Low Friction Hydraulic Rotary Seals Anti Extrusion Outside Sealing Small Groove
Rotary Seals Outside Sealing Small Groove
The RDA is a four-part rotary combination seal for piston. It consists a Teflon slide ring, an elastic o-ring and two L-shaped back-up rings excels in applications combining relatively high working pressures with low peripheral / sliding speeds. With the convave design on the slide ring, RDA increases the static contact area, preventing the seal from rotating along. It is specifically designed to isolate and separate hydraulic oils or other fluids at varying pressures, providing reliable double-acting sealing under pressure from both sides.
