SMC KQ2 Series Pneumatic Fitting, 4mm Connection size, 6mm Connection size - KQ2R04-06A
This pneumatic fitting is a plug-in reducer designed to join different bore pneumatic lines in industrial automation systems. It provides a compact, push-in connection between smaller and larger tubing and is suited to Air line distribution where Durable materials and consistent operating conditions are required. The construction combines metallic and polymer components for service in control, pneumatic actuation and instrumentation environments.
Features and Benefits:
• Push-in connections allow fast tool-free assembly and disassembly
• Brass nickel plating resists corrosion for extended service life
• Stainless internal components reduce wear under cyclic use
• Polybutylene terephthalate body offers chemical resistance and light weight
• Rated to 10 bar for reliable performance under pressurised air
• Operates down to -5°C to maintain function in cool environments
• Brass nickel plating resists corrosion for extended service life
• Stainless internal components reduce wear under cyclic use
• Polybutylene terephthalate body offers chemical resistance and light weight
• Rated to 10 bar for reliable performance under pressurised air
• Operates down to -5°C to maintain function in cool environments
Applications
• Suitable for automation plant Air distribution and valve manifolds
• Ideal for conveyor pneumatic actuation connections
• Used with instrumentation lines requiring mixed bore transitions
• Can be used for factory electrical cabinet Air supply routing
• Suitable for retrofit of mechanical pneumatic assemblies
