The BARTSHARP Airbrush Quick Release Coupler has been tried and tested by thousands of our airbrush customers and is a relied upon as an essential airbrush accessory. The quick release disconnect ensures a quick and smooth connection and disconnect between the airbrush and airbrush hose (I/8BSP fittings (9.35mm diameter approx)). Airflow, from the compressor, is automatically shut off by the connector when the airbrush fitting is released. Each Quick Connect Coupler comes with a fitting which screws onto your airbrush inlet (1/8BSP). To eject the airbrush fitting simply pull back on the main body of the QRC. This process allows for quick removal of an airbrush for cleaning or colour change or for another airbrush to be attached to the QRC (further airbrush connector fittings may be required). 1/8BSP is one of the most common types of thread/pitch used within airbrushing. The airbrush connector also freely swivels within the main body of the coupler to prevent airbrush air hose kinks. The airbrush connector has a small rubber o ring which provides an airtight seal when screwed onto an airbrush., Weight: 0.0551155655 Pounds, Manufacturer: BARTSHARP Airbrush
