Abstract
Sealing in an adapter for available sealing grooves, preferably for a reciprocating piston rod (1) of a cylinder (2) and for adapting the sealing to other types of sealing rings and comprising an adapter body (7) the outer dimensions of which substantially correspond to those of the available sealing groove (3) and having a radially inner sealing (8) providing a seal between the piston rod (1) and the adapter body (7) and a radially outer sealing (9) providing a seal between the adapter body (7) and the cylinder (2). Preferably the first mentioned sealing (8) is mounted at or adjacent the end of the adapter body (7), which is opposed the pressurized chamber (P) whereas the second sealing (9) is provided at or adjacent the end of the adapter body (7) facing the pressurized chamber (P). One and the same adaptor body may include one or several sealings of both kinds.
