XL ROD SEAL
– A dynamic sealing element that ensures low friction, high speeds of operation and, thanks to the resistance chemistry of the material that exceeds those of all other elastomers, a high compatibility with almost all fluids.
– A standard low deformation O-Ring permanent as an energizing element on the static part
Features
• Low static and dynamic friction, even in absence of lubrication
• No “stick-slip” tendency
• Small footprint and simple execution of the headquarters
• Good resistance to extrusion
• High compatibility with almost all fluids (with the right choice of O-Ring material)
• High permissible speeds
• High temperature resistance
