Greene, Tweed’s RSR™ rod or piston seal features a specially engineered elastomer profile that provides exceptional “dry rod” sealing under dynamic conditions. The RSR’s endless, trapezoidal wedge-shaped back-up ring has an exceptionally wide shear section to ensure excellent resistance to extrusion. In addition, the back-up ring’s shape generates a force vector under pressure,
thereby eliminating the extrusion gap. The result: very low leakage and fewer sealing problems.
The RSR seal excels in brake applications where the trapezoidal shape provides a natural pull back on the brake piston, therefore making piston design less complicated.
RSR™ seals are available in standard, zero, one and two back-up
gland sizes per MIL-G-5514/AS4716.
The part numbering system requires the use of the material designator tables found in the next column. For nonstandard designs contact GT engineering.
