Single-use packer intended for use with high pressure in both pre- and post-grouting applications. A compressible mechanical packer used for sealing boreholes at the tunnel face, in forepoling, excavation pits, and similar applications. The packer (rubber element) expands when the locking rings are pressed against the packer’s end pieces. The packer should not be exposed to direct sunlight or temperatures above 50°C. The recommended torque to be applied to the tightening nut is 80–100 Nm to ensure proper anchoring in the borehole and to prevent grout leakage between the borehole wall and the packer.
