About NBR 70 Black X-Ring Seals
NBR 70 Black X-Ring Seals has good chemical strength to mineral oils and greases, Hydraulic oils H, HL, HLP, HFA, HFB, HFC to approx, and The stress of the medium reinforces the sealing function under severe working circumstances.
X-Rings
X-rings are specialized seals that offer significant advantages over traditional O-rings. Unlike O-rings, which feature a single sealing lip, x-rings have two sealing lips on each side, forming an “X” shape when viewed in cross-section. This unique design provides several key benefits, including improved sealing efficiency, reduced friction, and enhanced resistance to extrusion. X-rings are typically made from elastomers such as Nitrile (NBR), Viton (FKM), or Silicone (VMQ), allowing for compatibility with a wide range of fluids and temperatures.
NBR Quad Rings also known as NBR X-rings are intended to be used in rotary seal applications and in these cases they outperform a conventional O-Ring.
The design of the NBR X-rings with four lobes produces a more stable seal that avoids spiral winding. This makes a smaller groove length possible than the one needed for a normal O-ring. In a conventional O-ring groove, however, the NBR X-rings can also be used.
NBR Quad Rings are of the same size as the AS568A O-Ring sizes, also referred to as standard O-Ring sizes, and are available in a variety of materials.
NBR X-rings have good resistance to mineral oils, greases and water resistance of up to 100 ° C. NBR X-rings are not consistent with the majority of solvents, strong acids, elevated aromatic gases, and ozone/wetting.

Advantages of NBR 70 Black X-Ring Seals
- Enhanced Sealing Performance: The dual sealing lips of x-rings provide superior sealing capabilities, ensuring a more reliable and leak-free sealing solution compared to traditional O-rings.
- Reduced Friction and Wear: The X-shaped cross-section of x-rings distributes the contact force evenly, resulting in reduced friction and wear, thereby extending the seal’s lifespan and improving overall efficiency.
- Resistance to Extrusion: NBR 70 X-ring Seals are more resistant to extrusion under high-pressure conditions, making them ideal for demanding applications where conventional seals may fail.
- Back-Up Ring Integration: NBR X-rings can be combined with back-up rings to enhance their pressure resistance, enabling them to withstand extreme operating conditions without compromising their sealing efficiency.
Applications
X-rings find applications across various industries and sectors, including:
1、Automotive: NBR X-rings are commonly used in automotive engines, transmissions, and hydraulic systems to provide reliable sealing for fluids and gases.
2、Aerospace: X-ring seals are employed in critical aerospace applications, such as aircraft engines, landing gears, and hydraulic systems, where their exceptional sealing performance and durability are essential.
3、Industrial Machinery: NBR 70 X-rings are utilized in industrial machinery, including pumps, compressors, and hydraulic cylinders, to ensure leak-free operation and minimize downtime.
4、Oil and Gas: NBR 70 black X-ring seals play a crucial role in the oil and gas industry, providing effective sealing solutions for drilling equipment, pipelines, and valves in harsh environments.
Dynamic application:
—For sealing of reciprocating pistons, rods, plungers, etc.
—For sealing oscillating, rotating, or spiral movements on shafts, spindles, rotary transmission leadthroughs, etc.
Static application:
–As a radial-static seal, e.g. for bushings, covers, pipers, etc.
–As an axial-static seal, e.g. for flanges, plates, caps, etc.
–As an energizer element for elastomer-energized hydraulic seals where there is a risk of the O-ring twisting.
