The X-RING sealing piston head (XRTP) with quadrilobed section, during dynamic stresses are not subject to rounding in the seat.
The X-rings have less wear than the O-rings because they require less radial pre-compression which results in less contact pressure.
A lubricant tank can be generated between the sealing lips.
There is an optimization of the sealing effect thanks to a better distribution of the pressure reported to the square section.
The X-rings eliminate any negative effects on the mold closing line, since it is located in the throat between the two lips.
