X-ring cord

X-cord

With X-cord, a double-acting four-lip seal can be made with an X-shaped cross-section. The seal of X-cord obtains its sealing function by installation and compression in an axial or radial installation chamber. The sealing function is enhanced by the medium pressure.

Special features

• Optimal sealing function through improved pressure distribution

• Require low radial preload, resulting in lower friction

• No adverse influence by fleece, as the seal is positioned between the sealing lips

• Great stability in dynamic application, as the X-ring does not tend to roll in the groove

Applications

• The starting material for making X-rings

• The seal serves, for example, as radial and axial sealing of lids, bushings and flanges or as sealing of piston and piston rod, rotating shafts and covered screw movements

• Seals made of X-cord are mainly used for dynamic applications because they require less pretensioning than O-rings and thus produce less friction.

• Also often used for static applications and for reciprocating movements.
