Metallic Seals

Metallic seals are designed to make a seal by means of a ‘first line contact’ or ‘wedge action’ between the counter face (e.g. a flange) and the packing. The pressure on the sealing surface, exerted by the bolts, causes the ‘softer’ metal of the packing to flow into the microscopic structure of the harder flange material, thus creating an extremely strong and efficient seal.

Metallic seals are either made of one single metal or a combination of metals. In order to guarantee a proper, reliable seal, it is crucial to make the right choice of profiles and material.

One of our customers had a sealing issue with an existing product. Reason for failure were very small marks on the sealing surface.

2. O-Rings Class A+

Normally an O-Ring will create a block and seals. For this specific application a controlled leakage was mandatory and standard O-Rings failed due to the existing tolerances.

3. Oil Reduction Rod Seal Improvement

One of our customers had a sealing issue with an existing rod seal. Reason for failure was unknown but oil leakage was considered to be too high.

4. One piece Oil Seal Design

During this operation you need at least two people to install the seal. Also leakage can occur and parts can damage each other during installation. For these reasons our client requested us to find a solution.
