| O' RINGS |
|
|
O'rings are torus or doughnut
shaped rings defined by their
Inner Diameter (I.D) & Cross Section (C.S).
ISG provides quality 'O' Rings from as
small as
0.74MM (I.D) to 1800MM (I.D) GIANT
size
without joints (Die Made) in all
Elastomers. |

| X' RINGS / FOUR LOBED RINGS |
|
 |
X RINGS also known as Four Lobed Rings are used in a variety of static & dynamic sealing applications.
The Four Lobed design provides twice the sealing surface in comparison to a standard Orings.
The double seal action requires less squeeze reducing friction & improving seal life.
X RINGS outperform standard Orings in rotary seal applications. The four lobed configuration avoids spiral twisting.
It allows the use of a more narrow groove width than a standard Oring groove but works fine even in a standard Oring groove. |

| BACKUP RINGS |
|
• FLAT BACK UP |
| • CONTOUR BACK UP |
| • NO BACK UP RING |
• ONE BACK UP RING |
• TWO BACK UP RINGS |
|
Backup rings prevent extrusion "O" Rings
In high pressures usually above 1500 PSI& Compensate for loose fitting components.
One backup ring should be used on each side of the oring in double acting assemblies if possible two backups should be used even in single acting assemblies.
If only one backup ring is used, the "O" RING should be placed between the pressure source & the backup ring.
