The sealing rings and rectangular rings used in rotary oil unions are exposed to extreme loads. The use of GAPI’s high-performance plastics—such as PAI GLon™ (based on Torlon® PAI) and PEEK GSpire™ (based on KetaSpire® PEEK)—has proven highly effective. These exceptional materials withstand consistently high pressures, rotational speeds, and temperatures.

Through continuous optimization, friction losses, leakage, and wear are reduced to an absolute minimum.
