Filling Manifold UNDERSEA 1232 - 10-way 414 bar

UNDERSEA Ltd has manufactured filling and gas distribution equipment for professional diving since 1970. The 1232 is a wall-mounted filling manifold bar machined from chrome-plated brass. It is rated to a maximum working pressure of 414 bar. Ten G1/4 BSP outlets span its 420mm length. This allows fill-room operators to connect a full rack of cylinders to one compressor line simultaneously. It is a standard fixture in BSAC clubs, commercial diving operations and technical diving centres across the UK and Europe.

Applications

Key features

Three advantages separate the 1232 from smaller UNDERSEA blocks: permanent wall mounting for a clean install, ten G1/4 BSP outlets for high-throughput filling, and a 414 bar chrome-brass body built to handle continuous daily use in humid compressor rooms.

1. 50-year UNDERSEA manufacturing heritage — parts and direct technical support available across the full product range; a reliability record established in BSAC clubs, commercial diving and technical centres since 1970.
2. 414 bar for air, nitrox and trimix — the G1/4 BSP thread standard covers recreational air fills through to helium-oxygen blends for technical diving without adaptor changes.
3. Ten simultaneous fill points, scalable with blank plugs — no repeated hose swaps for a full cylinder rack; blank plugs reduce active outlets from ten to any lower count as the installation evolves.
4. Chrome-plated brass in a compact 420 × 38 × 25mm wall profile — corrosion-resistant under continuous operational loads; the slim footprint keeps the fill-room floor plan clear and preserves operator movement.

Standards and product information

The UNDERSEA 1232 filling manifold is manufactured in the United Kingdom. As a pressure-bearing component in a breathing-gas distribution system, it falls within the scope of the Pressure Equipment Directive (PED 2014/68/EU) for EU member states. Installation and periodic inspection must be carried out by a competent person. Further guidance is available from the British Sub-Aqua Club (BSAC).
