iglidur piston rings from igus can be clipped on the piston or bolt. The clip-on piston rings allow long-term use without external lubrication, maintenance or replacement of the polymer rings. Where PTFE tapes have to be punched in a complicated procedure and assembled in several steps, the piston rings from igus are simply clipped onto the piston rod or in the housing, they can be pushed to the desired position and already have the piston ring captively mounted and the assembly of the entire unit can continue. Errors in installation can then virtually be excluded.
The piston rings are suitable for linear and/or rotary and pivoting movements and are ideal not only for "clean" applications in medical and packaging technology, but also for "rugged" applications in construction or agricultural machines due to their freedom from lubrication, chemical resistance and corrosion resistance. By their low cost and durability, they are a cheap alternative to PTFE tapes.
