Metal CS-Ring for Internal Pressure (CSI) and External Pressure (CSE) are designed for high pressure and excellent tightness performance (system pressure energised). They require high bolting load and have good spring back.

Non-vented rings (OI and OE) are intended for lower weight ranges. The flawlessly shut O Ring outline stays away from entrance of the media into the seal. Moderate burden, moderate weight ability. Inside (OVI) or remotely (OVE) vented O Rings are intended for higher weight. Other than the own seating stack the seal is additionally stimulated by the framework weight. Spring-empowered metal O Ring for Internal weight (OSI) and (OSE) for outer weight are intended for amazing low spillage at moderate weights. Gas filled metal O Ring for high temperature and moderate weight applications. OGI for interior weight and OGE for outer weight.
