Abstract

Arrangement to protect against leakage from sealing between a cylinder housing (3) and a piston rod (4). The arrangement comprises a holding ring (11), which is adapted to be fixated relative to the cylinder housing (3) so that it extends outside of the cylinder housing end (3) where the piston rod (4) enters the cylinder housing (3). It also comprises at least one packer (13), which is adapted to be arranged in a space between the holding ring (11) and the piston rod (4), and a press element (14), which is adapted to hold the packer (13) in place.
