Is the SJ aluminum swivel connector with BSP thread suitable for handling pressures up to 16 bar and temperatures from -40°C to +250°C?

Yes. The SJ aluminum swivel connector with BSP thread is suitable: it is manufactured from durable aluminum, rated for working pressures up to 16 bar and a temperature range of −40°C to +250°C, and is certified (PED 97/23/EC, TDT, TÜV, Apragaz). It is intended for slow and oscillating rotations and not for high bending moments (a heavy-duty double bearing version is available if needed).

Can the SJ aluminum swivel connector with BSP thread be used for slow oscillating rotations in chemical plants without transferring torsional forces to piping?

Yes. The SJ aluminum swivel connector with BSP thread is suitable for slow and oscillating rotations in chemical plants and is specifically designed so that no torsional forces are transferred to piping or other installation components. It is widely used in chemical and petrochemical industries, handles temperatures from −40°C to +250°C and working pressures up to 16 bar, and is certified to PED 97/23/EC, TDT, TÜV and Apragaz. Note: it is not intended for high bending moments — for heavy-duty or high bending use, request the double-bearing swivel joint.
