Oil seals are typically made of rubber or synthetic materials that are resistant to oil, heat, and pressure. They are designed to withstand the harsh conditions within an engine or machinery, such as high temperatures and varying levels of pressure. The seal is usually placed in a housing or a groove in order to effectively seal the gap between two moving parts.

3. Thermal Performance The spacing of wall ties can affect the thermal efficiency of the wall. Too many ties can reduce the insulation effectiveness by creating thermal bridges, which can lead to increased energy costs for heating and cooling the building. Optimizing tie spacing helps preserve the cavity's insulating properties.

One of the primary functions of masonry tie backs is to resist lateral forces
. Wind loads, for instance, can exert substantial pressure on a building’s facade. In the absence of adequate support, upper portions of the wall may lean or bulge, jeopardizing the entire structure. Tie backs are strategically placed to connect the wall to a substantial anchor in the ground or to other structural elements. This connection helps distribute the force over a larger area, significantly improving stability.
