High Temperature Metal Bellow Seal, Packaging Type : Box

The MBG metal bellow seals are widely utilized in applications involving High temperature oils and hydrocarbons. These seals offer several advantages in such environments. One notable feature of the MBG seal is its high degree of axial flexibility, which allows it to compensate for shaft misalignment or lack of concentricity. This flexibility enables the seal to maintain effective sealing performance even in situations where the shaft undergoes thrust movement.  Additionally, the MBG seals are particularly well-suited for high-temperature applications commonly found in industries such as refineries, petrochemical plants, and the oil and gas sector. The seals are designed to withstand the extreme temperatures typically encountered in these environments. This makes them a reliable sealing solution for processes involving hot oils, hydrocarbons, and other high-temperature fluids.  An important advantage of the MBG seals is that it incorporates Flexible Graphite as a secondary Seal which can withstand high temperatures.
This makes MBG as an ideal solution for very high temperature thermic fluid sealing.
