A regulator with a long rubber hose and metal connectors. This is a Reyson regulator. The last overhaul was in 2018, so please have it overhauled before use. It has a swivel hose. I actually use a similar regulator and it feels very comfortable. Please note that the last photo shows the condition when 200 bar pressure was applied. - Able to breathe on land - Purge button operation - No free flow Confirmation date: December 16, 2025 This does not guarantee operation, but confirms what was observed at the time. This is a used item, so please understand that it is sold as-is (no returns, no refunds, no exchanges). Thank you for viewing.
