Female Gas Connector Hose End (with 9/16" UNF outlet) - Series B - 2024 on

GC1B - Female Gas Connector Hose End (with 9/16" UNF outlet) – Series B - March 2024 on

Component Part of the new High-Flow, Dry-Connect-Underwater, Gas Connector System.*

The GC1B female is a component part of the GC1B/30 gas connector hose.

The GC1B female fitting connects with the male end (GC2B) of the current AP Gas Connector System. (Series B, post March 2024) 

The GC1B female fitting connects to any hose with a standard (9/16" UNF) 2nd stage swivel connection.

*Launched in March 2024 the AP Gas Connector System (Series B) is a new and improved system that replaces the previous GCS (Series A).

PLEASE NOTE: The B Series connectors are NOT compatible with Series A connectors (including the Auto Air connector).

Introducing the new high performance AP Gas Connection System:

High-Flow, Dry-Connect-Underwater, Gas Connector System

• The new High-Flow system is rated to EN250 breathing performance down to 50m.

Higher flow is achieved by the mechanical opening of internal valves in both the male & female connectors.

• The new GCS is an Dry-Connect-Underwater system.
• The GCS can be connected underwater with or without pressure in the line.

Both male and female connections feature an automatic closure so that water cannot enter when disconnected and you do not push a slug of water into the hose on connection.

The dry system significantly reduces the probability of a free flow caused by water travelling to the second stage as a mist and then freezing the internals in cold water conditions. A dry environment also reduces internal corrosion increasing the longevity of the products.

• Versatile Quick-Connect System
  
  
  • Ergonomic design with easy-grip large collar and knurled rings on the female connector offers a simple push together/pull apart quick connect and disconnect.

• • The GCS male & female connectors are attached to the hose via a standard (9/16" UNF) 2nd stage thread connection and can therefore be fitted to other make hoses with 9/16” regulator fittings.

The GCS is a versatile system that can be used in multiple different configurations according to preference and the requirements of the dive, including the ability to plug in a multitude of off-board gas supplies to either the OCB, the ADV or to the rebreather manifold.

IMPORTANT NOTE: The GC3 FLOWSTOP MUST NOT be used in-line with the GCS system for open circuit use as the GC3 will significantly decrease breathing performance.
