Single/Double

Description:

The RT Rod Seal is a T-shaped elastomeric sealing element supported by Back-up ring on both sides. It provides excellent sealing performance in both double and single acting applications. The RT is used in reciprocating hydraulic and pneumatic equipment and in high-pressure applications. It fits into the same simple groove as O-rings and eliminates rolling or spiraling, even under long stroke or dry rod conditions. It does not wedge into clearances or pinch off under motion or pressure and has good low-pressure sealing capabilities.

Features
  • High pressure
  • Geometrically locked assembly and wide base "T" geometry eliminate seal roll and spiral failure
  • Fits into standard O-ring grooves
  • Excellent temperature resistance when combined with FKM and PEEK
  • Ability to fit into existing grooves means that a retrofit can be made with no re-machining or major revisions to the existing hardware design.
  • With the possibility of rapid strokes, lateral shock loads, pressure surges, and uneven wear or stretching, T-seals still maintain zero extrusion gaps.
Applications
  • High pressure applications
  • MWD equipment
  • Molding machines
  • Aerospace equipment
  • Industrial hydraulics
  • Mobile equipment
  • Downhole tools
