Quick Couplings

A quick coupling is a fast connector that joins and separates a hose or equipment from the line in one movement without tools. The female body and male plug lock together when pushed in.
It is used in compressor and compressed air lines, pneumatic hand tools and water hoses. It is supplied in brass, galvanized and stainless types, with threaded and hose-end bodies.
Main Applications
- Compressor outlets and air distribution lines
- Pneumatic hand tools
- Spray gun and blow gun connections
- Workshop air reels
- Water and washing hoses
- Test and measuring connections
