Description
These Internal Pressure Face Spring Energized Seals are designed to prevent internal pressure or media exiting between two faces. This seal has low friction should there be movement between the surfaces. Conversely, when designing systems that seal equipment from external pressure, the groove's the inside diameter (ID) is primary. This design technique minimizes movement of the O-ring in the groove due to pressure, thereby virtually eliminating wear and pumping leakage. If this principle is used, groove diameters larger or smaller than indicated may be used.
Internal Pressure Face Spring Energized Seals are used for static, slow-rotating, or oscillating equipment such as low-temperature flange seals or cap applications. High seal loads and face seals are ideal for gas and vacuum applications. Depending on the application, there are a variety of sealed jack materials and power types.

Features
The features of this Internal Pressure Face Spring Energized Seal are as follows:
● Outstanding dry-running characteristics.
● Lower wear, low friction. The reinforced surface has a sturdy structure and a long service life.
● Variable friction conditions through the choice of spring characteristics. Precision-machined from high-quality spring steel. It has a tiny volume, good elasticity, high precision, and long-term durability.
● Extremely low breakaway forces even after prolonged downtimes.
● No stick-slip even with low sliding speed.
● The whole is exposed to a high-pressure treatment that makes it difficult to deform or break.
