FluoroDiamond™ Piston Wear Ring

Piston wear rings are used to guide the piston in the cylinder tube and absorb transverse forces. FluoroDiamond™ refers to a special surface structure which is provided on the sliding surface only. The advantages are improvement of the lubrication properties, no stick-slip effect, higher load capacity and wear-resistance.

Piston Wear Rings are available in most PolyFluor™ and some PolyTel™ materials.
