UNICHEM ST 6388 Ideal for chemical pumps and valves.

UNICHEM ST 6388 is a very pliable PTFE packing for sealing shafts and spindles. It is pre-impregnated with a special impregnation and provided with a thermally stable running-in lubricant. The packing is homogeneous, creep resistahnt and volumetrically stable. Due to the dense structure, softness and pliability of this packing a high degree of sealing effect is achieved with a minimum amount of gland pressure.

Used in sealing sets for TA-Luft certified applications.
