The X-Ring (JT4) is a four lobed double acting seal. Thanks to its symmetrical shape, it is energised by the pressure which increases the quality of the sealing. The shape of the JT4 seal is similar to 4 tangent O-rings. The outside dimensions of the JT4 are defined in the same way as O-ring.
X-Rings are available on stock in Nitrile ( NBR) and Fluorocarbon (FKM). They can be produced on request with other materials such as EPDM or FFKM.
To improve the sliding effect, our NBR JT4 are produced with a specific coumpound including MOS2.
