Rotary Unions, Slip Rings and Combinations

Your benefits

Fine-tuned to precision

Wherever a multitude of media such as hydraulic oil, foam or water demand specific sealing solutions, GAT ensures maximum operational reliability.

Optimally adjusted sealing systems

We always pick the optimal sealing system from the broad range of products that have all been developed in-house. For example, we offer sealing systems that successfully protect equipment against abrasive rock dust, realizing unprecedented drilling times.

Tailored to your needs

Our engineers and technicians develop rotary unions and slip rings for any application – including combined solutions for the simultaneous transmission of media and electric power and signals.
