Is the Pressure Washer Spray Gun SG40 with 1/4" BSP GW Outlet rated for both hot and cold water up to +160°C and safe at continuous 350 bar working pressure?

Pressure Washer Spray Gun SG40 with 1/4" BSP GW Outlet — Yes. According to the description, the SG40 is engineered for both hot and cold water with an operating temperature tolerance up to +160°C. It is rated for continuous working pressure up to 350 bar (maximum capacity 400 bar) and maintains a flow rate of 30 l/min. The 1/4" BSP internal thread outlet provides secure connection, and the durable high-strength plastic housing plus ergonomic lever make it suitable and safe for intensive industrial cleaning at the specified temperatures and pressures.

Can the Pressure Washer Spray Gun SG40 with 1/4" BSP GW Outlet be used continuously at flow rates of 30 l/min while connected to systems operating near its 400 bar maximum pressure?

Yes — the Pressure Washer Spray Gun SG40 with 1/4" BSP GW Outlet can be used continuously at 30 l/min when connected to systems operating near its 400 bar maximum, with important caveats. The SG40 is engineered for a working pressure up to 350 bar and a maximum capacity of 400 bar while maintaining a 30 l/min flow, so its materials, lever mechanism and 1/4" BSP internal outlet are specified to handle those conditions. Continuous operation at or very near the 400 bar limit increases mechanical and thermal stress; to ensure safe, reliable continuous use you should: - Operate within manufacturer’s recommended working pressure (preferably ≤350 bar) for routine continuous service to maximize life and safety. - Ensure the connected system components (hoses, fittings, seals, pump) are rated for ≥400 bar and 30 l/min. - Verify temperature limits (SG40 rated to +160°C) are not exceeded during continuous hot-water operation. - Implement regular inspection and maintenance (check wear, leaks, seals) and replace parts showing degradation. - Use proper pressure relief or safety devices to prevent transient spikes above 400 bar. If you must run continuously at or very close to 400 bar, consult the manufacturer for duty-cycle guidance and any recommended upgrades or service intervals to mitigate accelerated wear and safety risks.
