Simple clip-on piston rings replace PTFE tape

Simple clip-on piston rings replace PTFE tape Where PTFE tape has to be specially made and fitted, the iglidur piston rings from igus can be simply clipped on the piston or shaft. This affordable option from igus is now available in a variety of  sizes and materials.

Whether in automotive applications, packaging and medical systems or in construction and agricultural machinery, the lubrication-free piston rings from igus have proved successful for years. The entire iglidur catalogue range covers 45 different materials, and if this is not enough it is even possible for users to  configure their own  piston rings. The most suitable materials here are iglidur J350 for high-temperature applications, the FDA-compliant iglidur A180 or the wear-resistant all-rounder iglidur J. These are also available now from stock in 24 special piston ring sizes.

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 the assembly of the entire unit can continue.

The iglidur 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. Their low cost and durability means they are a cheap alternative to PTFE tapes.
