These pneumatic quick-connect couplings from RS PRO have a 9 mm hose barb connection with male coupling threads for use with soft tubing in pressurised gas systems. They're interchangeable with Rectus Series 21 connectors and deliver fast, secure connections.

With their compact dimensions, these connectors allow you to precisely join tubes and hoses thanks to the high flow rate and low pressure drop they offer. A nitrile rubber seal means a tight fit that maintains pressure without the need for corrosive chemical sealants. Their nickel-plated brass construction makes them highly durable. You can use the couplers effectively at pressures of up to 35 bar and at temperatures ranging from -20°C to +100°C.

You'll find these pneumatic quick-connect couplings useful for a wide variety of pneumatic applications, including small air tools and dentistry equipment.
