TECHNIC DATA |
| Properties |
Extremely high loads, good hardness, good heat conductivity, very high reliability against extrusion, high abrasive strength |
| Operating conditions |
For highest mechanical loads, high speeds and pressures medium frequencies, higher temperatures. |

SET UP
SPGO piston seals can be fitted on single-piece pistons. The O-ring is first inserted followed by the profile ring being pushed over. When fitting the seal, it is necessary to ensure the correct arrangement of the seal edge relative to the direction of the pressure. An assembly tool eases installation of small rings. |
