Solving the big problem from pressure leak, I recommend this seal!!
“TCN” is a rotary seal, it can sustain pressure up to 10 bar. It has a steel cover on the front and back. TCN is NBR and VITON material.

If you seeing the leakage problem from pressure. We recommend using these oil seal “TCV”& “TCN”. These two seals are suitable for pressure rotating shafts. For TCV look like a rubber edge, for pressure not over 3 bar. Meanwhile TCN, the pressure can go up to 10 bar. The different between NBR and FPM; NBR can sustain temperature from -25 to 120 °C. Rotating at 1200 rpm. FPM can sustain temperature from -20 to 250 °C. Rotating at 3500 rpm.
