Customized Quard Ring NBR 90 Shore X Ring Seal with OEM Accepted by ORK for Mechanical Seal Burgmann
X-Rings, also known as Quad-Ring Seals, can be used in a wide variety of static and dynamic
sealing applications. In reciprocating applications, the X-Ring four-lobed design prevents spiral
failure and in rotary applications, it prevents the seal from bunching and failing. We supply both
Quad-Ring branded seals manufactured by Minnesota Rubber and Plastics, Quadion LLC as well
as similar seals described in various ways like X-Rings and Q-Rings.
The four-lobed design provides two sealing surfaces in comparison to a standard O-ring. The
double-seal action requires less force to maintain an effective seal. This reduction in force means
less friction and improved seal life.
X-Ring parting lines are between the lobes, away from the sealing surface, thus eliminating the
problems of leakage often resulting from a parting line's irregular surface as found on an O-Ring.
The unique design of the X-Ring allows it to be used in narrower grooves and also in standard
width O-ring grooves.
NBR Rubber :
Nitrile rubber (NBR, Buna-N) provides excellent resistance to petroleum oils as well as mineral and vegetable oil.
Nitrile rubber also offers strong resistance to heat aging - often a key advantage over natural rubber.
Nitrile rubber performs well in carburetor and fuel pump diaphragms, aircraft hoses, seals and gaskets as well as
oil-lined tubing. Due to its versatility, nitrile is used in applications involving not only oil and fuel resistance, but
those applications requiring resistance to heat, abrasion, water, and gas permeability.
| Material | NBR(Nitrile Rubber/Buna-N) |
| Advantage | 1,Excellent Abrasion-Resistance,Good Rebound Resistance |
| 2,Good Tensile Strength and Elongation |
| 3,Excellent Animal and Vegetable Oil Resistance |
| 4,Good Oil and Fuel Resistance |
| 5,Good Water Resistance |
| Disadvantage | 1,Poor Oxygenated-Solvent Resistance |
| 2,Poor Ozone Resistance |
| Temperature | -40℃-120℃, -50℃-150℃(special formula) |
| Application | 1,Fuel tank, lubricating oil tank and oil in the hydraulic oil, gas, water, silicone grease, silicone oil and other fluid medium rubber parts, especially the sealing parts. |
| 2,It is currently the most widely used, the lowest cost of rubber seals. |
