The BECA 500 profile is a double acting composite piston seal composed of a filled PTFE friction ring and a pre-tightened rubber O'Ring. It follows the bore diameters, in line with the standards MIL-G-5514F and AS4716.
Advantages
Optimal sealing in static and dynamic applications
Low friction coefficient; no stick-slip effect
Excellent abrasion and extrusion resistance
Wide temperature range and excellent chemical resistance, depending on the material selected for the O'Ring
