If you're looking to cut down on compressed air costs, then the Premium High-Flow Quick Coupling may be your answer. The aerodynamic tapered valve found inside will allow greater air tool efficiency (up to 40% higher flow) than the standard quick couplings. Featuring nickel-plated brass construction and colour-coding for easy identification, the push-to-connect design allows for ease of connection under pressure while the identical plug profile allows interchange between corresponding standard and High-Flow couplings. Instead of going up in size, try the Premium High-Flow Couplings to get the most out of your air tools. Please note, flow rates may vary by size and coupling series.
