Series 5000 quick-release couplings are suitable in situations where, for plant engineering or safety reasons, the connection or disconnection of tubing must be repeated several times.
These operations can be performed with no need to release the pressure and therefore a considerable amount of time can be saved.

- Series 5000 quick-release couplings with mini-profile DN 5 are compatible with couplings Rectus Series 21 – 90, Legris 21.
- Series 5000 quick-release couplings with European profile DN 7 are compatible with couplings Cejn Series 320.
