X-ring 3,68x1,78 NBR 70

NBR X-rings are 4-lipped twin-action static seals with a cross-section shape that is almost square. The NBR oil-resistant X-rings achieve their sealing capabilities by being mounted and compressed inside an assembly axial or radial accommodation. The stress of the medium reinforces the sealing function under severe working circumstances.
NBR X-rings have good chemical strength to mineral oils and greases, Hydraulic oils H, HL, HLP, HFA, HFB, HFC to approx. 50 ° C and in water up to + 80 ° C
The NBR X-rings offer a good degree of stabilization as well for dynamic application, as the X-ring owing to its nearly square cross-section is not prone to swinging within the loop curling. NBR X-rings involve less radial pretensioning. Due to the reduced contact stresses, this results in less abrasion. A lubricant reservoir between the binding teeth can be developed because of the design of the NBR X-rings

FAQ

What materials are used in the X-ring?

The X-ring is made from NBR (Nitrile Butadiene Rubber) which provides excellent oil resistance.

What is the temperature range for the X-ring?

The X-ring can withstand temperatures up to approximately 50 °C for oils and up to +80 °C in water.

How does the installation of the X-ring affect its performance?

The X-ring should be mounted and compressed properly within the assembly to achieve optimal sealing capabilities.

Expert Advice: Ensure proper installation to minimize radial pretensioning and maximize the sealing efficiency of the X-ring.

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.
