ESAB DURA A-1.5 Acetylene Double Stage Regulator – 1.5 Bar

The ESAB DURA A-1.5 Acetylene Regulator is a professional double-stage gas pressure regulator designed for acetylene service in welding, cutting and heating applications. It is part of the ESAB DURA regulator range, developed for demanding industrial gas applications where controlled and stable gas delivery is important.

With a maximum inlet pressure of 40 bar, maximum outlet pressure of 1.5 bar and maximum flow of 250 L/min, the DURA A-1.5 provides controlled acetylene delivery for professional oxy-fuel equipment.

ESAB DURA A-1.5 Acetylene Regulator

The ESAB DURA A-1.5 Acetylene Regulator uses a two-stage pressure-reduction design. The first stage reduces the high cylinder pressure, while the second stage provides controlled delivery pressure to the connected equipment.

ESAB describes the DURA range as using an advanced two-stage design intended to maintain constant delivery pressure as cylinder pressure drops during use. This makes the regulator suitable for applications where consistent gas delivery is important.

Double Stage Pressure Regulation

The ESAB DURA A-1.5 is a double-stage regulator rather than a conventional single-stage regulator. The two-stage arrangement is designed to improve outlet-pressure stability over the operating life of the gas cylinder.

The maximum outlet pressure is 1.5 bar, while the maximum inlet pressure is 40 bar. The maximum specified gas flow is 250 L/min.

The actual working pressure and flow should always be selected according to the connected torch, nozzle, process and manufacturer’s operating instructions.

Heavy-Duty Acetylene Regulator

The DURA A-1.5 is intended for professional gas equipment environments. Published ESAB literature describes the DURA family with features including a forged body, stainless steel diaphragm, safety valve, inlet filter and fire-retardant polymer components.

The stainless steel diaphragm is designed to withstand the pressure associated with a full cylinder, while the regulator’s pressure-control system provides the required reduction for downstream oxy-fuel equipment.

250 L/min Maximum Flow

The ESAB DURA A-1.5 Acetylene Regulator has a maximum flow capacity of 250 L/min, equivalent to approximately 529.7 ft³/h.

This capacity makes the regulator suitable for professional acetylene applications where higher gas flow may be required for cutting and heating operations.

Users should not exceed the regulator’s specified pressure or flow limits. The appropriate operating settings depend on the connected torch, nozzle and specific application.

Double Gauge Configuration

The regulator incorporates two pressure gauges, allowing the operator to monitor pressure during operation.

The gauge arrangement provides useful information about the gas supply and regulated pressure. Operators should inspect gauges and connections before use and ensure that all equipment is compatible with acetylene service.

Acetylene-Specific Connections

The ESAB DURA A-1.5 uses:

• 5/8″ BSP L/H male inlet connection
• 3/8″ BSP L/H male outlet connection

The left-hand configuration is appropriate for the acetylene side of oxy-fuel equipment.

Always verify cylinder-valve and hose compatibility before installation. Never force a connection or modify a gas regulator to fit incompatible equipment.

Welding, Cutting & Heating Applications

The ESAB DURA A-1.5 Acetylene Regulator is suitable for professional applications including:

• Oxy-acetylene welding
• Gas cutting
• Metal heating
• Fabrication workshops
• Repair and maintenance
• Industrial cutting operations
• Pipe and metal heating
• General oxy-fuel applications

Its 1.5 bar maximum outlet pressure and 250 L/min flow rating make it particularly suited to acetylene-based welding, cutting and heating equipment.

Safety and Quality

ESAB states that its DURA regulators are designed with safety, performance and durability in mind. The published DURA literature identifies safety features including a self-resetting safety valve and inlet filtration, while also stating that the DURA products are BIS certified.

Because acetylene is a combustible fuel gas, the regulator must be used only with compatible acetylene equipment and according to applicable gas-safety procedures. Inspect hoses, fittings, valves and connections before operation and keep the equipment away from ignition sources except where the controlled welding or cutting process requires them.

Why Choose the ESAB DURA A-1.5?

The ESAB DURA A-1.5 Acetylene Regulator combines double-stage pressure regulation, double-gauge monitoring and heavy-duty construction for professional gas applications.

Its 40 bar maximum inlet pressure, 1.5 bar maximum outlet pressure and 250 L/min maximum flow provide the pressure-control characteristics required for many industrial welding, cutting and heating applications.

The regulator is identified by ESAB product code 4330180400.
