iglidur® piston rings

Piston rings - an alternative to PTFE tapes  
Why complicate things when it can be done differently?

Replace elaborately stamped PTFE tapes with a single clip-on guide ring, such as in lifting elements, control valves and fittings. We offer iglidur® piston rings made of freely selectable materials for a wide range of applications.
 
Special properties

Easy to assemble

Low-priced

More wear-resistant than PTFE-bonds

Higher load capacity

Defined dimensions

different materials per ex. iglidur® J, J350…

When to use piston rings?

When piston rings with excellent wear properties are required

When simple assembly is of great importance

When high edge loads occur

When tailor-made solutions based on iglidur® materials are required


 
When not to use piston rings?

When the piston rings should seal simultaneously

When different diameters should be covered by one part
