ISO B6 Standard Pneumatic Quick Couplings – 310 Series
The 310 Pneumatic quick couplings from the POOLKE 310 Series are designed for efficient compressed-air connections in industrial equipment, pneumatic tools and automated production systems. With a nominal flow diameter of 5.5 mm and flow capacity up to 925 L/min, the series provides high airflow performance while helping reduce pressure loss in demanding pneumatic applications.
The 310 Series features one-hand operation and low connection force for fast, convenient coupling during daily use. Nickel-plated socket construction, a hardened zinc-plated steel plug and a durable locking mechanism provide reliable performance under frequent connection cycles. The 310 Pneumatic quick couplings also offer multiple threaded, hose barb and hose connection configurations, making them suitable for a wide range of compressed-air installations.
