The D18CTF is designed with a quick connector for use with low pressure pumps. The spring-loaded valve with a passband of 4.5 mm is suitable for filling large volumes with viscous materials or mineral grout, making the D18CTF very versatile.

The special feature of the D18CTF lies in the changed position of the valve. In comparison to the D18CF, the valve has been moved 20 mm further away from the coupling, making it suitable for use at a 45° angle. This ensures the valve stays intact after cutting.

The enlarged eighth plate (used with a setting mounting tool) helps to ensure that the packer is not seated too far into the wall, so the clutch is always reachable.

Our single use injectors negate the need for cleaning or removal like traditional steel packers. After application, the packer remains in the wall and can be cut off flush to the wall. The free-running ball valve ensures a secure closure, provided a backpressure of at least 3 bars is present. In low-pressure applications (less than 3 bars), the ball-closure may not close in this case, caps are available (Kappe/C).

Our products can be used in construction projects great and small. Used correctly they are the best injectors available on the market and are the first choice of construction experts. We do not make any claims as to the maximum back-pressure our products can withstand. You, as construction professionals can judge the conditions present in your own projects and use our products accordingly.

To avoid damage of the quick-coupling clutch and to set the Packer correctly in the borehole, it is necessary to use the setting tool (ESH/C).
