Description

RT provides optimum leakage control and good resistance to extrusion. The seal is a double-acting O-Ring energized piston seal for dynamic applications. Installed in grooves to ISO 7425, it has excellent friction characteristics with no stick-slip, minimal breakout force and high wear resistance.

The edge angle of RT permits an additional degree of 
freedom and enables a slight tilting movement of the seal. The 
maximum compression is thus always shifted towards the area 
of the seal edge directly exposed to the pressure. 
On the low-pressure edge of the seal, RT exhibits only 
zones with neutral strains without compressive or shearing 
loads, thus effectively reducing the danger of gap extrusion. 
The resulting benefits are as follows below.

Advantages

- Very good static sealing performance 
- Increased clearance possible (approximately +50%), 
depending on the operating conditions 
- Low friction, no stick-slip effect 
- Simple groove design 
- Fits standard ISO 7425-2 seal housing 
- Adaptable to the operating conditions due to a wide range of materials  
- Suitable for environmentally friendly hydraulic fluids 
- Available for all rod diameters up to 2,600 mm

The main benefits of the patented seal are provided by the innovative functional principle of the trapezoidal profile cross section.

The sides of the seal profile tapers towards the seal surface.

The profile can thus retain the robust and compact form typical of piston seals without losing any of the flexibility 
required to achieve a pressure-related maximum compression.
