The Parker R5 profile is a bi-directional piston seal for use in medium to heavy duty hydraulic actuators. The R5 profile is a two piece design comprised of a standard size rubber square ring energizing a rectangular shaped PTFE cap. The R5 profile offers excellent stability, long wear, low friction and extrusion protection. The seal is commonly used in applications such as agriculture hydraulics, mobile hydraulics, machine tools, and hydraulic presses. Parker's R5 profile is designed to retrofit non-Parker seals of similar design and is an updated version of the Parker R5100 piston seal. Options: Split Rings: To aid in installation, the PTFE ring can be supplied in one of the following split configurations: Step cut; Butt cut, Bevel cut.
