Does the Nickel-Plated Brass Coupler, Type A3 require thread sealant or washers for a leak-free connection?

Nickel-Plated Brass Coupler, Type A3 requires additional sealing elements for a leak-free connection. Use Teflon tape or thread sealant on tapered threads, and aluminum or copper washers on cylindrical (straight) threads.

Can the Nickel-Plated Brass Coupler, Type A3 withstand continuous operation at its 60 bar working pressure in industrial pneumatic systems?

Yes. The Nickel-Plated Brass Coupler, Type A3 Format is designed for demanding industrial pneumatic use and specifies a working pressure capacity of up to 60 bar. Its nickel-plated brass construction provides strong resistance to wear, corrosion and mechanical stress, supporting continuous operation at that pressure. To ensure safe, leak-free continuous service at 60 bar, assemble the coupling correctly and use the recommended sealing elements: Teflon tape or thread sealant for tapered threads, and aluminum or copper washers for cylindrical threads. Proper installation, regular inspection and maintenance (checking seals, threads and general condition) are also essential to maintain reliable continuous performance.
