GC4/39 - 39" hose with the male end of the GCS and a standard (3/8" UNF) 1st stage end
The gas will only flow in one direction, from the male end towards the 3/8" UNF end. Standard length 39".
N.B. The male end will connect to the female connection of any AP150 (Auto Air) hose or the GCS hose - GC1/24.
IMPORTANT NOTE: The AP Gas Connector System (GCS) conforms to the EN250 regulator breathing standard down to 40m. Below this depth the breathing performance falls below this standard. If the GC3 FLOWSTOP is used in-line with the GCS the system conforms to EN250 down to 30m.
