Stripper (figure 1) is an equipment that completes blowout prevention systems. It prevent the escape of oil or gas while running or pulling tubing under pressure.

It’s special rubber packer allows easy passage of tubing and tubing couplings without leakage. Stripper features a hydraulic actuator which allows the stripper rubber to be compressed quickly and safely without stopping operations. Stripper actuating pressure is 35÷70 bar.
Stripper can be operated using:
- CH6U-3000 psi control unit, or
- handpump.
