    Product Details

    GasIQ Maxex is a high-quality and high-capacity regulator (class 3 ISO 2503). Maxex is ideal for normal to high gas flows, e.g. in cutting and heating with high-performance cutting and welding systems such as N76/S80, etc.

    Maxex is a heavy-duty and robust, ergonomically designed regulator for accurate control of gas flow. It is available for most gas types. The regulator comes with a built-in preset safety valve to ensure the highest possible level of safety.

    Supplied with hose connections for 5.0 /6.3 mm or 6.3/8.0 mm internal diameter hose, and extra seals.

    Fuel Gas Regulators FAQs

    Regulators for acetylene and propane used with oxy-fuel welding, cutting and heating equipment: how to choose, fit and look after them.

    Can I use a propane regulator on an acetylene cylinder, or the other way round?icon-minus-redicon-plus-red

    No. Use a regulator that is designed and marked for the gas it is controlling. Acetylene needs a regulator built for acetylene, because an unsuitable regulator can give the wrong outlet pressure or contain materials that are not compatible with acetylene, and either can lead to an explosion.

    A regulator that is built for propane or another fuel gas should stay on that gas as well, so that its seals and internal parts are only ever exposed to the gas it was designed for. If you are unsure which gas a regulator is approved for, check the markings and the manufacturer's instructions, or ask our team before you connect it.

    What is the difference between an acetylene regulator and a propane regulator?icon-minus-redicon-plus-red

    Both are fuel gas regulators, but they are built for different gases, cylinder connections and pressure ranges. Acetylene is dissolved in a solvent inside the cylinder and must be used at low outlet pressure, while propane is stored as a liquid under its own vapour pressure and is usually run at somewhat higher outlet pressures. The materials used inside the regulator also differ.

    Fuel gas cylinder outlets and regulator nuts normally have left-hand threads, which helps stop them being fitted to oxygen. The cylinder connection and thread on the regulator must match your cylinder's valve outlet, so check the data on the regulator and the cylinder before you buy.

    What outlet pressure should I set on an acetylene regulator?icon-minus-redicon-plus-red

    HSE guidance says acetylene pressure must not exceed 0.62 bar (9 psi) unless the equipment has been specifically designed for a higher pressure, and that for most welding and cutting the working pressure should stay at or below that figure. Some acetylene regulators have a gauge or maximum setting that goes higher, but that does not mean the whole setup should be run there.

    The pressure and nozzle or tip size you actually need depend on the job and the torch maker's chart, so follow the torch and nozzle manufacturer's instructions and your own risk assessment rather than turning the adjusting screw up until the flame looks right.

    How do I fit a fuel gas regulator to the cylinder safely?icon-minus-redicon-plus-red

    Check the cylinder is secure and the valve outlet and regulator connection are clean and undamaged. Wipe the fittings with a clean dry lint-free cloth; never use oil, grease, jointing paste or tape on the connection, and keep your hands and tools free of oil and grease. Fit the regulator by hand first, then tighten with a spanner as the manufacturer instructs, remembering that fuel gas connections usually have a left-hand thread.

    Before opening the cylinder valve, wind the adjusting screw fully out (anti-clockwise) so that cylinder pressure does not strain the diaphragm. Always follow the instructions supplied with your regulator.
