The distance between the sealing surfaces of two flanges is larger than the initial state in operation. At this time, the tightness between gaskets and the sealing surfaces of flanges is guaranteed by the resilience of gaskets. It can be said that in the initial sealing stage, the plastic deformation of gasket surface plays a decisive role in ...

These microscopic features of any surface are particularly important to sealing performance. Surface finish is a complex and in-depth subject that has many facets of analysis to describe the texture or topography of a surface. In the world of seals, surface roughness is typically used to describe the finish condition of a sealing surface.

A rubber like material can easily conform to rough and uneven surfaces to provide effective sealing. While PTFE might be considered a relatively soft plastic, it's still many times harder than most O-Ring materials. Rather than "squishing" into a microscopic gap in the surface to seal it, a harder material will merely bridge the imparity ...

When designing a gland in which an O-ring or elastomeric seal is the desired sealing component, there are several aspects that need to be considered. A perfectly designed seal with the right material, ideal compression, gland fill and stretch can have inadequate sealing capability if the surface finish of the hardware is neglected.

Some surfaces may need to be sanded or ground until perfectly smooth for the sealant to bond appropriately. Penetrating sealers are more forgiving in this regard than acrylic, epoxy, or polyurethane sealants. If the concrete already has had sealant applied, we recommend stripping it from the surface before resealing.
