RS PRO Brass, Steel Female Pneumatic Quick Connect Coupling, R 3/8 Male Threaded

Use this coupling from RS PRO for a fast and reliable way to set up your pneumatic system. It has a male quick-connect adaptor that lets you connect and disconnect tools and hoses from your air supply with one hand. This makes it a handy choice when you need to change tools quickly without putting your work down.
The coupling has a built-in shut-off valve to prevent air from leaking out when it's disconnected. It's made of nickel-plated brass for resistance to corrosion. It can also withstand temperatures between -20°C and +100°C, so it's a good option for use in harsh industrial environments.
You can use this versatile connector with CEJN 294, PCL Airflow and Rectus 19 series parts, making it easy to add additional parts to your current setup. The coupling is commonly used with garage or industrial airlines to connect tools such as nail guns and impact drivers.
