X-ring 50,52x1,78 NBR 70
NBR X-rings have a dual sealing feature in comparison with an O-ring and can be used in a broad range of static and dynamic sealing apps. In rotary seal apps, X-rings are also intended to outperform a conventional O-Ring. Our NBR X-rings are available in AS568 and metric dimensionsThe NBR X-rings or also known as NBR Quad rings offer optimized sealing effect owing to the higher pressure distribution over the nearly square cross-section.
These X-profile X-rings, have four contact points in dynamic applications, which guarantee a stronger seal than round-profile O-rings. To create a seal, they also need less compression, so they give longer service life. These NBR X-rings are produced of resilient, tear-resistant Buna-N rubber or NBR.
Typically NBR X-rings are used in water solutions, propane, butane, petroleum gas, mineral oil, grease, diesel fuel, mineral oils / grasses, diluted oils, alkali and salt.
NOT COMPATIBLE WITH.... Gasoline, benzene, trichlorethylene, ketone, acetone, acetone, ethylene, strong acids, glycol-based brake fluid..

X-ring 133,07x1,78 NBR 70Quad rings or X-rings of NBR have an benefit over conventional O-rings as the dividing lines are distant from the locking layer between the teeth. This eliminates the leakage issues often resulting from the irregular surface of a dividing line as discovered on an O-Ring. X rings provide a stronger, more homogeneous seal in these instances.
