EURO 7.6 Standard Pneumatic Quick Couplings – 320 Series
The 320 Pneumatic quick couplings from the POOLKE 320 Series are designed for industrial compressed-air systems that require high flow performance, easy handling and broad European-profile interchangeability. With a 7.6 mm nominal flow diameter and flow capacity up to 2100 L/min, the series provides efficient air delivery for pneumatic tools, production equipment and factory air networks.
The 320 Series features an unbaffled poppet design that helps improve airflow while keeping connection force low. One-hand operation allows fast tool changes and convenient maintenance, while nickel-plated brass/steel sockets and hardened zinc-plated steel plugs provide dependable durability for frequent industrial use. Optional double shut-off configurations are also available for applications requiring valve closure on both sides after disconnection. With multiple threaded and hose connection options, the 320 Pneumatic quick couplings offer a versatile solution for European-style pneumatic installations.
