These sealing elements are the evolved versions of RP/E-RC/I seals. LRP/E and LRC/I seals are composed of an O-Ring and a sliding element with a rectangular cross-section made of carbon filled PTFE. The O-Ring acts as a secondary static seal in the seat and ensures the necessary activating radial elastic pretension. The PTFE ring acts as a primary dynamic seal with low friction on the sliding surface. These seals can also be both single- and double-acting and are selfactivating with an increase in pressure.

• Low dynamic friction;
• No stick-slip at first detachment;
• No stick-slip;
• Compact size;
• Easy to assembe;
• Good resistance to wear.
