You can use this RS PRO quick-connect coupling to attach or detach tools to pneumatic lines with one hand. It features a plug system that automatically seals off upstream airflow when disconnecting, so it prevents leaks and loss of pressure. This coupling is compatible with Rectus Series 25 and 26 parts and a wide range of common pneumatic products, so you can use it in your existing set-up. It has a high flow rate of up to 1800 L/min, so it's suitable for heavy-duty tools like impact drivers and nail guns. The connector's brass and steel body and corrosion-resistant nickel plating make this a durable product that can handle harsh industrial settings. You'll find couplings like this in garages and workshops or in the construction industry.
