PTFE Rings
PTFE Piston Rings and Guide Rings (Rider rings) for dry-running applications are currently a focal point of technical development.
They significantly reduce a machine’s operating costs and, in today’s increasingly environmentally aware society, make it easier for operators to fulfill stricter environmental legislation.

Guide Rings Material Selection
| Material Name | Compound % | Main Properties | Color |
| PTFE | / | Very low coefficient of friction and excellent chemical resistance.
FDA approved. | White |
| Glass Filled PTFE | Up to 40% | Improved ware resistance, compression strength, creep resistance, chemical resistance. Good performance in oxidising environment, good creep resistance. | White cream |
| Carbon Filled PTFE | Up to 35% | Improved electrical and termal conductivity, resistance to load, low coefficient of friction in dry, water, steam applications, chemical resistance. Superior ware resistance increase and low friction properties. | Black |
| Graphite Filled PTFE | Up to 25% | Improve wear resistance, decrease friction and increase sliding properties against soft metals- chemical inertness. Improve the temperature resistance in some way. | Black |
| Bronze Filled PTFE | Up to 60% | Improved compression strength, wear resistant, high thermal conductivity, resistance to abrasion. Reduced chemical resistance. | Dark Brown |
| Molybdenum disulphide(MoS2) Filled PTFE | up to 5% | Increased PTFE properties of hardness and wear resistance. Increased sliding properties and decrease friction. | Blue azure |
| PEEK Filled PTFE | Up to 20% | Increased thermal resistance, sliding properties, surface hardness. Superior properties on dynamic applications. | Light Brown |
| PEEK | / | Excellent mechanical properties including strength, rigidity, impact resistance, low wear rate and low coefficient of friction, retained over a wide range of service temperatures. | Light Brown |
| PEEK compound | / | Improves technical and chemical properties like deformation under load, wear resistance, thermal expansion and electrical conductivity. | / |
| PVDF | / | Resistant to UV radiation and offers high mechanical strength and abrasion resistance. | Beige |
| PCTFE | / | Better mechanical properties than other fluoropolymers, low permeability. | Translucent |
