This RS PRO quick-connect coupling lets you join pneumatic tools to air supply lines safely and easily. Its compact design means you can connect and disconnect it with one hand. The built-in plug system automatically seals off airflow, letting you remove components without the risk of leaks or pressure loss. This durable coupling is made of sturdy brass and steel, so it's hard-wearing and long-lasting. The nickel-plated finish means it's resistant to corrosion, so it's suitable for heavy industrial use. You can easily integrate the connector into your existing pneumatic system, as it's compatible with Rectus Series 25 and 26 parts, as well as other common products and fittings. Thanks to the coupling's high flow rate of 1800 L/min, it's ideal for use with impact drivers, nail guns and other powerful industrial tools.
