
